NJ Takes Serious Steps to Prevent Harmful Algal Blooms

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

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.

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 Bloom Visible in Owasco Lake. Photo by: Tim Schneider

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.

This illustration, created by Staff Scientist Ivy Babson, conveys the functionality of a Floating Wetland Island

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.

Washington Post’s Climate Story Features Princeton Hydro

Photo credit: The Washington Post

Did you know that New Jersey is one of the fastest-warming states in the nation? Not only that, did you know the average temperature increase in the state is double the average of the rest of the Lower 48 states?

In a recent article, the Washington Post uncovers quite startling findings from analysis of more than a century of National Oceanic and Atmospheric Administration temperature data across the Lower 48 states and 3,107 counties. The article takes a specific look at the impacts climate change has had on Lake Hopatcong.

Princeton Hydro has been working with Lake Hopatcong for 30+ years, restoring the lake, managing the watershed, reducing pollutant loading, and addressing invasive aquatic plants and nuisance algae bloomsLake Hopatcong has one of the longest, continuous, long-term ecological databases in New Jersey; 30+ years of consistently collected water quality data.

Dr. Fred Lubnow, Director of Aquatic Programs, and Katie Walston, Senior Scientist, are featured in the Washington Post article. Here’s an excerpt:

On a cool but sunny day in May, Fred Lubnow, director of aquatic programs at Princeton Hydro, and Katie Walston, a senior scientist there, pulled up their anchor in Lake Hopatcong to find it covered with aquatic weeds. The culprit? Fertilizer runoff combined with winters too warm to kill them off.

“The plants start growing earlier and linger around longer, as well,” Lubnow said. The thick ice blocked sunlight from nurturing the weeds. But “in some of these shallow areas, as early as February, we’re looking through the ice seeing the plants growing.”

By summer, the weeds become a nuisance, forcing the state government to “harvest” them with large paddles and toss them onto a conveyor belt, then onto barges. Some years, funding has been hard to get, delaying harvesting and angering homeowners.

“If this area is not harvested, you can’t get a boat through it,” Lubnow says. Swimming isn’t possible, either. Fishing becomes difficult.

Four Ways Climate Change Can Affect Your Lake

 

 

 

Managing Urban Stormwater Runoff and Revitalizing Natural Habitat at Harveys Lake

Measuring 630+ acres, Harveys Lake, located in Luzerne County, Pennsylvania, just northeast of Wilkes-Barre, is the largest natural lake (by volume) within the Commonwealth of Pennsylvania, and is one of the most heavily used lakes in the area. It is classified as a high quality – cold water fishery habitat (HQ-CWF) and is designated for protection under the classification.

Since 2002, The Borough of Harveys Lake and the Harveys Lake Environmental Advisory Council  has worked with Princeton Hydro on a variety of lake management efforts focused around maintaining high water quality conditions, strengthening stream banks and shorelines, and managing stormwater runoff.

Successful, sustainable lake management requires identifying and correcting the cause of eutrophication as opposed to simply reacting to the symptoms of eutrophication (algae and weed growth). As such, we collect and analyze data to identify the problem sources and use these scientific findings to develop a customized management plan that includes a combination of biological, mechanical, and source control solutions. Here are some examples of the lake management strategies we’ve utilized for Harveys Lake:

 

Floating Wetland Islands

Floating Wetland Islands (FWIs) are an effective alternative to large, watershed-based natural wetlands. Often described as self-sustaining, FWIs provide numerous ecological benefits. They assimilate and remove excess nutrients, like nitrate and phosphorous, that could fuel algae growth; provide habitat for fish and other aquatic organisms; help mitigate wave and wind erosion impacts; and provide an aesthetic element. FWIs are also highly adaptable and can be sized, configured, and planted to fit the needs of nearly any lake, pond, or reservoir.

Five floating wetland islands were installed in Harveys Lake to assimilate and reduce nutrients already in the lake. The islands were placed in areas with high concentrations of nutrients, placed 50 feet from the shoreline and tethered in place with steel cables and anchored. A 250-square-foot FWI is estimated to remove up to 10 pounds of nutrients per year, which is significant when it comes to algae.

Princeton Hydro worked with the Harveys Lake Environmental Advisory Council and the Borough of Harveys Lake to obtain funding for the FWIs through the Pennsylvania Department of Environmental Protection (PADEP).

 

Streambank & Shoreline Stabilization

Harveys Creek

The shoreline habitat of Harveys Lake is minimal and unusual in that a paved road encompasses the lake along the shore with most of the homes and cottages located across the roadway, opposite the lake. In addition to the lake being located in a highly populated area, the limited shoreline area adds to the challenges created by urban stormwater runoff.

Runoff from urban lands and erosion of streambanks and shorelines delivers nutrients and sediment to Harveys Lake. High nutrient levels in the lake contribute to algal blooms and other water quality issues. In order to address these challenges, the project team implemented a number of small-scale streambank and inlet stabilization projects with big impacts.

The work included the stabilization of the streambank downstream for Harveys Lake dam and along Harveys Creek, the design and installation of a riparian buffer immediately along the lake’s shoreline, and selective dredging to remove sediment build up in critical areas throughout the watershed.

 

Invasive Species Management

Hydrilla (Hydrilla verticillata), an aggressively growing aquatic plant, took root in the lake in 2014 and quickly infected 250 acres of the lake in a matter of three years. If left untreated, hydrilla will grow to the water’s surface and create a thick green mat, which prevents sunlight from reaching native plants, fish and other organisms below. The lack of sunlight chokes out all aquatic life.

In order to prevent hydrilla from spreading any further, Princeton Hydro and SePRO conducted an emergency treatment of the impacted area utilizing the systemic herbicide Sonar® (Fluridone), a clay-based herbicide. SonarOne, manufactured by SePRO, blocks hydrilla’s ability to produce chloroplasts, which in turn halts the photosynthetic process. The low-concentration herbicide does not harm fish, wildlife or people using the lake. Surveys conducted after the treatment showed it was working – the hydrilla had turned white and was dying off. Additional Sonar treatments followed and efforts to eradicate hydrilla in the lake continue.

Dr. Fred Lubnow, our Director of Aquatic Programs, estimates complete eradication of the aquatic plant could take around five years. Everyone can do their part in preventing the spread of this and other invasive species. Boaters and lake users must be vigilant and remove all vegetation from the bottom of watercrafts and trailers.

 

Stormwater Best Management Practices (BMPs)

In 2009, Princeton Hydro developed a stormwater implementation plan (SIP) for Harveys Lake. The goal of the stormwater/watershed-based efforts was to reduce the lake’s existing annual total phosphorus load to be in full compliance with the established Total Maximum Daily Load (TMDL). This TMDL is related to watershed-based pollutant loads from total phosphorus (TP) and total suspended solids (TSS), which can contribute to algal blooms.

A number of structural urban runoff projects were implemented throughout the watershed. This includes the design and construction of two natural stream channel projects restoring 500 linear feet of tributaries and reducing the sediment and nutrient loads entering the lake. A series of 38 urban runoff BMPs, including nutrient separating devices and roadside infiltration, were installed in areas immediately adjacent to the lake to further reduce the loads of nutrients and other pollutants reaching the lake.

The photos below show a stormwater project that was completed in the Hemlock Gardens Section of the Watershed. Hemlock Gardens is a 28-acre section of land located in the southeastern portion of the watershed. It contains approximately 26 homes, has very steep slopes, unpaved dirt roads, and previously had no stormwater infrastructure in place.

Two structural stormwater BMPs were installed:

  • A nutrient separating baffle box, which utilizes a three-chamber basin with screens to collect leaf litter, grass clippings and trash
  • A water polishing unit that provides a platform for secondary runoff treatment

In 1994, Harveys Lake was identified as “impaired” by PADEP due to large algal blooms. In 2014, Harveys Lake was removed from the list of impaired waters. Project partners attribute the recovery of this lake to the stream restoration, urban runoff BMP implementation, and the use of in-lake nutrient reduction strategies.

The Harveys Lake Watershed Protection Plan Implementation Project proved that despite the lake being located in an urbanized watershed, it is possible to implement cost-effective green infrastructure and stormwater retrofit solutions capable of significantly decreasing pollutant loading to the lake.

GETTING STARTED:

Not sure how to get started? We’ve got you covered with a few ideas! Here are 10 ways you can show your lake appreciation:

  1. Relax on the lake: Whether you enjoy swimming, relaxing on the shoreline, sailing, canoeing, or kayaking, there are countless ways you can get outside and enjoy your community lakes.
  2. Go fishing: There’s nothing quite like relaxing on the shoreline with a fishing pole in your hand. Whether you’re there to catch and release or want to take your catches home, fishing is a great way to unwind. Go get your license (if you’re above the age of 16), check your local fishing rules and regulations, and cast a line in your local lake!
  3. new jersey ospreyBreak out the binoculars:  Lakes are great spots to go birding! Download the eBird app to track your bird sightings and see what fellow birders have reported in the area. Also, keep your eyes peeled for ospreys; New Jersey has an osprey conservation project with a map to track all the recent sighting reports.
  4. #TrashTag – Clean it up: One super quick and easy thing to do is clean up your local lake. You can get a small group of friends together or just go out on your own – no effort is too small! You’ll be able to immediately see the benefits of your actions when the trash-lined shore is clear. In addition to the Lakes Appreciation Photo contest tags, make sure you use #trashtag, a global viral cleanup challenge that shows people’s before and after pictures of their cleaning efforts so that you can be a part of that growing trend!
  5. Get involved with your local lake: You can help support your favorite lake by joining 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.
  6. Remove invasive species: One of the most harmful elements of lake ecosystems are invasive species. So, by properly removing and discarding them, you can really help a lake to achieve its most desired state. A list of possible invasive species can be found here. For inspiration, check out this blog, written by our Senior Limnologist, Mike Hartshorne.
  7. Call on your inner-artist and draw a lake scene: All you need is a notepad, a pencil, and some spare time to let your imagination and creative skills take over. Does your lake have ducks? Are there people swimming? Is the sun rising or setting? Snap a picture of you with your art!
  8. 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. Learn more and download the app.
  9. Join the “Secchi Dip-In” contest: The “Secchi Dip-In” is an annual citizen science  event created by NALMS during which lake-goers and associations across North America use a simple Secchi disk to monitor the transparency or turbidity of their local waterway. Visit their website to find out how to join their contest!
  10. Create your own experience: Write a sonnet about one of your lake experiences. Snap a picture of you sitting out by the water’s edge. Share your favorite lake memory on social media. Collect shells. Play a round of SpikeBall or CanJam in the surrounding area. With permission from the lake owner, plant some native species around the water. The possibilities are endless for lake appreciation!

Still having trouble thinking of an activity to do? Visit the NALMS’s website!

Protecting Greenwood Lake’s Water Quality Through Stormwater Management

The summer is upon us and Lakes Appreciation Month is right around the corner, what better time to pay a visit to and learn more about the lakes in your area.

Princeton Hydro conducts work on lakes throughout the Northeast to preserve, protect and improve water quality and ecological health, ensuring that your community lakes can be enjoyed now and into the future. Today, we’re putting the spotlight on Greenwood Lake:

Greenwood Lake, a 7-mile-long interstate lake that straddles the border of New York and New Jersey, is a popular recreation spot for residents and tourists of both states. Considered to be one of the top bass fishing lakes in New Jersey, Greenwood Lake is abundant with largemouth and smallmouth bass, yellow perch, chain pickerel and catfish. The lake is also extensively used by residents for swimming and boating.

For over 35 years, Princeton Hydro’s scientists have worked with New Jersey, local governing municipalities, and the various environmental organizations involved with the protection of Greenwood Lake and its watershed. In the early 2000s, we developed a comprehensive Restoration Plan and a proactive monitoring program that we have used over the years to properly manage the lake and its watershed. The plan was developed for the Greenwood Lake Commission and the Township of West Milford with funding provided through the New Jersey Department of Environmental Protection’s Nonpoint Source 319(h) Program. The Restoration Plan focuses heavily on the implementation of various types of stormwater best management practices (BMPs) to help reduce the influx of sediment and nutrients into the lake. We track the positive effects and benefits achieved through these stormwater projects by conducting both storm-event based and in-lake water quality monitoring.

The goal of the stormwater-based efforts is to ensure the lake’s total phosphorus (TP) load is systematically reduced in accordance with the lake’s established Total Maximum Daily Load (TMDL). The TMDL is a regulatory term in the U.S. Clean Water Act, that identifies the maximum amount of a pollutant (in this case phosphorus) that a waterbody can receive while still meeting water quality standards. Princeton Hydro was instrumental in developing the TMDL for Greenwood Lake. Phosphorus entering the lake from runoff is the primary driver of the lake’s eutrophication. The direct results of eutrophication are increases in the density of aquatic plants and nuisance algae. All this added productivity leads to reduced clarity, reductions in dissolved oxygen concentrations, and a number of other ecological impacts that compromise the quality, aesthetics, and use of the lake.

Last year, Princeton Hydro and the Greenwood Lake Commission, with input from the West Milford Environmental Commission, proposed an updated Watershed Implementation Plan (WIP) for the lake. Approved and funded by the NJ Highlands Council, the updated WIP includes a variety of components that build upon the original Restoration Plan and incorporate newly advanced stormwater management and Nonpoint Source Pollution (NPS) reduction technologies.

The WIP includes in‐lake and stream monitoring; the assessment of the existing stormwater structures installed through grant‐based, watershed activities; and the identification of watershed-based projects that can be completed to support the Lake’s compliance with TMDL TP levels with a specific focus on the stormwater runoff produced by Belcher’s Creek, a major tributary to Greenwood Lake.

The WIP also includes the following nine minimum elements considered necessary by both NJDEP and USEPA for funding eligibility:

  1. Identify causes and sources of pollution
  2. Estimate pollutant loading into the watershed and the expected load reductions
  3. Describe management measures that will achieve load reductions and targeted critical areas
  4. Estimate amounts of technical and financial assistance and the relevant authorities needed to implement the plan
  5. Develop an information/education component
  6. Develop a project schedule
  7. Describe the interim, measurable milestones
  8. Identify indicators to measure progress
  9. Develop a monitoring component

While many of these elements have been indirectly addressed to varying degrees in the original Restoration Plan, in order to maximize Greenwood Lake’s opportunities to obtain State and Federal funding for the design and implementation of watershed control measures, the WIP now explicitly correlates the nine elements to eight specific deliverables, which are as follows:

  1. Conduct a detailed in‐lake and watershed‐based water quality monitoring program and compare the data to that collected in 2004 and 2005 to document changes or shifts in water quality.
  2. Meet with the Township of West Milford, Passaic County and other stakeholders to
    inventory recently completed BMPs and other watershed management measures.
  3. Conduct a field‐based evaluation of the stormwater project completed since the original 319‐grant funded Restoration Plan.
  4. Conduct site assessments to identify other potential stormwater/watershed BMP projects.
  5. Conduct a field assessment of the Belchers Creek Corridor to identify potential Nonpoint Source Pollution Reduction Projects.
  6. Assemble the WIP with all the 9 elements fully satisfied.
  7. Schedule and implement stakeholder and public meetings to evaluate project status.
  8. Submit of final version of WIP to the NJDEP and present the findings and recommendations to the public.

This project was initiated in September 2018 and is projected for completion by September 2019. The Greenwood Lake Commission, serves as the inter‐State steward of the Greenwood Lake watershed, and is working closely with Princeton Hydro and the watershed stakeholders (Township of West Milford, Passaic County and others), to ensure the WIP is a holistic document.

Stay tuned for more Greenwood Lake updates as the WIP progresses. For more information about Princeton Hydro’s lake management projects and capabilities, or to discuss your project needs and goals, please contact us.
