Funded through Section 319(h) of the federal Clean Water Act and administered by the DEP's Watershed and Land Management Program, these grants were awarded to municipalities, nonprofit organizations, and academic institutions across the state. Princeton Hydro is proud to be a partner on five of the 17 funded projects. Our contributions vary by project and encompass activities such as engineering design, water quality assessment, watershed-based planning, and technical support for implementing stormwater and habitat restoration measures. Let's take a deeper look at these collaborative efforts: 1. The Watershed Institute – Watershed-Based Planning for Assunpink Creek The Watershed Institute received $205K in 319(h) grant funding to develop a watershed-based plan for the Assunpink Creek watershed, located within the Raritan River Basin. This watershed spans 11 municipalities across two counties, where varied landscapes and demographics share common challenges such as localized flooding, stormwater management, and water quality degradation, highlighting the need for a coordinated, watershed-wide, science-driven approach. The plan will evaluate pollution sources and identify large-scale restoration opportunities, including green infrastructure and riparian buffer restoration, to improve water quality and reduce flooding. It will also assess the cost, feasibility, and pollutant reduction potential of proposed measures to ensure practical implementation. Princeton Hydro supported the Institute in developing the grant proposal and planning framework, leveraging our expertise in watershed-based planning to prioritize nature-based solutions that address both water quality and climate resilience. This initiative represents a critical step toward regional collaboration, enabling upstream and downstream communities to work together on strategies that strengthen watershed health, protect public safety, and build long-term resilience. 2. Lake Hopatcong Commission – Watershed-Based Stormwater BMPs The Lake Hopatcong Commission (LHC) was awarded $366K to retrofit an existing stormwater detention basin between King Road and Mount Arlington Boulevard in Roxbury Township. This retrofit is part of a larger Watershed Implementation Plan that Princeton Hydro developed in collaboration with LHC, which prioritizes nutrient reduction and stormwater management strategies across the Lake Hopatcong watershed. Over the past several years, LHC has actively implemented multiple elements of this plan to address harmful algal blooms (HABs) and improve water quality. For this project, Princeton Hydro is providing engineering design and technical oversight to transform the existing basin into a green stormwater infrastructure system that slows, captures, and naturally treats runoff before it enters King Cove. The design incorporates native vegetation, invasive species management, and erosion control measures to stabilize soils and filter pollutants, reducing nutrient loading, which is one key driver of HABs. Public outreach and pre- and post-construction water quality monitoring will ensure performance tracking and measurable improvements. This basin retrofit represents a critical step in a coordinated, science-based approach to restoring ecological health and water quality in New Jersey’s largest lake. 3. Cozy Lake, Jefferson Township – Addressing Emerging Contaminants Jefferson Township received $350K in grant funding to develop an Emerging Contaminants Management Plan for Cozy Lake, focusing on cyanotoxins and HABs. Cozy Lake is a 28-acre waterbody within a 1,152-acre sub-watershed that includes both forested (60%) and developed (29%) land. The lake is fed by the Rockaway River at its northern end and a smaller southeastern inlet, with outflow through a dam on the western edge. The shoreline is primarily residential lawn with minimal emergent wetlands, and several inlets and rock-lined drainage ditches exhibit erosion and lack slope protection, contributing to sediment loading. Princeton Hydro provided early technical input to shape this innovative project with the creation of a comprehensive Jefferson Township Lake and Watershed Restoration and Protection Plan. As part of the plan, Princeton Hydro made recommendations for Cozy Lake, which included enhancing shoreline buffers with native vegetation and installing living shorelines at select properties to stabilize soils, filter stormwater and reduce nutrient loading, improve habitat quality, and enhance community access. These measures, combined with in-lake monitoring and proactive management strategies, will help mitigate HABs and protect ecological and public health. 4. Rockaway Township – Watershed-Based Green Infrastructure Rockaway Township received $399K in grant funding to implement elements of its Watershed Implementation Plan, focusing on green infrastructure stormwater management and nutrient reduction to improve water quality. The project will retrofit the municipal complex by converting a rock-lined drainage swale into a vegetated swale with a bioretention basin, designed to filter stormwater runoff and reduce nonpoint source pollutants entering Fox’s Pond and Fox Brook. Princeton Hydro played a key role in developing the Watershed Implementation Plan, which encompasses 11 private lakes within the Rockaway River watershed, prioritizing critical locations for intervention and designing cost-effective green infrastructure BMPs. This regional approach aligns with strategies recommended by NJDEP and the Highlands Council. The plan included a comprehensive watershed-based assessment to identify and quantify factors contributing to eutrophication, evaluate management measures, estimate costs, and establish an implementation schedule. Princeton Hydro authored the final report, which guided the Township in applying for the Section 319(h) grant and now informs the design and construction of green stormwater infrastructure that will deliver measurable water quality improvements while supporting ecological restoration goals. 5. Green Trust Alliance – Green Infrastructure and Community Engagement Green Trust Alliance (GTA), a nationally accredited land trust and public charity dedicated to accelerating large-scale conservation, received $1.39 million in NJDEP funding to implement green infrastructure improvements at Pinelands Regional High School in Tuckerton, New Jersey. This initiative targets the Tuckerton Creek watershed, which drains into Tuckerton Creek and ultimately flows into Barnegat Bay—a critical estuary spanning 33 municipalities in Ocean County and four in Monmouth County. The retrofit will transform the school’s stormwater detention basin into a multi-functional system that mimics natural hydrology, enhances flow control, and improves water quality locally and in the larger Barnegat Bay watershed. Working with GTA and GreenVest, Princeton Hydro is serving as the design engineer, applying nature-based engineering and ecological restoration techniques to intercept, evapotranspire, and infiltrate stormwater runoff at its source. In addition to its technical objectives, the effort includes a strong community engagement component and an educational platform for students. By bringing green infrastructure into the school environment, the initiative provides hands-on experience with water resources, stormwater management, and ecological engineering, help to build STEM skills while fostering a deeper connection to the surrounding landscape and an understanding of how natural systems work together to support environmental and community health. Princeton Hydro also assisted several of these partners in developing successful NJDEP Section 319(h) grant applications, providing technical documentation, conceptual designs, and pollutant load reduction estimates to strengthen the proposals. To date, the Murphy Administration has awarded more than $33M in Water Quality Restoration grants to improve the health of waterways in all corners of the state.

Held via Microsoft Teams and free to attend, this year’s summit embraced the theme “Kicking the HAB-it Together: Collaborating to Get Ahead of HABs”—a fitting reflection of the event’s focus on moving away from crisis-driven responses and toward proactive, long-term solutions for managing HABs. The summit brought together a diverse audience of local, state, and federal government representatives, environmental commissions, watershed associations, nonprofits, academic researchers, lake management professionals, and community members united by a shared goal: to better understand, prevent, and manage the impacts of HABs. With presentations spanning public health, policy, science, and on-the-ground solutions, the program set the stage for a day of insightful discussion and knowledge-sharing. The day kicked off with opening remarks and presentations from NJDEP representatives and the Montgomery Township Health Department, who provided updates on state-level HAB response efforts and local public health perspectives. The morning session also featured a technical keynote address from Dr. Wayne Carmichael, Professor Emeritus at Wright State University and a nationally recognized pioneer in HAB research. Dr. Carmichael offered a comprehensive national overview of the current HAB landscape, emerging threats, and the evolving science behind bloom detection, health risk assessment, and mitigation strategies. His presentation underscored the importance of cross-sector collaboration in tackling this growing environmental challenge. In the afternoon, the focus shifted to collaboration and preparedness. A panel discussion titled “Getting Ahead of the Crisis: Prevention vs. Response” included a range of voices, including NJDEP leadership, municipal representatives, and advocacy groups like The Watershed Institute. Panelists discussed how coordinated efforts, regulatory tools, and community engagement can help prevent the conditions that lead to HABs, rather than merely responding after blooms occur. The final portion of the summit highlighted innovative management strategies. Presentations covered topics like choosing practical solutions for HABs and restoration case studies. Princeton Hydro’s own Pat Rose, Aquatics Project Manager and Environmental Scientist, was among the expert speakers. Pat presented on a cutting-edge research and development initiative funded by the U.S. Army Corps of Engineers' Engineer Research and Development Center (ERDC). His talk explored both proactive and reactive treatment strategies designed to control near-shore HABs at Lake Hopatcong, New Jersey's largest lake, in a cost-effective and sustainable manner.

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 (e.g., heavy rains followed by hot, sunny days), these organisms can rapidly increase to form HABs. Climate change is leading to more frequent, more intense rainstorms that drive run-off pollutants into waterways, coupled with more hot days that increase the water temperature, creating the ideal environment for HABs to proliferate. In recent years, HABs have begun to appear in more places, earlier in the summer. The New Jersey Governor’s HABs Initiative was launched in 2019 after lakes throughout NJ (and the entire Continental U.S.) suffered from HAB outbreaks, which caused local and county health agencies to close off all beaches and issue advisories. These unprecedented conditions had significant negative impacts on lake-related ecological, recreational, and economic resources. The Governor’s initiative designated $13 million in funding to local communities for HABs reduction/prevention; established the HABs expert team, which includes Princeton Hydro Senior Technical Director, Ecological Services Dr. Fred Lubnow; and coordinated annual HABs summits in order to encourage continued community education and discussion.

The New Jersey Department of Environmental Protection (NJDEP) recently announced $8 million in Water Quality Restoration Grants to support projects that reduce nonpoint source pollution, mitigate harmful algal blooms, restore riparian areas, and enhance watershed and climate resilience. Funded through Section 319(h) of the federal Clean Water Act and administered by the DEP's Watershed and Land Management Program, these grants were awarded to municipalities, nonprofit organizations, and academic institutions across the state.
Princeton Hydro is proud to be a partner on five of the 17 funded projects. Our contributions vary by project and encompass activities such as engineering design, water quality assessment, watershed-based planning, and technical support for implementing stormwater and habitat restoration measures. Let's take a deeper look at these collaborative efforts:
The Watershed Institute received $205K in 319(h) grant funding to develop a watershed-based plan for the Assunpink Creek watershed, located within the Raritan River Basin. This watershed spans 11 municipalities across two counties, where varied landscapes and demographics share common challenges such as localized flooding, stormwater management, and water quality degradation, highlighting the need for a coordinated, watershed-wide, science-driven approach.
The plan will evaluate pollution sources and identify large-scale restoration opportunities, including green infrastructure and riparian buffer restoration, to improve water quality and reduce flooding. It will also assess the cost, feasibility, and pollutant reduction potential of proposed measures to ensure practical implementation. Princeton Hydro supported the Institute in developing the grant proposal and planning framework, leveraging our expertise in watershed-based planning to prioritize nature-based solutions that address both water quality and climate resilience. This initiative represents a critical step toward regional collaboration, enabling upstream and downstream communities to work together on strategies that strengthen watershed health, protect public safety, and build long-term resilience.
The Lake Hopatcong Commission (LHC) was awarded $366K to retrofit an existing stormwater detention basin between King Road and Mount Arlington Boulevard in Roxbury Township. This retrofit is part of a larger Watershed Implementation Plan that Princeton Hydro developed in collaboration with LHC, which prioritizes nutrient reduction and stormwater management strategies across the Lake Hopatcong watershed. Over the past several years, LHC has actively implemented multiple elements of this plan to address harmful algal blooms (HABs) and improve water quality.
For this project, Princeton Hydro is providing engineering design and technical oversight to transform the existing basin into a green stormwater infrastructure system that slows, captures, and naturally treats runoff before it enters King Cove. The design incorporates native vegetation, invasive species management, and erosion control measures to stabilize soils and filter pollutants, reducing nutrient loading, which is one key driver of HABs. Public outreach and pre- and post-construction water quality monitoring will ensure performance tracking and measurable improvements. This basin retrofit represents a critical step in a coordinated, science-based approach to restoring ecological health and water quality in New Jersey’s largest lake.
Jefferson Township received $350K in grant funding to develop an Emerging Contaminants Management Plan for Cozy Lake, focusing on cyanotoxins and HABs. Cozy Lake is a 28-acre waterbody within a 1,152-acre sub-watershed that includes both forested (60%) and developed (29%) land. The lake is fed by the Rockaway River at its northern end and a smaller southeastern inlet, with outflow through a dam on the western edge.
The shoreline is primarily residential lawn with minimal emergent wetlands, and several inlets and rock-lined drainage ditches exhibit erosion and lack slope protection, contributing to sediment loading. Princeton Hydro provided early technical input to shape this innovative project with the creation of a comprehensive Jefferson Township Lake and Watershed Restoration and Protection Plan. As part of the plan, Princeton Hydro made recommendations for Cozy Lake, which included enhancing shoreline buffers with native vegetation and installing living shorelines at select properties to stabilize soils, filter stormwater and reduce nutrient loading, improve habitat quality, and enhance community access. These measures, combined with in-lake monitoring and proactive management strategies, will help mitigate HABs and protect ecological and public health.
Rockaway Township received $399K in grant funding to implement elements of its Watershed Implementation Plan, focusing on green infrastructure stormwater management and nutrient reduction to improve water quality. The project will retrofit the municipal complex by converting a rock-lined drainage swale into a vegetated swale with a bioretention basin, designed to filter stormwater runoff and reduce nonpoint source pollutants entering Fox’s Pond and Fox Brook.
Princeton Hydro played a key role in developing the Watershed Implementation Plan, which encompasses 11 private lakes within the Rockaway River watershed, prioritizing critical locations for intervention and designing cost-effective green infrastructure BMPs. This regional approach aligns with strategies recommended by NJDEP and the Highlands Council. The plan included a comprehensive watershed-based assessment to identify and quantify factors contributing to eutrophication, evaluate management measures, estimate costs, and establish an implementation schedule. Princeton Hydro authored the final report, which guided the Township in applying for the Section 319(h) grant and now informs the design and construction of green stormwater infrastructure that will deliver measurable water quality improvements while supporting ecological restoration goals.
Green Trust Alliance (GTA), a nationally accredited land trust and public charity dedicated to accelerating large-scale conservation, received $1.39 million in NJDEP funding to implement green infrastructure improvements at Pinelands Regional High School in Tuckerton, New Jersey. This initiative targets the Tuckerton Creek watershed, which drains into Tuckerton Creek and ultimately flows into Barnegat Bay—a critical estuary spanning 33 municipalities in Ocean County and four in Monmouth County. The retrofit will transform the school’s stormwater detention basin into a multi-functional system that mimics natural hydrology, enhances flow control, and improves water quality locally and in the larger Barnegat Bay watershed.
Working with GTA and GreenVest, Princeton Hydro is serving as the design engineer, applying nature-based engineering and ecological restoration techniques to intercept, evapotranspire, and infiltrate stormwater runoff at its source. In addition to its technical objectives, the effort includes a strong community engagement component and an educational platform for students. By bringing green infrastructure into the school environment, the initiative provides hands-on experience with water resources, stormwater management, and ecological engineering, help to build STEM skills while fostering a deeper connection to the surrounding landscape and an understanding of how natural systems work together to support environmental and community health.
Princeton Hydro also assisted several of these partners in developing successful NJDEP Section 319(h) grant applications, providing technical documentation, conceptual designs, and pollutant load reduction estimates to strengthen the proposals.

On April 9, experts and stakeholders from across the country gathered virtually for the New Jersey Department of Environmental Protection’s (NJDEP) 6th Annual Harmful Algal Bloom (HAB) Summit. Held via Microsoft Teams and free to attend, this year’s summit embraced the theme “Kicking the HAB-it Together: Collaborating to Get Ahead of HABs”—a fitting reflection of the event’s focus on moving away from crisis-driven responses and toward proactive, long-term solutions for managing HABs.
The summit brought together a diverse audience of local, state, and federal government representatives, environmental commissions, watershed associations, nonprofits, academic researchers, lake management professionals, and community members united by a shared goal: to better understand, prevent, and manage the impacts of HABs. With presentations spanning public health, policy, science, and on-the-ground solutions, the program set the stage for a day of insightful discussion and knowledge-sharing.
The day kicked off with opening remarks and presentations from NJDEP representatives and the Montgomery Township Health Department, who provided updates on state-level HAB response efforts and local public health perspectives. The morning session also featured a technical keynote address from Dr. Wayne Carmichael, Professor Emeritus at Wright State University and a nationally recognized pioneer in HAB research. Dr. Carmichael offered a comprehensive national overview of the current HAB landscape, emerging threats, and the evolving science behind bloom detection, health risk assessment, and mitigation strategies. His presentation underscored the importance of cross-sector collaboration in tackling this growing environmental challenge.
In the afternoon, the focus shifted to collaboration and preparedness. A panel discussion titled “Getting Ahead of the Crisis: Prevention vs. Response” included a range of voices, including NJDEP leadership, municipal representatives, and advocacy groups like The Watershed Institute. Panelists discussed how coordinated efforts, regulatory tools, and community engagement can help prevent the conditions that lead to HABs, rather than merely responding after blooms occur.
The final portion of the summit highlighted innovative management strategies. Presentations covered topics like choosing practical solutions for HABs and restoration case studies. Princeton Hydro’s own Pat Rose, Aquatics Project Manager and Environmental Scientist, was among the expert speakers. Pat presented on a cutting-edge research and development initiative funded by the U.S. Army Corps of Engineers' Engineer Research and Development Center (ERDC). His talk explored both proactive and reactive treatment strategies designed to control near-shore HABs at Lake Hopatcong, New Jersey's largest lake, in a cost-effective and sustainable manner.
If you weren’t able to attend the summit live, don’t worry—you can now watch the full recording on the NJDEP YouTube channel:
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 (e.g., heavy rains followed by hot, sunny days), these organisms can rapidly increase to form HABs. Climate change is leading to more frequent, more intense rainstorms that drive run-off pollutants into waterways, coupled with more hot days that increase the water temperature, creating the ideal environment for HABs to proliferate. In recent years, HABs have begun to appear in more places, earlier in the summer.
The New Jersey Governor’s HABs Initiative was launched in 2019 after lakes throughout NJ (and the entire Continental U.S.) suffered from HAB outbreaks, which caused local and county health agencies to close off all beaches and issue advisories. These unprecedented conditions had significant negative impacts on lake-related ecological, recreational, and economic resources. The Governor’s initiative designated $13 million in funding to local communities for HABs reduction/prevention; established the HABs expert team, which includes Princeton Hydro Senior Technical Director, Ecological Services Dr. Fred Lubnow; and coordinated annual HABs summits in order to encourage continued community education and discussion.

New Jersey Department of Environmental Protection (NJDEP) Commissioner Shawn M. LaTourette presented the City of Lambertville with the NJDEP "Our Water’s Worth It" award. The award ceremony, held at a stormwater infrastructure improvement project site behind the Lambertville Firehouse, celebrated the Lambertville's commitment to improving stormwater management, addressing flooding, protecting local waterbodies, increasing storm resilience, and mitigating the impacts of climate change.
In a press release announcing the award, Commissioner LaTourette said, “Modernization of stormwater management strategies and infrastructure is critical to mitigating flooding that is severely impacting communities across New Jersey. My DEP colleagues and I applaud Lambertville for paving the way for others to follow in managing stormwater more effectively.”
The "Our Water’s Worth It" campaign, launched by NJDEP earlier this year, aims to raise awareness about the importance of protecting New Jersey’s water resources. The campaign highlights municipalities, water systems, and others who go above and beyond in water resource management and infrastructure improvements. Lambertville’s forward-thinking approach to stormwater management, particularly in meeting permitting requirements ahead of schedule, earned the city this well-deserved recognition.
At Princeton Hydro, we are proud to support the City of Lambertville in its stormwater management initiatives. Our team has been working closely with Lambertville to design projects that not only mitigate flooding but also enhance the surrounding natural environment.
During the award ceremony, Senior Project Manager and Professional Engineer, Sean Walsh, PE, said: “We are honored to be here today alongside NJDEP and the City of Lambertville celebrating Lambertville's remarkable achievement in receiving the 'Our Water's Worth It' trophy. It's particularly meaningful that this recognition comes during Climate Week, underscoring the importance of local action in addressing global environmental challenges.”
Earlier this year, the Princeton Hydro team completed a comprehensive Stormwater Utility Feasibility Study, which provided critical insights into Lambertville’s current stormwater management capacity and forecasted future needs.
Among the ongoing projects, Princeton Hydro is evaluating solutions for capturing runoff and reducing flooding in Lambertville's Music Mountain area, a critical greenspace in the heart of the city. This steep, wooded hillside, home to popular nature trails, serves as a cherished spot for after-school exploration, dog walking, and outdoor recreation. Music Mountain also plays a critical role in the city’s stormwater management system, acting as a natural buffer to protect lower-lying areas from flash flooding caused by runoff from the residential neighborhoods above. However, storm sewer outfalls discharging into the hillside have created deep erosion gullies, and during heavy rain events, the runoff has flooded the Fire Department. In collaboration with the City and the Fire Department, Princeton Hydro is designing a comprehensive solution that includes both the installation of a piped stormwater system and enlarging the inlet at the base of the mountain to better capture surface water runoff.
Additionally, on the Closson Farm property, Princeton Hydro is designing a riparian restoration project to manage the effects of increasing storm intensity. Funded by the National Fish and Wildlife Foundation, this project will result in 4.6 acres of restored floodplain, 300 trees planted, creation of wildlife habitat, measurable sediment and nutrient reduction, reduced stormwater runoff, community engagement, and new walking paths for recreation.
“Together with Lambertville, we are taking essential steps to enhance the city’s infrastructure and safeguard the community against future flooding. Our partnership reflects a shared commitment to protecting the environment and promoting resilience,” said Princeton Hydro’s Director of Restoration & Resilience, Christiana Pollack, CFM, GISP.
By embracing innovative stormwater solutions, Lambertville is not only enhancing its infrastructure but also setting a benchmark for resilience and environmental stewardship across New Jersey. This recognition reflects the city’s commitment to proactive flood management and sustainability, serving as an inspiration for other communities.
Princeton Hydro is honored to partner with the City of Lambertville on these important efforts. We extend our heartfelt congratulations on this well-deserved recognition and are excited to continue our collaboration on future projects that will further strengthen the city's resilience and protect its vibrant neighborhoods.

We are proud to announce that Princeton Hydro Aquatics Director Dr. Fred Lubnow and Founding Principal and Consultant Dr. Steve Souza have been appointed to the New Jersey HAB Expert Team as part of Governor Phil Murphy’s plan to enhance scientific expertise around water quality management and bolster the State's response to HABs.
The 10-person team, consisting of certified lake managers and cyanobacteria experts, will provide guidance to the New Jersey Department of Environmental Protection (NJDEP) on HAB prevention, treatment, and management for waterways throughout the state. The team is tasked with developing documents on best management practices; reviewing any proposed mitigation plans and technologies; reviewing water-quality data; and preparing a training workshop for NJDEP staff and stakeholders.
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. 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. By appointing a team that will work solely on HABs in the state, New Jersey is taking proactive steps to combat the spread.
Dr. Fred Lubnow is Princeton Hydro’s Director of Aquatic Resources. His vast expertise includes aquatic and watershed management, restoration ecology, and algae ecology. He is regionally recognized as a HABs expert as he has provided management recommendations and services for over 100 lakes and ponds in the Northeast, including Lake Hopatcong, New Jersey’s largest lake.
“I believe the knowledge and experience I have gained over the last 27 years as an environmental consultant will be useful in addressing questions and problems associated with HABs and lake management in general. I look forward to contributing any way I can in addressing issues associated with HABs and lake management in New Jersey.”
Dr. Steve Souza, whose 30-year career has been dedicated to the restoration of lakes and ponds, is a founding principal of Princeton Hydro and nationally recognized lake expert and consultant.
“Over the past decade the public has become increasingly aware of HABs and the health and ecological impacts caused by HABs. Unfortunately HABs and the problems caused by HABs are not going away; they are only expected to get worse due to climate change related effects on storm events, increases in air and water temperature, and an expansion of the algal growing season. It is thus important for us to learn more about what drives HABs as well as the most successful and sustainable means of avoiding, controlling and mitigating HABs. I am very excited to be part of the NJ Sea Grant HAB Expert Team. Through this very knowledgeable group of scientists, educators, and lake managers we hope to learn more about the causes of HABs and even more about what we can do to prevent or lessen their occurrence.”
All of us at Princeton Hydro are looking forward to seeing the work the expert team will undertake to improve the health, quality, and safety of New Jersey’s precious waterbodies. And, we extend a big congratulations to Fred, Steve and all other experts appointed to the team!

This message is from the NJDEP, Division of Dam Safety & Flood Engineering. Based on weather forecasts, it has been determined that the potential for a significant rainfall event exists in the area of your dam. At this time, we are reminding high/significant hazard dam owners to check your Emergency Action Plan to ensure that all contacts for emergency notification and emergency resources (engineers, contractors, supplies, etc.) are up to date. Please also take a moment to refresh yourself regarding the dam owner’s responsibilities in the event of an emergency. Please monitor your dam before, during, and after the storm event and report any concerns to this office. Prior to the storm, please take precautions to ensure that all spillways are clear of debris and that floating objects (boats, floating docks, etc.) which could block a spillway during high flow events are secured, where possible. If you discover that a potential emergency condition exists at the dam, you should immediately contact this office and our 24-Hour DEP Hotline at 1-877-WARNDEP (1-877-927-6337). You must also contact your engineer, as well as implement your emergency action plan. If your dam has any known vulnerabilities that you wish to discuss in advance of the storm, we recommend that you first contact your engineer. You may also contact our office at the number below. No modifications should be made to the dam without approval from this office. Please also be advised that the Division of Dam Safety and Flood Engineering does NOT recommend or require the lowering of impoundments prior to, during, or immediately following a storm event unless the integrity of the dam is in question. If a dam owner chooses to lower an impoundment for any reason, we encourage them to coordinate with local and county emergency management officials to ensure that any increased flow as a result of the lowering does not create flooding conditions downstream of the dam. The dam owner must also coordinate with the Division of Freshwater Fisheries (908-236-2118). A lake lowering permit (issued by Division of Freshwater Fisheries) is usually required prior to lowering.

The North American Lake Management Society (NALMS) awarded the Deal Lake Commission (DLC) with its “2018 Lake Management Success Stories” award. The award, which was presented at the NALMS 38th International Symposium, is given annually to recognize and honor an individual or group that has made significant lake/reservoir management accomplishments.
The DLC has overseen the management and restoration of Deal Lake and its watershed since 1974. Consisting of appointees from the seven municipalities abutting the lake, the DLC’s mission is to provide leadership, guidance and resources to preserve and restore Deal Lake and its tributaries as a healthy and stable ecosystem. A true challenge in an urban environment.
“It has been both a pleasure and an honor to work with the Deal Lake Commission for the past 35 years,” said Dr. Stephen Souza, Princeton Hydro Co-Founder. “They have shown great resolve to tackle some serious problems affecting the lake and its watershed, serving as a great example for other organizations involved in the restoration of urban lakes.”
Deal Lake is New Jersey’s largest coastal lake, encompassing 162 acres. The lake is surrounded by a 4,400-acre highly urbanized watershed, with the majority of development dating back to the 1960s-1980s. As a result, stormwater management, particularly with respect to water quality and volume management can be especially challenging. The DLC has embraced the numerous challenges, and has worked diligently over the years to correct these issues.
At the forefront, the DLC has been managing the primary cause of the lake’s eutrophication: stormwater runoff from the surrounding watershed. In 2014, with funding provided through the NJDEP’s 319(h) program, the DLC implemented a number of demonstration projects, specifically the construction of three bioretention basins, the installation of a large manufactured treatment device, the vegetative stabilization of over 500 feet of heavily eroded sections of the shoreline, and the construction of a rain garden at the Deal Lake boat launch.
Collectively these projects were shown to eliminate localized flooding, decrease floatable loading, and reduce nutrient, sediment and pathogen inputs to the lake. These and other projects implemented by the DLC over the years show that despite Deal Lake being located in a highly urbanized watershed, it is possible to implement cost-effective green infrastructure and stormwater retrofit solutions.
Deal Lake recently won another very competitive 319 (h) program for $735,000 for MTDs, tree boxes, and Green infrastructure improvements to Deal Lake, Sunset Lake and Wesley Lake.
The NALMS award nomination application, which was submitted by Dr. Souza, listed a number of additional achievements of the DLC, including:
