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.

6 Tips To Prepare Your Pond For Spring

It’s officially time to say goodbye to winter and “spring” your pond out of hibernation mode. We’ve put together six tips for getting your pond ready for Spring and ensuring it remains healthy all year long.

1. SPRING CLEANING 

The first step in preparing your pond for Spring is to give it a thorough cleaning. Remove leaves, debris, and any surface algae that may have accumulated over the winter. For shallow ponds, you may be able to use a net or pond rake to remove debris and sediment from the bottom and along the perimeter of the pond.

2. INSPECT YOUR POND FOR DAMAGE

Inspect your pond, including berms, outlet structures, and trash racks for any damage that may have occurred over winter due to ice. If you observe any damage, we recommend contacting a professional right away. One of our engineers or certified pond managers can determine if the damage is superficial or requires more significant repairs. Also, if your pond is equipped with an aeration system, before starting it up, be sure to schedule a system inspection. A thorough inspection and proper start-up procedure will ensure the system remains fully and effectively operational for the entire summer.

3. PUT YOUR POND TO THE TEST

The routine testing of your pond’s water quality is an important part of preventing harmful algae growth, fish kills, and other problems. We recommend conducting a “Spring start up” water quality analysis of your pond. The resulting data will inform the management process and allow for the development of a pro-active, eco-friendly management plan. Maintaining your pond’s water quality helps to control nuisance aquatic species and promote environmental conditions supportive of a healthy and productive fishery.

4. AQUASCAPE YOUR SHORELINE

It’s important to check the pond’s shoreline for any signs of erosion. Mowing to the water line, especially in ponds that have fluctuating water levels, can lead to severe shoreline erosion. Eroding shorelines can be easily stabilized by planting native, riparian plants.

Deep-rooted, native emergent aquatic vegetation is able to tolerate alternating periods of exposure and dry inundation. The correct combination of native aquatic plants, emergent wetland plants, and transitional upland plants can correct or prevent chronic shoreline erosion problems. A properly planted (aquascaped) edge beautifies the shoreline, stabilizes erosion problems, creates fish and amphibian habitat, attracts pollinating species and a variety of birds, and decreases mosquito breeding.

5. CONSIDER INSTALLING AN AERATION SYSTEM

Sub-surface aeration systems eliminate stagnant water and keep your pond thoroughly mixed and properly circulated. These systems are the most cost-effective and energy-efficient way to maintain proper pond circulation. Proper aeration enhances fish habitat, minimizes the occurrence of algae blooms, and prevents mosquito breeding. It’s best to contact a certified lake/pond manager to first determine if aeration is the right solution for you. If it is, an aeration system tailored to your pond’s needs can be designed and installed.

6. HAVE AN ECOLOGICALLY BALANCED POND MANAGEMENT PLAN

There is more to pond management than weed and algae treatments alone. There is also a big difference between simple pond maintenance and ecologically-based pond management. A customized pond management plan acts as a “blueprint” that guides  proactive, long-term care for your pond.

Our certified lake and pond managers can assess the status of your pond and provide you with an environmentally holistic management plan that is based on the unique physical, hydrologic, chemical, and biological attributes of your pond. A management plan identifies the causes of your pond’s problems and provides you with the guidance needed to correct these problems. The results are far more environmentally sustainable than simple (and often unnecessary) reactive weed and algae treatments.

Efforts to Manage Hydrilla in Harveys Lake Prove Difficult but Effective

Collaboration between state agencies and local organizations in Luzerne County bring in grant money to determine Hydrilla infestation levels in Harveys Lake. Treatment efforts are scheduled for 2019.

Story provided by Princeton Hydro Senior Limnologist Michael Hartshorne, and originally published in the Pennsylvania iMapInvasives Fall 2018 Newsletter

Hydrilla (Hydrilla verticillata)

Hydrilla (Hydrilla verticillata) is a relatively new invasive plant in Pennsylvania with the first documented occurrence in 1989 in Adams County. Still, it was not until recently that lake managers, park rangers, and others in the natural resource field have turned their attention to this aggressive invader. Looking incredibly similar to our native waterweed (Elodea canadensis), hydrilla differs in that it is comprised of 4-8 whorled, toothed leaves in contrast to the smooth edged, 3-leaved whorl of E. canadensis.

 

Harveys Lake, located in the Borough of Harveys Lake (Luzerne County) is a large, deep glacial lake with limited littoral (i.e., shoreline) habitat. A significant body of work has been conducted at the lake with the original Phase I: Diagnostic-Feasibility Lake study conducted in 1992 and a Total Maximum Daily Load (TMDL) issued for phosphorus in 2002.

From 2002 to present, Princeton Hydro has assisted the Borough in the restoration of the lake with a heavy focus on stormwater best management practices (BMPs) supplemented by routine, in-lake water quality monitoring. The goal of the storm water/watershed-based efforts was to reduce the lake’s existing, annual total Hydrilla (Hydrilla verticillata) phosphorus load so it’s in full compliance with the established TMDL.

Mapped locations noted in 2014 and 2015 of hydrilla in Harveys Lake as documented in the Pennsylvania iMapInvasives database.

Over the last 15 years, the installation of these watershed-based projects has led to improved water quality conditions; specifically, phosphorus and algae concentrations have been reduced. While water quality conditions improved Harveys Lake, it was during one of the routine, summer water quality monitoring events conducted in July 2014 that a dense stand of hydrilla was noted at the Pennsylvania Fish and Boat Commission’s public boat launch. More than likely, the plant entered the lake as a “hitchhiker” on the boat or trailer being launched from this public boat launch by someone visiting the lake.

Since the initial identification and confirmation of the hydrilla, the Borough of Harveys Lake has worked in conjunction with the Harveys Lake Environmental Advisory Council, the Luzerne County Conservation District, the Pennsylvania Department of Environmental Protection, and Princeton Hydro to secure funding for additional surveys to determine the spatial extent and density of growth followed by an aggressive eradication plan.

Grant funds already allocated to Harveys Lake under the state’s Non-Point Source Pollution Program were used to conduct a detailed boat-based and diving aquatic plant survey of Harveys Lake to delineate the distribution and relative abundance of the hydrilla in 2014. During these surveys, the distribution of the hydrilla was found to be limited to the northern portion of the lake with the heaviest densities just off the boat launch with plants observed growing in waters 20-25 feet deep.

A follow-up survey had shown hydrilla coverage to increase from 38% of surveyed sites to 58% of sites in 2016 with hydrilla now present at the lake’s outlet area. Spatial coverage of hydrilla increased from approximately 50 acres in 2014 to 210 acres in 2016, an increase of 160 acres.

This map shows the 2018 proposed treatment area of Harvey’s Lake. Due to funding issues, treatment is now scheduled for 2019. The current hydrilla distribution encompasses the entire littoral zone of Harvey’s Lake.

In hopes of preventing hydrilla escaping into the lake’s outlet stream, the Borough of Harveys Lake funded an emergency treatment of the two-acre outlet area in 2016 utilizing the systemic herbicide Sonar® (Fluridone). A follow-up treatment of 159 acres was conducted in 2017, again utilizing the Fluridone-based systemic herbicide.

The next treatment, which will attempt to cover the majority of the littoral habitat covered by hydrilla, is scheduled for late spring/early summer of 2019. It should be noted that Sonar® is being applied at a low concentration that is effective at eradicating the hydrilla, but will not negatively impact desirable native plant species.

The treatments conducted to date have documented some reductions in the vegetative coverage of hydrilla as well as tuber production relative to the original plant surveys conducted in 2016. However, it is recognized that it will take multiple years of treatment to eradicate this nuisance plant from the lake, as well as a highly proactive, interactive program to educate residents as well as visitors to the lake in preventing the re-introduction of this or other invasive species to Harveys Lake.

 

The successful, long-term improvement of a lake or pond requires a proactive management approach that addresses the beyond simply reacting to weed and algae growth and other symptoms of eutrophication. Our staff can design and implement holistic, ecologically-sound solutions for the most difficult weed and algae challenges. Visit our website to learn more about Princeton Hydro’s lake management services: http://bit.ly/pondlake

“Floating Classroom” Launches into Lake Hopatcong

The Lake Hopatcong Foundation (LHF) recently launched its newest initiative – a floating classroom. The custom-built 40-foot education vessel, named ‘Study Hull’, gives students an interactive, hands-on education experience to explore Lake Hopatcong, learn about freshwater ecology, and learn how to protect the watershed.

During its maiden voyage field trip, which was held on May 21, fourth-graders from Nixon Elementary and Kennedy Elementary schools utilized the boat’s laboratory instruments to study water hydrology, temperatures, plankton, and dissolved oxygen levels. They performed a series of tests and experiments designed to help them learn about the general health of the lake. They used Secchi Disks to determine the depth to which light is able to penetrate the water’s surface. They also learned about runoff and nonpoint source pollutants, how to protect the lake’s water quality, and how to be good stewards of the water.

Princeton Hydro helped the LHF design a teaching curriculum on water quality.  Dr. Jack Szczepanski, Senior Aquatics Scientist, and Christopher L. Mikolajczyk, CLM, Senior Project Scientist, trained the staff and volunteers on the curriculum and demonstrated various water quality monitoring techniques that can be conducted with the students.

“We’re really proud to be a part of this exciting initiative,” said Mikolajczyk. “It’s really important to get kids interested in science at an early age and teach them about their surrounding environment – where their drinking water comes from, how it gets polluted, the impacts pollution has on the lake’s ecosystem, and what steps can be made to protect the lake’s water quality. We’re hoping the floating classroom field trip program will make a lasting, valuable impression with these kids.”

In the first year of operation it is expected that the Study Hull will host 1,000 fourth grade students. The long-term goal is to develop lesson plans for students in every grade from kindergarten through high school. Starting in July, the LHF is also offering the public tours of the floating classroom on Mondays at Hopatcong State Park.

The purchase of the floating classroom was made possible by financial support from USATODAY Network’s “A Community Thrives” program, which awarded the LHF with a $50,000 grant. The program recognizes three categories: arts and culture, education, and wellness. In each category, the first place winner received a $100,000 grant and the second and third place winners received $50,000 grants. The James P. Verhalen Family Foundation and the Szigethy Family also provided significant donations to help bring the floating classroom to life.

 

The LHF and Princeton Hydro are longtime partners. Starting back in 1983, Princeton Hydro’s Dr. Stephen Souza conducted the USEPA funded Diagnostic Feasibility study of the lake and then authored the Lake Hopatcong Restoration Plan. That document continues to be the backbone of why and how to restore the lake, manage the watershed, reduce pollutant loading, and address invasive aquatic plants and nuisance algae blooms.

Lake Hopatcong has one of the longest, continuous, long-term ecological databases in New Jersey; almost 30 years of consistently collected water quality data. The data is crucial in assessing the overall ecological health of the lake and proactively guiding its management, identifying and addressing emerging threats, documenting project success (a mandatory element of funding initiatives) and confirming compliance with New Jersey State Water Quality standards.

Princeton Hydro’s most recent work for Lake Hopatcong includes the implementation of green infrastructure stormwater management measures, installation of floating wetland islands to improve water quality, and invasive aquatic plant species management programs, community educational training, and surveys.

It is only given to a person who has shown the highest dedication to New York’s lakes and watersheds, assisted NYSFOLA in its mission, and produced exceptional performance in his or her field of endeavor.

In bestowing this award to Dr. Souza, NYSFOLA recognizes his accomplishments and efforts in the management and restoration of lakes throughout the State of New York and his support of the initiatives promoted by NYSFOLA. The award was presented at the NYSFOLA’s 35th annual conference, which was held on May 4th and 5th at the Fort William Henry Hotel in Lake George.

During his acceptance speech, Dr. Souza said, “I am truly humbled and appreciative to have even been considered worthy of this award.  In accepting the ‘Lake Tear of Clouds’ Award, I want to extend my deepest thanks to NYSFOLA, the NYSFOLA Board of Directors, Nancy Mueller (NYSFOLA Manager), and all of you here tonight.  It is people like yourselves, who advocate for clean lakes, that have made my career so rewarding. I would be remiss if I also did not take the time to thank my wife Maria and my family for their support over the years and of course the dedicated lake scientists that I have the pleasure to work with day in and day out at Princeton Hydro. That of course includes Dr. Fred Lubnow, who I have had the pleasure of working side-by-side with since 1992, Chris Mikolajczyk and Mike Hartshorne, both of whom are here tonight, and the rest of my Princeton Hydro colleagues.”

Dr. Souza first attended the NYSFOLA conference in 1985, and has been working to assess, restore and protect watersheds throughout the state of New York for over 35 years. Some of the notable projects managed by Dr. Souza over that time include projects conducted at Honeoye Lake, Sodus Bay, Greenwood Lake and Sleepy Hollow Lake. He is currently working with New York State Department of Environmental Conservation on a major statewide harmful algae bloom (HAB) management effort.

“We thank you for your longtime support of NYSFOLA and our member lake association, Steve,” said Nancy J. Mueller, Manager. “And, we congratulate Princeton Hydro on its 20th anniversary.”

New York Hosts Harmful Algal Blooms Summit

The Western New York Harmful Algal Blooms (HABs) Summit, the last of four Statewide HABs summits, was held last month in Rochester, NY. The summits kicked off Governor Cuomo’s $65 million initiative to protect the NY State’s lakes, ponds and reservoirs, and those that rely on these waterbodies for recreation and drinking water, from the ecological and health impacts associated with HABs.

“Protecting New York’s natural resources is key to ensuring residents have access to safe water, and through this collaborative summit, we are addressing the growing threat of harmful algal blooms,” said Governor Cuomo in a recent press release.

Each regional summit involved a day-long session of expert presentations and panel discussions on a variety of HAB related topics, and culminated in an evening session, which was open to the public and provided community members an opportunity to learn more about the Governor’s initiative and pose questions to NYSDEC about HABs and the management of HABs. The evening sessions were available to view via a live online stream as well.

For each summit, the Governor invited regional experts to participate along with NYSDEC and Department of Health experts. The experts were brought together to initiate the development of tailored HAB action plans. Although the focus was placed on the management of Governor Cuomo’s 12 priority waterbodies, the goal was to identify HAB management plans applicable for all of the State’s waterbodies, large or small. The discussions that evolved through the four summits set the stage to inform decisions related to preventing and properly responding to HABs across the state.

Participating by the invitation of Governor Cuomo and the NYSDEC in last month’s Western New York Summit were:

  • Dr. Steve Souza, Princeton Hydro
  • Art DeGaetano, Cornell University
  • Christopher Gobler, SUNY Stony Brook
  • Dave Matthews, Upstate Freshwater Institute
  • Greg Boyer, SUNY ESF
  • Nelson Hairston, Cornell University
  • Sally Flis, The Fertilizer Institute
  • Tim Davis, Bowling Greene State University, Ohio

During the Western New York Summit, Dr. Souza, Princeton Hydro co-founder, provided insight on the causes of HABs and, in particular, discussed the management techniques that have been successfully implemented by Princeton Hydro to combat the onset and mitigate the impacts of HABs.

About Governor Cuomo’s Harmful Algal Blooms program:
Governor Cuomo’s program builds on New York’s $2.5 billion Clean Water Infrastructure Act investments in clean water infrastructure and water quality protection. The Harmful Algal Blooms initiative is supported with funds from both the Clean Water Infrastructure Act and the $300 million Environmental Protection Fund. Through the Governor’s leadership, New York has developed the most comprehensive HABs outreach and monitoring programs in the country, led by DEC sampling of ambient waters across the state and DOH sampling at regulated beaches and public water systems.
