2019 Successes: A Year in Review

Over the last two decades, we’ve restored many miles of rivers, improved water quality in hundreds of ponds and lakes, and enhanced thousands of acres of ecosystems in the Mid-Atlantic and New England regions. In 2019, we had our best year yet. As we reflect back on 2019 and set our sights on 2020, we have many successes to celebrate:

1. We Designed the Largest Dam Removal in New Jersey.

The century-old Columbia Dam was removed and fish passage was restored on the 42-mile long Paulins Kill river, an important tributary to the Delaware River in northwestern New Jersey. On Earth Day 2019, just two months after the river finally flowed free, we were thrilled to discover the return of American shad upstream for the first time in over 100 years.

2. We Conceptualized Six Sites Along the Hudson River for Habitat Restoration.

Our team completed a feasibility study for the U.S. Army Corps of Engineers (USACE), which identified and conceptualized restoration opportunities at six key sites. For this Hudson River Habitat Restoration Integrated Feasibility Study and Environmental Assessment, Princeton Hydro collected and analyzed data, reviewed existing conditions, and drafted conceptual restoration designs. Our final report was just highlighted by USACE at the 2019 Planning Community of Practice (PCoP) national conference at the Kansas City District as an example of a successfully implemented Ecosystem Restoration Planning Center of Expertise (ECO-PCX) project.

3. National and Regional News Outlets Featured Princeton Hydro Harmful Algal Bloom Experts.

After a record-breaking number of HABs broke out in lakes across the region, our Aquatics Team was called upon for their expertise and insights into why the outbreak was happening, what could be done to treat it, and what preventative actions will lessen the likelihood of future outbreaks. In addition to being featured in various regional news outlets covering the HABs topic, Princeton Hydro experts were featured in the New York Times and the Washington Post for their leadership at the largest lake in New Jersey, Lake Hopatcong.

4. Our Staff Presented, Exhibited, and Attended Over 50 Events.

From galas to environmental conferences and river restoration tours to college courses, the Princeton Hydro team participated in more than 50 events throughout 2019. Dr. Clay Emerson, PE taught a Green Infrastructure Stormwater Management Course at Montclair University. Kelsey Mattison, Marketing Coordinator, presented at the 3rd Annual New Jersey Watershed Conference. And, at the New Jersey Land Conservation Rally, we had three presentations on citizen science, marketing strategy, and lake stewardship. Various team members rolled up their sleeves to volunteer to plant trees at Exton Park on Arbor Day, build a rain garden in Clawson Park, and restore eroding shoreline in Point Pleasant. Stayed tuned for more in 2020!

5. We’re Restoring the Northernmost Freshwater Tidal Marsh on the Delaware River.

Mercer County’s John A. Roebling Memorial Park is home to the northernmost freshwater tidal marsh on the Delaware River, Abbott Marshland, an area containing valuable habitat for many rare species. Unfortunately, the area has experienced a significant amount of loss and degradation, partially due to the introduction of the invasive Phragmites australis. The Princeton Hydro team proudly removed this invasive species and is restoring the marsh to enhance plant diversity, wildlife habitat, and water quality.

6. We Upcycled Christmas Trees to Stabilize an Eroding Shoreline for the First Time in NJ.

To prevent further erosion at the Slade Dale Sanctuary in Point Pleasant, dozens of volunteers helped stabilize the shoreline using recycled Christmas trees, a technique never been done before in New Jersey. The 13-acre Slade Dale Sanctuary is an important part of the local ecosystem and much work is being done there to restore the marsh and enhance the ecological function and integrity of the preserve. Princeton Hydro developed a conceptual and engineering design using living shoreline features, including tree vane structures to attenuate wave action, foster sediment accretion, and reduce erosion.

7. Princeton Hydro Earned Three Prestigious Awards.

The Friends of the Presumpscot River awarded Laura Wildman, P.E., with its “Chief Polin Award” for her accomplishments and efforts in bringing life back to the Presumpscot River and rivers across the nation. The New Jersey Highlands Coalition honored Founding Principal Dr. Stephen Souza with a Lifetime Achievement Award, touting his dedication to preserving and protecting New Jersey’s watersheds and natural resources. And, our Pin Oak Forest and Wetland Restoration project earned the “Land Ethics Award of Merit” from Bowman’s Hill Wildflower Preserve for its remarkable restoration achievements.

8. We’re Converting an Urban, Flood-Prone Industrial Site into a Thriving Public Park.

Along the Third River and Spring Brook, two freshwater tributaries of the Passaic River, a former industrial site that is highly-disturbed and flood-prone is being transformed into a thriving public park. The team broke ground on this important ecological restoration and urban wetland creation project in March and the restoration work continues. Princeton Hydro is serving as the ecological engineer to Bloomfield Township providing a variety of services and expertise.

9. Princeton Hydro Welcomed 12 New Staff and Added Two Key Positions.

As part of the expansion of our growing business, Princeton Hydro added 12 team members with expertise and qualifications in a variety of fields. In July, we announced a new executive position in the firm, Chief Operating Officer, to which Kevin M. Yezdimer, P.E. was appointed. We also created an internal Human Resources Department and hired Samara McAuliffe as Employee Relations Manager. Princeton Hydro has grown from a small, four-person idea operating out of a living room to a 65+ person qualified Small Business with six office locations in the Northeast region.

10. New Year, New Locations!

We’re moving on up! In 2019, we moved our D.C. Regional Office down the road from Annapolis, MD to Bowie, MD expanding into a larger office space to accommodate our staff growth and providing opportunity for more growth in the region. And, in late 2019, through our strategic partnership with Merestone Consulting, we opened a sixth office in Wilmington, Delaware. Stay tuned for more information!

Dr. Fred Lubnow of Princeton Hydro Featured in Magazine Article on Chautauqua Lake

The U.S. is home to thousands of lakes both natural and manmade. Lakes are incredibly important features in the landscape that provide numerous beneficial services, including domestic water supply, hydro-electric power, agricultural water supply, recreation, and tourism. They also provide essential habitat for fish, wildlife and aquatic organisms.

Lakes are complex and dynamic systems, each situated in a unique landscape context. Maintaining the ecological health of a lake is no easy feat. A lot goes on behind the scenes to maintain water quality and a balanced lake ecosystem. Successful, long-term lake management requires a proactive approach that addresses the causes of its water quality problems rather than simply reacting to weed and algae growth and other symptoms of eutrophication.

Chautauqua Magazine recently published an article about the science behind the management of Chautauqua Lake, which features our Director of Aquatic Programs Dr. Fred Lubnow. We’ve included an excerpt below. Click here to view the full article and photos:

Dr. Fred Lubnow is a scientist and director of aquatic programs at Princeton Hydro, a consulting organization based in Exton, Pennsylvania, that is often called on to support lake and watershed regions that want to develop a long-term plan for lake conservation.

He says that while his firm focuses on the development of data and intelligence to inform decision making in regard to freshwater ecosystems, his work is really about coalition building.

“As a scientist and a consultant, you learn over time that you are building a coalition stakeholders and determining what we can agree on to help everyone in the community,” Lubnow said.

Ten years ago, Princeton Hydro was hired to do some stream and inlet monitoring for various stakeholders at Chautauqua Lake. More recently, they’ve been contracted to conduct third-party monitoring of the impacts of the Spring 2019 herbicide applications in the south basin of Chautauqua Lake…

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.

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.

Four Ways Climate Change Can Affect Your Lake

The Local Effects of Climate Change Observed Through our Community Lakes

Climate change is an enormous concept that can be hard to wrap your head around. It comes in the form of melting ice caps, stronger storms, and more extreme seasonal temperatures (IPCC, 2018). If you’re an avid angler, photographer, swimmer, boater, or nature enthusiast, it’s likely that because of climate change you’ll bear witness to astonishing shifts in nature throughout the greater portion of your lifetime. This is especially true with respect to lakes.

2015-07-07-10-01-20

Lakes are living laboratories through which we can observe the local effects of climate change in our own communities. Lake ecosystems are defined by a combination of various abiotic and biotic factors. Changes in hydrology, water chemistry, biology, or physical properties of a lake can have cascading consequences that may rapidly alter the overall properties of a lake and surrounding ecosystem. Most of the time the results are negative and the impacts severe.

“Managing loads of phosphorous in watersheds is even more important as the East Coast becomes increasingly warmer and wetter thanks to climate change,” said Dr. Fred Lubnow, Director of Aquatics in a recent NJ.com interview. “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.”

Recognizing and monitoring the changes that are taking place locally brings the problems of climate change closer to home, which can help raise awareness and inspire environmentally-minded action.

We put together a list of four inter-related, climate change induced environmental impacts that can affect lakes and lake communities:

1. Higher Temperatures = Shifts in Flora and Fauna Populations

The survival of many lake organisms is dependent on the existence of set temperature ranges and ample oxygen levels. The amount of dissolved oxygen (DO) present in a lake is a result of oxygen diffusion from the atmosphere and its production by algae and aquatic plants via photosynthesis. An inverse relationship exists between water temperature and DO concentrations. Due to the physical properties of water, warmer water holds less DO than cooler water.

This is not good news for many flora and fauna, such as fish that can only survive and reproduce in waters of specific temperatures and DO levels. Lower oxygen levels can reduce their ability to feed, spawn and survive. Populations of cold water fish, such as brown trout and salmon, will be jeopardized by climate change (Kernan, 2015).

358-001-carp-from-churchvilleAlso, consider the effects of changing DO levels on fish that can tolerate these challenging conditions. They will thrive where others struggle, taking advantage of their superior fitness by expanding their area of colonization, increasing population size, and/or becoming a more dominant species in the ecosystem. A big fish in a little pond, you might say. Carp is a common example of a thermo-tolerant fish that can quickly colonize and dominate a lake’s fishery, in the process causing tremendous ecological impact (Kernan, 2010).

2. Less Water Availability = Increased Salinity

Just as fish and other aquatic organisms require specific ranges of temperature and dissolved oxygen to exist, they must also live in waters of specific salinity. Droughts are occurring worldwide in greater frequency and intensity. The lack of rain reduces inflow and higher temperatures promote increased evaporation. Diminishing inflow and dropping lake levels are affecting some lakes by concentrating dissolved minerals and increasing their salinity.

Studies of zooplankton, crustaceans and benthic insects have provided evidence of the consequences of elevated salinity levels on organismal health, reproduction and mortality (Hall and Burns, 2002; Herbst, 2013; Schallenberg et al., 2003). While salinity is not directly related to the fitness or survival rate of all aquatic organisms, an increase in salinity does tend to be stressful for many.

3. Nutrient Concentrations = Increased Frequency of Harmful Algal Blooms

Phosphorus is a major nutrient in determining lake health. Too little phosphorus can restrict biological growth, whereas an excess can promote unbounded proliferation of algae and aquatic plants.

before_strawbridgelake2If lake or pond water becomes anoxic at the sediment-water interface (meaning the water has very low or completely zero DO), phosphorus will be released from the sediment. Also some invasive plant species can actually “pump” phosphorus from the sediments and release this excess into the water column (termed luxurious uptake). This internally released and recycled sedimentary phosphorus can greatly influence lake productivity and increase the frequency, magnitude and duration of algae blooms. Rising water temperatures, declining DO and the proliferation of invasive plants are all outcomes of climate change and can lead to increases in a lake’s phosphorus concentrations and the subsequent growth and development of algae and aquatic plants.

Rising water temperatures significantly facilitate and support the development of cyanobacteria (bluegreen algae) blooms. These blooms are also fueled by increasing internal and external phosphorus loading. At very high densities, cyanobacteria may attain harmful algae bloom (HAB) proportions. Elevated concentrations of cyanotoxins may then be produced, and these compounds seriously impact the health of humans, pets and livestock.

rain-garden-imagePhosphorus loading in our local waterways also comes from nonpoint sources, especially stormwater runoff. Climate change is recognized to increase the frequency and magnitude of storm events. Larger storms intensify the mobilization and transport of pollutants from the watershed’s surrounding lakes, thus leading to an increase in nonpoint source loading. Additionally, larger storms cause erosion and instability of streams, again adding to the influx of more phosphorus to our lakes. Shifts in our regular behaviors with regards to fertilizer usage, gardening practices and community clean-ups, as well as the implementation of green infrastructure stormwater management measures can help decrease storm-related phosphorus loading and lessen the occurrence of HABs.

4. Cumulative Effects = Invasive Species

A lake ecosystem stressed by agents such as disturbance or eutrophication can be even more susceptible to invasive species colonization, a concept coined “invasibility” (Kernan, 2015).

For example, imagine that cold water fish species A has experienced a 50% population decrease as a result of warming water temperatures over ten years. Consequently, the fish’s main prey, species B, has also undergone rapid changes in its population structure. Inversely, it has boomed without its major predator to keep it in check. Following this pattern, the next species level down – species B’s prey, species C – has decreased in population due to intense predation by species B, and so on. Although the ecosystem can potentially achieve equilibrium, it remains in a very unstable and ecologically stressful state for a prolonged period of time. This leads to major changes in the biotic assemblage of the lake and trickle-down changes that affect its recreational use, water quality and aesthetics.

• • •

Although your favorite lake may not experience all or some of these challenges, it is crucial to be aware of the many ways that climate change impacts the Earth. We can’t foresee exactly how much will change, but we can prepare ourselves to adapt to and aid our planet. How to start? Get directly involved in the management of your lake and pond. Decrease nutrient loading and conserve water. Act locally, but think globally. Get out and spread enthusiasm for appreciating and protecting lake ecosystems. Also, check out these tips for improving your lake’s water quality.

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.

Belcher's Creek at Edgecumb and Glencross

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.
