Client Spotlight: Lake Hopatcong Foundation

This month we are launching the first blog in our Client Spotlight Blog Series! Each spotlight will feature one of our important client relationships in order to give you an inside look at our collaboration. We pride ourselves on forming strong ties with organizations that share our values of creating a better future for people and our planet. So we are excited to be able to share snippets of the incredible teamwork we’ve been able to accomplish over the years!

At Princeton Hydro, we value our client relationships, as the collaborative work we are able to complete with organizations like the Lake Hopatcong Foundation (LHF) reaches exponentially further than anything we could complete alone. One of the reasons our organizations have such strong symmetry is that our values align and complement each other.

As their mission states,”Lake Hopatcong Foundation dedicates itself to protecting the lake environment and enhancing the lake experience, bringing together public and private resources to encourage a culture of sustainability and stewardship on and around New Jersey’s largest lake, for this and future generations.” We are so proud to help protect New Jersey’s largest lake with LHF.

We have been working with LHF since its inception in 2012, which is why we are excited to feature them in our first client spotlight blog. We spoke with Jessica Murphy, President/Executive Director of the Foundation, and Donna Macalle-Holly, Grants and Program Director, to give you an insider look at the organization:

Q: What makes the Lake Hopatcong Foundation unique?

A: The Lake Hopatcong Foundation is unique in that our mission spans a wide spectrum of activities. In addition to projects that focus on the lake environment, we also take on initiatives that support education, safety, community-building, recreation, and even arts and culture. The lake is split between two counties and four towns, so bringing the community together for all these things is very important to us, in addition to making sure the lake itself is healthy.

Q: What does the Lake Hopatcong Foundation value?

A: During our strategic planning process, the board and staff developed a list of values that we go back to when operating and making decisions. They are:

  • Collaboration – We operate in a way that brings people together throughout the community.
  • Action – We are committed to our mission, moving quickly to take on projects that have an impact on and around the lake.
  • Sustainability – We are forward-thinking when making decisions, taking future generations into account when considering projects and initiatives.
  • Warmth – We are a friendly face to the community, showing the best of ourselves and bringing out the best in the people of Lake Hopatcong.

Q: How long have you been working with Princeton Hydro?

The Lake Hopatcong Floating Classroom ready for take off!

When we first started the Lake Hopatcong Foundation in 2012, Dr. Fred Lubnow was kind enough to do a water quality presentation as one of our very first events as an organization! In the years since, we’ve worked closely with Princeton Hydro, particularly in a support role as they conduct business with the Lake Hopatcong Commission. The Lake Hopatcong Commission is a state entity created in 2001 through the Lake Hopatcong Protection Act dedicated to protecting the water quality of Lake Hopatcong and to preserve the natural, scenic, historical and recreational resources of the lake. LHF funded Princeton Hydro’s water quality monitoring during the years that the Commission ran out of money

Q: What types of services has Princeton Hydro provided to your organization?

A: In addition to water quality monitoring on the lake, Princeton Hydro has led volunteer training for us in our efforts to prevent the spread of invasive species and to teach local students in our spring field trip program. Dr. Lubnow has also worked alongside us in applying for grants and in providing insight and expertise for other environmental projects at the lake, including helping guide the installation of floating wetland islands, and helping our NJ Lakes Group to work with NJDEP on Harmful Algal Bloom (HAB) policies. He even did a quick fact check on our children’s book, Lake Hopatcong Speaks Out, before we published it!

Q: Do you have a favorite or most memorable project we’ve worked on together?

Princeton Hydro’s Senior Project Manager, Christopher Mikolajczyk, CLM, presenting during a Water Scout training held by the Lake Hopatcong Foundation.

A: The days that Chris Mikolajczyk spent teaching our volunteers about how to find and remove water chestnuts from the lake were a lot of fun, particularly because we were kayaking on the lake for it! And, also because the kayak we provided Chris was too small for him, and he had to scrunch in to fit, but he was a trouper and paddled on.

Q: What are some exciting things your organization is working on right now?

A: We are working closely with Princeton Hydro and LHC on a series of projects, funded through NJDEP grants, LHC, LHF, and local governments, that we hope will prevent and mitigate HABs on the lake. Those projects include aeration systems, phosphorus-locking technologies, and stormwater infrastructure upgrades. We’re excited to see how effective each can be. Also, on August 7 at 12:30, Dr. Lubnow will be presenting the Lake Hopatcong water quality monitoring project results at LHF’s “Thirst for Knowledge” lunch-and-learn webinar series, which was created to share information and discuss topics of interest to our lake community. To register for the free webinar, visit lakehopatcongfoundation.org.

Q: What drives you to want to go to work every day?

A: All of us at Lake Hopatcong Foundation have a passion for this lake and want to see it protected; we have a love for the community that surrounds it, too. Jessica Murphy grew up on the lake, met her husband here, and now is raising her four children to love the lake, too. Donna Macalle-Holly also met her husband on Lake Hopatcong, lives on the lake, and has worked professionally to take care of it for nearly two decades. Everyone in our office has made memories on Lake Hopatcong and developed friendships with those who live and work here. Those personal connections fuel our passion for what we do.

Q: How can Princeton Hydro support you/your organization in the future?

A: Continue to be the incredible resource you are! We are so fortunate to have the deep knowledge and expertise that Fred and your entire team provide, and we look forward to continuing to work together in the years ahead.

Some recent projects we are/have been working on with LHF include installing biochar bags to help control phosphorus levels and applying Phoslock to help mitigate harmful algal blooms! Because of our history working on Lake Hopatcong, we too have gained a passion for protecting and maintaining this lake. This incredibly important work could not be done without the genuine devotion and dedication from the Lake Hopatcong Foundation. We look forward to continuing great work with this incredible group!

Using an Ancient Technology in a New Way: Preventing Algal Growth with Biochar

The use of biochar, a pure carbon, charcoal-like substance made from organic material, to enhance soil fertility is thought to have originated over 2,000 years ago in the Brazilian Amazon. Archeological studies indicate populations of native Amazonians used biochar to amend nutrient-poor soils to increase agricultural productivity.

Biochar is generally produced through a process called pyrolysis. Pyrolysis is the decomposition of organic matter brought about by high temperatures (typically 800°F) in an environment with limited oxygen. The word pyrolysis is coined from the Greek-derived elements pyro “fire” and lysis “separating.”

Recently, biochar has received tremendous attention and its usage has moved beyond traditional agricultural and landscaping soil amendment applications. It is being championed as a useful technique for soil restoration, carbon sequestration, and – the one we’re most excited about – water quality management.

That’s right! Biochar has been shown to improve water quality by removing dissolved phosphorus from fresh waterbodies limiting algal growth and reducing the likelihood of harmful algae blooms (HABs).

Biochar can be placed in floatation balls, cages, or sacks, which are then tethered along the shoreline and in critical locations throughout the waterbody, like where an inlet enters a lake.

The benefits of biochar far outweigh the relatively low-cost investment. In addition to phosphorus removal and algal growth prevention, once the biochar’s capacity to absorb phosphorus has been exhausted, it can be re-purposed as compost for soil enrichment.

Princeton Hydro recently installed biochar flotation bags in various locations throughout Lake Hopatcong, including the Lake Winona outlet, the Lake Forest Yacht Club inlet, Lakeside Avenue and Holiday Avenue inlet in Hopatcong, and the Edith Decker School outlet in Mount Arlington.

The biochar bag installation, which was funded by the NJDEP Freshwater HABs Prevention & Management Grant provided to the Lake Hopatcong Commission (LHC) and its project partner the Lake Hopatcong Foundation (LHF), is one part of a multi-pronged lake management plan that aims to prevent the development of HABs and protect the overall water quality of Lake Hopatcong. Last summer, Lake Hopatcong – along with freshwater lakes throughout the country – was hit hard by a HAB outbreak that caused beach closures, health advisories, and water quality degradation.

Princeton Hyrdo has been working with the LHC, LHF, Morris & Sussex Countys, and local municipalities to implement a number of lake management strategies, including the recent dispersal of Phoslock, a different type of HAB-battling material, in Landing Cove, which was the largest application of Phoslock ever completed in the Northeast. Read more about it in our recent blog:

Mitigating Harmful Algal Blooms at Lake Hopatcong: Largest Application of Phoslock in Northeast

The team also installed Floating Wetland Islands, which use a mix of microbes and native plants to remove excess algae-causing nutrients from the water, in different areas of Lake Hopatcong.

Over the coming weeks, our team is installing more biochar bags in Roxbury, NJ at Duck Pond and in Mount Arlington, NJ at Memorial Pond. Stay tuned for more info! To learn more about our water quality management services, go here: bit.ly/pondlake.

6 Ways to Celebrate Lakes Appreciation Month

July is Lakes Appreciation Month – a great time of year to enjoy your community lakes and help protect them.

Lakes Appreciation Month was started by North American Lake Management Society (NALMS) to help bring attention to the countless benefits that lakes provide, to raise awareness of the many challenges facing our waterways, and to encourage people to get involved in protecting these precious resources.

“You work and play on them. You drink from them. But do you really appreciate them? Growing population, development, and invasive species stress your local lakes, ponds, and reservoirs. All life needs water; let’s not take it for granted!” – NALMS

Chemical pollutants, stormwater runoff, hydrocarbons, invasive aquatic species, and climate change are just a few of the the serious threats facing lakes and other freshwater habitats. So what can you do to to help?


We’ve put together six tips to help you celebrate Lakes Appreciation Month and get involved in protecting your favorite lakes:

1. Join the “Secchi Dip-In” contest

The “Secchi Dip-In” is an annual citizen science event where lake-goers and associations across North America use a simple Secchi disk to monitor the transparency or turbidity of their local waterway. Created and managed by NALMS, volunteers have been submitting information during the annual Dip-In since 1994. Get all the Dip-In details here.

2. Monitor and report algae blooms

With the BloomWatch App, you can help the U.S. Environmental Protection Agency understand where and when potential harmful algae blooms (HABs) occur. HABs have the potential to produce toxins that can have serious negative impacts on the health of humans, pets, and our ecosystems. Click here to learn more and download the app here. For more information on HABs, check out our recent blog.

3. Commit to keeping your lake clean

Commit to keeping your lake clean: Volunteers play a major role in maintaining the health and safety of community waterways. If you’re interested in helping to conserve and protect your water resources, you can start by cleaning up trash. Choose a waterbody in your community; determine a regular clean-up schedule; and stick to it! Cleaning your neighborhood storm drains really helps too; click here to find out how.

4. support your local lake

You can help support your favorite lake by joining or donating to a lake or watershed association. As an organized, collective group, lake associations work toward identifying and implementing strategies to protect water quality and ecological integrity. Lake associations monitor the condition of the lake, develop lake management plans, provide education about how to protect the lake, work with the government entities to improve fish habitat, and much more.

5. Get outside and enjoy (safely)

There are countless ways to enjoy and appreciate your community lakes. During Lakes Appreciation month, take photos that illustrate how you appreciate your community lakes, share them on social media using the hashtag: #LakesAppreciation, and hopefully you’ll inspire others to show their Lake Appreciation too.

6. ENTER the Lakes Appreciation Challenge

NALMS invites you to participate in its social media photo contest, titled “Show Your Lakes Appreciation Challenge.” To participate: Take a picture of yourself or someone you know enjoying or working on a lake or reservoir during July. And, upload the photo to Facebook, Instagram and/or Twitter using a descriptive caption and the #LakesAppreciation hashtag. Three winners will be determined via a raffle and announced via social media on Monday, August 3rd. Learn more.

Mitigating Harmful Algal Blooms at Lake Hopatcong: Largest Application of Phoslock in Northeast

To prevent harmful algal blooms (HABs) in New Jersey’s largest lake, a clay-based nutrient inactivating technology called Phoslock, is being applied in Lake Hopatcong this week. This is the largest Phoslock treatment to occur in the Northeastern U.S. The Phoslock treatment, which is happening in the southern end of the lake called Landing Channel, is expected to take approximately one week depending on the weather conditions.

Over the course of the 2019 summer season, Lake Hopatcong suffered from large-scale and persistent HABs causing local and county health agencies to close off all beaches and issue advisories over large sections of the lake. These unprecedented conditions had significant negative impacts on the ecological, recreational, and economic resources of the lake and region. In order to combat HABs in this upcoming 2020 summer season, the Lake Hopatcong Commission has partnered with the Lake Hopatcong Foundation, four municipalities (Jefferson, Hopatcong, Mt. Arlington, and Roxbury), two counties (Morris and Sussex), and their environmental consultant, Princeton Hydro, to develop both short- and long-term lake management strategies.

“The negative effects of HABs in our lake last year were numerous, widespread, and in some cases devastating,” recalled Donna Macalle-Holly of Lake Hopatcong Foundation. “It is imperative for every stakeholder to pool our resources to keep it from happening again. Collaboration is the only way to protect public health, as well as the health of New Jersey’s largest lake.”

In an effort to evaluate a variety of innovative in-lake and watershed-based measures to prevent, mitigate, and/or control harmful algal blooms in Lake Hopatcong, the Lake Hopatcong Commission was awarded a $500k grant as part of New Jersey Department of Environmental Protection’s (NJDEP) new $13.5M initiative to reduce and prevent future harmful algal blooms in New Jersey. In addition to the $500k grant, the aforementioned local government and nonprofit stakeholders provided $330k in matching funds to implement and evaluate a variety of ways to address HABs in Lake Hopatcong.

“Our lake community cannot sustain another year like 2019,” said Lake Hopatcong Commission Chairman Ron Smith. “Since the news of our grant award in early March, we have been working with our partners to make sure the projects are implemented in time for the 2020 season.”

This week, the water resource engineering and natural resource management firm, Princeton Hydro—a lake management consultant to Lake Hopatcong for over two decades—is implementing the first and largest innovative measure as part of the NJDEP HABs grant-funded project. This involves treating 50 acres of the southern end of the lake with Phoslock, a clay-based product that inactivates phosphorus in both the water column and the sediments, making this critical nutrient unavailable for algal growth. The Phoslock treatment, which requires proper permitting by NJDEP, is applied as a slurry and will be distributed from a boat. The slurry will temporarily make the water appear turbid, but should disperse approximately two to six hours after each treatment.

“We are expecting the Phoslock treatment to limit the growth of algae and therefore reduce the occurrence of harmful algal blooms in the lake this summer, keeping it open for recreation and business,” said Dr. Fred Lubnow, Director of Aquatic Resources at Princeton Hydro and leading HABs expert. “If this technology is deemed successful and cost-effective in Lake Hopatcong, we could set the precedent for large-scale HABs prevention in other lakes throughout New Jersey, and even across the nation.”

Developed by the Australian national science agency CSIRO, Phoslock is frequently used to strip the water column of dissolved phosphorus, as well as to inactivate phosphorus generated from deep, anoxic sediments. Recently, at a smaller scale, it has been shown to inactivate the mobilization of phosphorus from shallow sediments where there is a mobilization of phosphorus from both chemical and biological processes.

Algae uses phosphate, the biologically available form of phosphorus, as a food source to grow. When there is an excessive amount of phosphorus in a lake, algal growth can be dense and can negatively affect water quality. This excessive plant growth, caused by eutrophication, can both cause a lack of oxygen available, leading to fish kills, as well as produce harmful algal blooms with cyanotoxins, which are harmful to humans and pets.

After Phoslock is applied, it sinks through the water column, binding phosphate as it moves towards the sediment. Once settled at the bottom of the lake, it forms a very thin layer and continues to bind phosphate released from the sediment, thus controlling the release of phosphorus into the lake. One pound of phosphorus has the potential to generate up to 1,100 lbs of wet algae biomass. However, 1.1 tons of Phoslock is capable of removing 24 pounds of phosphorus — that’s over 26,000 lbs of wet algae biomass not growing in the lake for every 1.1 ton of Phoslock applied. In turn, Phoslock’s ability to suspend biologically available phosphorus is therefore a major step towards improving a lake’s water quality.

As part of the NJDEP HABs grant funding, the stakeholder group will be evaluating the relative effectiveness of this treatment strategy. Because of its shallow depth and separation from the main lake, the Landing Channel area was a good candidate for evaluation of this technology. Princeton Hydro will conduct pre- and post-treatment monitoring of the Phoslock treatment area in order to conduct an objective evaluation of the cost effectiveness of the treatment as a means of preventing the development and/or mitigation of HABs. If the study indicates that Phoslock is a cost-effective treatment, the Lake Hopatcong Commission may consider additional trials in other sections of the lake, if funding is available.

Identifying, Understanding and Addressing Harmful Algae Blooms

NJDEP Releases Updated Guidance for Harmful Algal Blooms

Last summer, 39 of New Jersey’s lakes were plagued with toxic algae outbreaks, also known as harmful algae blooms or HABs, causing major water quality degradation, beach closures and health advisories. In response, the NJDEP implemented a unified statewide approach to addressing HABs in freshwater recreational waters and sources of drinking water, and protecting the public from risks associated with exposure to cyanobacteria.

Last week, NJDEP announced a new component to its statewide Cyanobacterial HAB Response Strategy: a color-coded health alert index that provides precise recreational use recommendations for impacted waterbodies based on levels of cyanobacteria and/or cyanotoxins present. The index has six tiers – NONE, WATCH, ALERT, ADVISORY, WARNING, and DANGER – each providing recommendations on the specific activities that should or should not be pursued based on water monitoring results.

“Princeton Hydro is proud to be one of the contributing factors in the development of the Updated Guidance for HABs,” said said Dr. Fred Lubnow, Director of Aquatic Resources for Princeton Hydro. “We feel this updated protocol will provide the necessary and objective information for State and local organizations to make informed and rational decisions, based on sound and scientifically-based data, on how to deal with HABs in a recreational setting.

Princeton Hydro and Clean Water Consulting are the technical advisers for the New Jersey Lake Group, who have met a number of times over the last 8 to 9 months to discuss the State’s guidance on dealing with HABs.  In late 2019, on behalf of the New Jersey Lake Group, Princeton Hydro and Clean Water Consulting developed a White Paper providing recommended changes for consideration to NJDEP’s Recreational Response Strategy to HABs.

“I’m proud to say that many of the provided recommendations were integrated into NJDEP’s Updated Guidance for HABs,” explained Dr. Lubnow.

WATCH
(Suspected or confirmed HAB with potential for allergenic and irritative health effects)
This warning will be posted when HAB cell counts exceed 20,000. In this scenario, public beaches remain open, but the index instructs the public to use caution, provides information on the potential less serious health effects, and allows for more informed decision-making.

ALERT
(Confirmed HAB that requires greater observation due to increasing potential for toxin production)
This warning indicates a public bathing beach closure only and is posted when a HAB has been confirmed with cell counts between 40,000 and 80,000 and no known toxins above the public threshold. Beaches remain open (dependent upon local health authority) and monitoring for future toxin production should be increased.

ADVISORY
(Confirmed HAB with moderate risk of adverse health effects and increased potential for toxins above public health thresholds)
Signs will be posted for this warning level when cell counts exceed 80,000 or when toxin levels exceed 3 micrograms per milliliter of microcystins. Public bathing beaches will be closed, but the waterbody will remain accessible to some “secondary contact” activities, like boating.

WARNING and DANGER
(Confirmed HAB with high risk of adverse health effects due to high toxin levels)
and (Confirmed HAB with very high risk of adverse health effects due to high toxin levels)
These tiers are designed to alert the public to the presence of HABs that are producing very high levels of toxins which justify additional caution. In some instances, the entire waterbody may be closed for all public use. New Jersey has experienced approximately 12 “warning level” HAB events over the last 3 years; monitoring has never indicated a “danger level” HAB event.

According to their press release, NJDEP is committed to working with local officials to implement the index and get signage posted at lakes throughout the state as soon as possible.

In order to create the health index, NJDEP scientists carefully reviewed HABs data collected over the last three years by Lake Hopatcong Commission, Lake Hopatcong Foundation, Princeton Hydro, and other sources. The tiered warning system will enable lake communities, residents and visitors to make more individualized decisions about what risks they are willing to take and what activities they feel comfortable engaging in at the various levels of HABs.

In the coming days, the NJDEP’s Harmful Algal Bloom website will be updated to include the new health index and accompanying signage, relevant monitoring data, and other information for each of the impacted bodies of water, as well as an updated HAB Monitoring and Response Strategy. For now, you can read the full press release and additional information here: https://www.nj.gov/dep/newsrel/2020/20_0023.htm.

NJ Takes Serious Steps to Prevent Harmful Algal Blooms

Photo by: Lake Hopatcong Commission

Last year, there were more than 70 suspected and 39 confirmed Harmful Algal Blooms (HABs) in New Jersey, which is significantly higher than the previous two years. New Jersey wasn’t the only state impacted by HABs. The increase caused severe impacts on lakes throughout the country, resulting in beach closures, restricting access to lake usage, and prompting wide-ranging health advisories.

In November, New Jersey Governor Phil Murphy and officials from the New Jersey Department of Environmental Protection (NJDEP) announced a three-pronged, $13 million initiative to reduce and prevent future HABs in the state. As part of the initiative, NJDEP hosted its first regional HABs Summit with the goal of prevention by improving communication throughout lake communities and sharing information ahead of the warmer months when HABs begin to appear.

The summit, which was held on January 28, 2020 at NJDEP’s Pequest Trout Hatchery and Natural Resource Education Center in Warren County included a Q&A panel discussion, information resource tables for one-on-one discussions, and presentations from a variety of NJDEP representatives and environmental experts. Princeton Hydro’s  Director of Aquatics and regional HABs expert Dr. Fred Lubnow’s presentation focused on how to properly and effectively manage HABs.

According to Dr. Lubnow, “Managing loads of phosphorous in watersheds is even more important as the East Coast becomes increasingly warmer and wetter thanks to climate change. Climate change will likely need to be dealt with on a national and international scale. But local communities, groups, and individuals can have a real impact in reducing phosphorous levels in local waters.”

In a recent press release from Governor Murphy’s office, the NJDEP Chief of Staff Shawn LaTourette said, “We will reduce HABs by working closely with our local partners on prevention and treatment techniques, while relying on the best available science to clearly communicate risk to the public. Our new HABs initiative will enhance the Department’s ability to evaluate statewide strategies and increase the capacity of lake communities to reduce future blooms.”

New Jersey’s new HABs initiative is comprised of three main components:

Providing Funding:

More than $13 million in funding will be available to local communities to assist in preventing HABs, including:

  • $2.5 million will be available as matching funds for lakes and HABs management grants, including treatment and prevention demonstration projects.

  • Up to $1 million in Watershed Grant funding will be made available for planning and projects that reduce the nonpoint source pollution, including nutrients, that contribute to HABs in surface waters of the State.

  • $10 million in principal forgiveness grants will be offered through the Clean Water State Revolving Fund for half of the cost, capped at $2 million, of sewer and stormwater upgrades to reduce the flow of nutrients to affected waterbodies.

Increasing Expertise & Implementing Prevention Tactics:

Per the Governor’s press release, “the second element of the initiative is to build upon the state’s scientific expertise and enhance its capacity to respond to HAB events. This includes establishing a team of experts from across various sectors to evaluate the state’s strategies to prevent HABs and pursuing additional monitoring, testing and data management capacity.”

Connecting with Communities:

The third component is focused on increasing NJDEP’s ability to communicate with affected communities. The regional HABs Summit held on January 28 was one of two Summits that will occur in early 2020 (the date of the next Summit has not yet been announced). NJDEP has also developed new web tools to provide HABs education, offer a forum to discuss and report potential HAB sightings, and better communicate HAB incidents.

Identifying, Understanding and Addressing Harmful Algae Blooms

Regional Watershed Planning: A Critical Strategy to Prevent HABs

Photo by @likethedeaadsea, submitted during our 2019 #LAKESAPPRECIATION Instagram Photo Contest.

Harmful Algae Blooms (HABs) were in the spotlight last summer due to the severe impacts they had on lakes throughout the country. Nation-wide, HABs caused beach closures, restricted lake usage, and led to wide-ranging health advisories. There were 39 confirmed harmful algal bloom (HAB) outbreaks in New Jersey alone.

As a reminder, HABs are rapid, large overgrowths of cyanobacteria. These microorganisms are a natural part of aquatic ecosystems, but, under the right conditions (primarily heavy rains, followed by hot, sunny days), these organisms can rapidly increase to form cyanobacteria blooms, also known as HABs. HABs can cause significant water quality issues; produce toxins that are incredibly harmful (even deadly) to humans, animals, and aquatic organisms; and negatively impact economic health, especially for communities dependent on the income of jobs and tourism generated through their local lakes.

“A property’s value near an infested lake can drop by up to $85,000, and waterside communities can lose millions of dollars in revenue from tourism, boating, fishing and other sectors,” reports Princeton Hydro President Geoff Goll, P.E.

Generally, the health of a private lake is funded and managed in isolation by the governing private lake association group. But, in order to mitigate HABs and protect the overall health of our local waterbodies, it’s important that we look beyond just the lake itself. Implementing regional/watershed-based planning is a critical step in preventing the spread of HABs and maintaining the overall health of our natural resources.

At the end of 2019, the Borough of Ringwood became the first municipality in New Jersey to take a regional approach to private lake management through a public-private partnership with four lake associations.

The Borough of Ringwood is situated in the heart of the New Jersey Highlands, is home to several public and private lakes, and provides drinking water to millions of New Jersey residents. In order to take an active role in the management of these natural resources, Ringwood hired Princeton Hydro, a leader in ecological and engineering consulting, to design a municipal-wide holistic watershed management plan that identifies and prioritizes watershed management techniques and measures that are best suited for immediate and long-term implementation.

Map showing the four private lakes involved in the Borough of Ringwood's regional holistic watershed management plan.

Funding for Ringwood’s Watershed-based Assessment is being provided by the New Jersey Highlands Council through a grant reimbursement to the Borough of Ringwood. The Highlands Council offers grant funding and assistance to support the development and implementation of a wide range of planning initiatives. Examples of the types of efforts that can be funded for municipalities and counties include:

  • Land Use and Development projects like sustainable economic development planning and green building and environmental sustainability planning;
  • Infrastructure projects like stormwater management and water use/conservation management;
  • Resource Management projects like habitat conservation, lake management and water quality monitoring; and
  • Recreation and Preservation projects like land preservation and stewardship, farmland preservation and agriculture retention, and historic preservation.

Chris Mikolajczyk, CLM, Princeton Hydro’s Aquatics Senior Project Manager and the Ringwood project’s lead designer, presented with Keri Green of the NJ Highlands Council, at a recent New Jersey Coalition of Lake Associations meeting. The duo showcased Ringwood’s unique approach, spread the word about available funding through the NJ Highlands Council, and encourage other municipalities to follow Ringwood’s lead in taking a regional approach to lake and watershed management.

Mikolajczyk said, “This regional approach to lake and watershed management is a no-brainer from a scientific, technical, and community point of view. Historically, however, municipal governments and private lake associations have rarely partnered to take such an approach. The hope is that the Borough of Ringwood efforts, funded by the New Jersey Highlands Council, will set a precedent for this logical watershed management strategy and open the door for future public-private partnerships.”

This integrated approach to watershed and lake management is an important preventative measure to improve water quality for millions of people and reduce potential future incidents of aquatic invasive species and harmful algal blooms throughout the region.

Identifying, Understanding and Addressing Harmful Algae Blooms

Harmful Algae Blooms (HABs) were in the spotlight this summer due to the severe impacts they had on lakes throughout the country. The nation-wide HABs outbreak caused beach closures, restricted access to lake usage, and wide-ranging health advisories.

What exactly are HABs? Why were they so severe this summer? Will this trend continue? Can anything be done to prevent the occurrence or mitigate the impacts?

In this blog, we provide answers to all of those questions, exploring what HABs are, why they occur, why they were particularly prevalent this summer, and what we can do to combat them.

What are HABs?

Simply put, HABs are rapid, large overgrowths of cyanobacteria. Cyanobacteria, also known as blue-green algae, aren’t actually algae, they are prokaryotes, single-celled aquatic organisms that are closely related to bacteria and can photosynthesize like algae. These microorganisms are a natural part of aquatic ecosystems, but, under the right conditions (primarily heavy rains, followed by hot, sunny days), these organisms can rapidly increase to form cyanobacteria blooms, also known as HABs.

HABs can cause significant water quality issues in lakes and ponds, often forming a visible and sometimes odorous scum on the surface of the water. They can produce toxins that are incredibly harmful (even deadly) to humans, animals, and aquatic organisms. HABs also negatively impact economic health, especially for communities dependent on the income of jobs and tourism generated through their local lakes and waterways.

What causes HABs?

HABs are caused by a complex set of conditions, and many questions remain about exactly why they occur and how to predict their timing, duration, and toxicity. Primarily, HABs are caused by warmer temperatures and stormwater run-off pollutants, including fertilizers with phosphates.

NY Times article, featuring Princeton Hydro, looks at how climate change affects lakes nationwide, using NJ as an example. Photo by: Rick Loomis, NY Times.HABs are induced by an overabundance of nutrients in the water. The two most common nutrients are fixed nitrogen (nitrates and ammonia) and phosphorus. Discharges from wastewater treatment plants, runoff from agricultural operations, excessive fertilizer use in urban/suburban areas, and stormwater runoff can carry nitrogen and phosphorus into waterways and promote the growth of cyanobacteria.

Climate change is also a factor in HAB outbreaks, which typically occur when there are heavy rains followed by high temperatures and sunshine. Climate change is leading to more frequent, more intense rainstorms that drive run-off pollutants into waterways, coupled with more hot days to warm the water. These are the ideal conditions for HABs, which in recent years have appeared in more places, earlier in the summer.

With climate change and increasing nutrient pollution causing HABs to occur more often and in locations not previously affected, it’s important for us to learn as much as we can about HABs so that we can reduce their harmful effects.

What Can I Do to Prevent HABs?

Signs on the closed beach at Hopatcong State Park warn residents of the Harmful Algae Bloom at Lake Hopatcong on July 2019, in Landing, NJ. (Photo by: Danielle Parhizkaran of NorthJersey.comThe number one thing individuals can do to protect their waterbodies and prevent HABs is to reduce phosphorous use and reduce nutrient loads to waters.

According to Dr. Fred Lubnow, Director of Aquatic Programs for Princeton Hydro, “Managing loads of phosphorous in watersheds is even more important as the East Coast becomes increasingly warmer and wetter thanks to climate change. Climate change will likely need to be dealt with on a national and international scale. But local communities, groups, and individuals can have a real impact in reducing phosphorous levels in local waters.”

Here are a few steps you can take to improve water quality in your community lakes:

Controlling stormwater runoff is another critical factor in improving water quality and reducing HABs. There are a number of low-cost green infrastructure techniques that can be implemented on an individual and community-wide scale. You can read more about green infrastructure stormwater management techniques in our recent blog.

In a recent Op/Ed published on NJ.com, Princeton Hydro President Geoff Goll lists four things that residents, businesses, and local governments should do to prevent another HABs outbreak next summer:

  1. Improve aging “gray” infrastructure
  2. Invest in “green” stormwater infrastructure
  3. Implement regional/watershed-based planning
  4. Pass the Water Quality Protection and Jobs Creation Act

“By making the necessary investments, we can simultaneously create jobs, reduce flood impacts, improve fisheries, maintain or increase lakefront property values, improve water quality and preserve our water-based tourism. The time to act is literally now,” said Geoff. Go here, to read the full article.

HABs Management in Action through Floating Wetland Islands:

Nitrogen and phosphorus are utilized by plants, which means they uptake these nutrients to sustain growth. We see this naturally occurring in wetland ecosystems where wetlands act as a natural water filtration system and can actually thrive from nutrients flowing in from external sources.

This process is replicated in floating wetland islands (FWIs), where you typically have a constructed floating mat with vegetation planted directly into the material. The plants then grow on the island, rooting through the floating mat.

Not only do FWIs assimilate and remove excess nitrogen and phosphorus out of the water, they also provide habitat for fish and other aquatic organisms; help mitigate wave and wind erosion impacts; provide an aesthetic element; and can be part of a holistic lake/pond management strategy. Because of this, FWIs are being utilized to improve water quality and control HABs in lakes and ponds throughout the country. Princeton Hydro has designed and implemented numerous FWIs in waterbodies large and small. Go here to learn how they’re being used in Harveys Lake.

 

Recognizing and monitoring the changes that are taking place in our local waterways brings the problems of climate change, stormwater pollution and the resulting water quality issues closer to home, which can help raise awareness, inspire environmentally-minded action and promote positive, noticeable change.

If you spot what you believe to be a harmful algae bloom in your community lake, contact your local lake association right away. They, along with their lake management team, can assess the situation and determine what further actions need to be taken.

BOROUGH OF RINGWOOD INITIATES FIRST-IN-STATE REGIONAL APPROACH TO LAKE MANAGEMENT THROUGH PUBLIC-PRIVATE PARTNERSHIP

NorthJersey.com File Photo
The Borough of Ringwood initiates a unique public-private partnership
with four community lake associations to
holistically manage watershed health related to private lakes

Providing drinking water to millions of New Jersey residents, the Borough of Ringwood is situated in the heart of the New Jersey Highlands and is home to several public and private lakes that sit within the Ramapo Mountains. In order to take an active role in the management of these natural resources within multiple watersheds, the Borough of Ringwood will be the first municipality in the state of New Jersey to take a regional approach to private lake management through a public-private partnership (PPP) with four lake associations.

The four private sets of lakes targeted in the plan— Cupsaw, Erskine, Skyline, and Riconda —were created by the Ringwood Company in the 1920s and 30s to promote the municipality as a hunting and fishing retreat and a summer resort. They currently provide private beach clubs and recreational opportunities for surrounding homeowners who can opt to join as members.

Map Showing the Four Private Lakes in the PPP holistic watershed management plan

Generally, the health of a private lake is funded and managed in isolation by the governing private lake association group. Ringwood Borough Manager Scott Heck’s concept was to design and implement a municipal-wide holistic watershed management plan to use as a tool to identify capital priorities to enhance water quality throughout the community. Mr. Heck hired Princeton Hydro, a leader in ecological and engineering consulting to design this innovative project.

Cupsaw Lake “This regional approach to lake and watershed management is a no-brainer from a scientific, technical, and community point of view. Historically, however, municipal governments and private lake associations have rarely partnered to take such an approach,” said Princeton Hydro’s Senior Project Manager, Christopher Mikolajczyk, who is a Certified Lake Manager and lead designer for this initiative. “We’re thrilled to work with the Borough of Ringwood and the New Jersey Highlands Council to set a precedent for this logical watershed management strategy, which opens the door for future public-private partnerships.”

As part of this project, a Watershed-based Assessment will be completed. The following objectives will be met:

  1. Identification, quantification, and prioritization of watershed-based factors which may cause eutrophication;
  2. Identification of watershed management measures needed to address general causes of water quality impairments;
  3. Identification of the relative cost of the recommended general watershed management measures;
  4. The generation of a schedule, based on priority, for the implementation of the recommended watershed management measures; and
  5. A general assessment report will be authored at the conclusion of the study.

Skyline Lake in the FallFunding for the Watershed-based Assessment for the Lakes of the Borough of Ringwood is being provided by the New Jersey Highlands Council through a grant reimbursement to the Borough of Ringwood. As part of the PPP , the Borough of Ringwood will review and where feasible implement any suggested actions surrounding the lakes. The final report, provided to the Borough by Princeton Hydro, will identify and prioritize watershed management techniques and measures that are best suited for immediate and long-term implementation, as well as provide cost projections for implementation in both the short-term and long-term.

This integrated approach to watershed and lake management is an important preventative measure to improve water quality for millions of people and reduce potential future incidents of aquatic invasive species and harmful algal blooms throughout the region.
