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

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

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

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

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

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

Providing Funding:

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

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

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

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

Increasing Expertise & Implementing Prevention Tactics:

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

Connecting with Communities:

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

Flipping the Script on American Environmental Thought: FREE Presentation Download

 

The Watershed Institute held its 3rd Annual New Jersey Watershed Conference, an educational event that aims to advance knowledge and communications on issues related to water quality and quantity across the state. The event included a variety of presentations from local experts on watershed management, stormwater, and problems and solutions related to the health of New Jersey’s watersheds.

During the conference, Princeton Hydro’s Marketing Coordinator Kelsey Mattison, a St. Lawrence University graduate with a degree in English and environmental studies, lead a workshop that explored binaries in environmental thought and how to break through those limiting thought processes in order to advance a more productive and shared understanding of our natural world.

The presentation, titled “Flipping the Script on American Environmental Thought,” discussed how black-and-white thought processes (a.k.a. binaries) cause us to view issues as one or the other, leaving little to no room for the possibility of blending the two.

Historically, American thought has viewed environmental issues through a binary lens: either we favor human society, or we favor the environment, and this juxtaposition has rarely allowed for integration between the two perspectives.

Take, for example, the two concepts of preservation and conservation toted by John Muir and Gifford Pinchot, respectively. Muir’s concept of preservation argued that humans should set land aside to leave untouched to preserve its natural beauty, while Pinchot’s concept of conservation advocated for a responsible use of the land’s resources. Both are forms of environmental advocacy, but neither leave much room to combine the two ideas, ultimately creating a black and white binary surrounding human responsibility to the planet. This makes it difficult to then make any compromise on issues related to managing or utilizing our natural resources.

The workshop also explored answers to the important question of: “How do we flip the script to be more inclusive?” Participants discussed ideas around utilizing Values-Based Communication in order to connect with people from different groups/with different values. A few of the communication strategies Kelsey presented, include:

  • Finding Common Ground:

    When groups are telling such different narratives, it can be hard to see that their goals might actually be completely in line. By first identifying what each group’s priorities are, we can better understand their needs in order to help fulfill them. This allows people with seemingly conflicting beliefs to work towards a common goal.

  • Seeing More than Two Sides:

    Generally, people default to thinking there are only two sides to an issue, but no conflict is ever truly just one thing or the other. Even if there are overtly two options, the issue is always more complex. When resolving conflict, it’s almost always possible to find at least one thing the two sides have in common.

Overall, Kelsey’s workshop emphasized the importance of open-mindedness and inclusion in our approach to environmental action in order to bring people together and foster real change. If you’re interested in learning more, click here for a free download of Kelsey’s full presentation.

The New Jersey Watershed Conference, of which Princeton Hydro was a sponsor and exhibitor, also included presentations on topics ranging from urban flooding to microplastics in our waterways to green infrastructure. Dr. Fred Lubnow, Princeton Hydro’s Director of Aquatic Programs, presented on the “Causes and Impacts of Harmful Algal Blooms.” To view the complete agenda, go here.

Laura Wildman Awarded for “Bringing the Presumpscot River Back to Life”

Photo provided by the Friends of the Presumpscot River

The Friends of the Presumpscot River (The Friends) Board of Trustees awarded Laura Wildman, P.E., Princeton Hydro’s New England Regional Office Director and Water Resources and Fisheries Engineer, with its “Chief Polin Award.” The award recognizes Laura for her accomplishments and efforts in bringing life back to the Presumpscot River and rivers across the nation. The award was presented at The Friends’ Three Sisters Harvest Dinner & Annual Celebration.

The Chief Polin Award recognizes those who are making significant efforts to restore fish passage, improve water quality and bring back the natural character of the Presumpscot river.During her acceptance speech, Laura thanked The Friends for its continued dedication to restoring fish passage and revitalizing the river. “I am so proud to be part of the ‘river warriors’ team,” Laura said. “Our collective efforts to protect and restore the river have resulted in invaluable benefits to fish, aquatic organisms, wildlife, and the surrounding communities.”

The award is named after local Abanaki tribe leader Chief Polin, who led the first documented dam protest in New England during the mid-1700s, advocating for fish passage, which had been compromised by the first dams built along the river. The award recognizes those who are making significant efforts to restore fish passage, improve water quality, and bring back the natural character of the Presumpscot River. Sean Mahoney from the Conservation Law Foundation also received the Chief Polin Award during the Annual Celebration.

Map provided by The Friends of the Presumpscot RiverLocated in Cumberland County, Maine, the Presumpscot is a 25.8-mile-long river and the largest freshwater input into Casco Bay. The river has long been recognized for its vast quantity of fish. According to The Friends, when Europeans first arrived, they reported that “the entire surface of the river, for a foot deep, was all fish.”

In the 1730s, however, the construction of dams halted the passage of fish up the river. As more dams sprung up in the following centuries, the ecological vitality of the river steadily declined.

For more than 250 years, people have advocated for the unobstructed passage of fish up the Presumpscot River. Over the last 50 years, the river has undergone profound transformation due to the enactment of the Clean Water Act, the removal of a few dams, and the installation of fish passages on existing dams. Fish passage at Cumberland Mills Dam, which was completed in 2013, restored critical habitat to sea run fish such as shad, American eel, and river herring, and allowed them to move upstream again.

Saccarappa Falls dam removal in actionIn July, work began to restore a large reach of the river through Westbrook, Maine. The project involves the removal of two dam spillways from the upper Saccarappa Falls and the construction of a fishway around the lower falls. The project, which was three years in the making, was finally approved to move forward once the City of Westbrook, Sappi Fine Paper, the U.S. Fish and Wildlife Service, the Maine Department of Marine Resources, and the nonprofits, Friends of the Presumpscot River and Conservation Law Foundation, were able to reach a ground breaking settlement. The Saccarappa Falls project is a major step in restoring the river and was a focal point of the Three Sisters Harvest Dinner, celebrating decades of effort on the parts of the Friends of the Presumpscot along with their numerous project partners, including Princeton Hydro.

About the Friends of the Presumpscot River: A nonprofit organization founded in 1992, supported primarily by membership dues and small donations. Its mission is to protect and improve the water quality, indigenous fisheries, recreational opportunities and natural character of the Presumpscot River.

DIY: Protecting Water Quality in Your Community

There are lots of things we can do to preserve our precious water resources. Reducing stormwater pollution in our neighborhoods is something everyone can take part in. Storm drain cleaning is a great place to start!

DIY Storm Drain Cleaning

Urbanization has fundamentally altered the way that water moves through the landscape. Stormwater that doesn’t soak into the ground runs along streets and parking lots and picks up pollutants. Much of the pollution in our nation’s waterways comes from everyday materials like fertilizers, pesticides, motor oil, and household chemicals. Rainwater washes these substances from streets, yards and driveways into storm drains.

It’s a common misconception that storm drains lead to wastewater treatment plants. In actuality, storm drains rarely lead to treatment plants and instead stormwater systems carry untreated water directly to the nearest waterway. This polluted runoff can have negative impacts on water quality, overstimulate algal growth (both toxic and non-toxic), harm aquatic species and wildlife, and cause trash and debris to enter our lakes, streams, rivers and oceans.

https://www.middlesexcentre.on.ca/Public/Stormwater

We can all do our part to improve and preserve water resources in our community and beyond!

Keeping neighborhood storm drains cleaned is one simple step. Removing debris that collects in nearby stormwater catch basins, storm drains and along curbs promotes cleaner runoff, reduces the potential for flooding, and decreases the amount of pollution and trash entering our waterways.

Follow these simple steps for DIY storm drain cleaning:

  1. Photo: Santiago Mejia, The ChronicleRake/sweep and discard debris that has collected on top of the storm grate and in curbside rain gutters. Please note: If you notice a major blockage or issue with a storm drain, contact your local municipality immediately.
  2. Use a scrub brush or toilet bowl scrubber to remove debris that may be stuck to the storm grate.
  3. Adopt a storm drain(s) and maintain a regular cleaning schedule: Make a note on your calendar each quarter to clean and clear debris from storm drains nearby your home or workplace. And, make a habit of checking your storm drains after rainstorms when clogging is most common.
  4. Host a community clean-up day that includes trash pick-up, storm drain cleaning, and disseminating information on the impacts of stormwater runoff and what we can do to help.
  5. Consider contacting your local watershed association or municipality about getting drain markers installed on storm drains throughout the community. The markers act as a continued public reminder that anything dumped into a storm drain eventually ends up in our precious waterways downstream.

Remember: Small actions lead to big achievements in protecting water quality. 

Enjoy Your Labor Day Nature Adventures Responsibly

Seven Tips for Environmentally-Friendly Outdoor Fun

Labor Day is right around the corner! Many people will soon be packing up the car with fishing gear and heading to their favorite lake for a fun-filled weekend.

As biologists, ecologists, environmentalists, and outdoor enthusiasts, all of us at Princeton Hydro fully enjoy getting outside and having fun in nature. We also take our responsibility to care for and respect our natural surroundings very seriously. We play hard and work hard to protect our natural resources for generations to come.

These seven tips will help you enjoy your Labor Day fishing, boating, and outdoor adventures with minimal environmental impact:

  • Before you go, know your local fishing regulations. These laws protect fish and other aquatic species to ensure that the joys of fishing can be shared by everyone well into the future.

  • Reduce the spread of invasive species by thoroughly washing your gear and watercraft before and after your trip. Invasives come in many forms – plants, fungi, and animals – and even those of microscopic size can cause major damage.

  • Stay on designated paths to avoid disrupting sensitive and protected areas, like wetlands, shorelines, stream banks, and meadows. Disturbing and damaging these sensitive areas can jeopardize the health of the many important species living there.

  • Exercise catch and release best practices. Always keep the health of the fish at the forefront of your activities by using the right gear and employing proper techniques. Get that info by clicking here.

  • Use artificial lures or bait that is native to the area you’re fishing in. Live bait that is non-native can introduce invasive species to water sources and cause serious damage to the surrounding environment.

  • Plan ahead and map your trip. Contact the office of land management to learn about permit requirements, area closures and other restrictions. Use this interactive map to find great fishing spots in your area, the fish species you can expect to find at each spot, nearby gear shops, and more!

Armed with these seven tips, you can now enjoy your weekend while feeling rest assured that you’re doing your part to protect the outdoor spaces and wild places we all love to recreate in! Go here to learn about some of the work Princeton Hydro does to restore and protect our natural resources.

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.

Recycled Christmas Trees Used to Restore Disappearing NJ Shoreline

INNOVATIVE COASTAL RESILIENCY DESIGN USING RECYCLED CHRISTMAS TREES IMPLEMENTED BY VOLUNTEERS ALONG DISAPPEARING POINT PLEASANT SHORELINE

To prevent further erosion at the Slade Dale Sanctuary in Point Pleasant, dozens of volunteers helped stabilize the shoreline using a technique that has never been done before in New Jersey.  On Saturday, American Littoral Society, in partnership with Princeton Hydro, Borough of Point Pleasant, New Jersey Nature Conservancy, New Jersey Corporate Wetlands Restoration Partnership, and the Point Pleasant Rotary Club, organized dozens of volunteers to restore the shoreline and prevent further erosion at the Slade Dale Sanctuary using recycled Christmas trees.

As one of only a few areas of open space left in Point Pleasant, the 13-acre Slade Dale Sanctuary is an important part of the local ecosystem, and is home to a number of unique animals and plants. This waterfront preserve along the North Branch Beaver Dam Creek is predominantly tidal marsh, which provides habitat for various birds, including osprey, as well as passive recreation opportunities for the community.

Unfortunately, the Slade Dale Sanctuary is disappearing. Since 1930, the shoreline of Slade Dale Sanctuary has retreated approximately 300 feet, equal to the length of a football field, and the channels into the marsh have increased in number and size, according to a study we conducted on behalf of American Littoral Society, for which we provide engineering and natural resources management consulting services.

In order to stabilize the shoreline, 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 to enhance ecological value and reduce erosion. The final conceptual plan for restoration uses tree vane structures to attenuate wave action, foster sediment accretion, and reduce erosion along the coast.

To implement this vision and begin building back marsh, the project team is constructing several Christmas tree breakwaters and Christmas tree vanes that mimic naturally occurring debris structures in tidal systems and enhance habitat opportunity and shelter for aquatic life. Volunteers came together on Saturday, May 11 to help with the construction. The Mayor of Point Pleasant Robert A. Sabosik also attended the event, “The Barnegat Bay is an attribute that we all enjoy, and it’s something we have to protect.”

After the 2018 holiday season, the Good Sheppard Lutheran Church in Point Pleasant provided space to collect and store donated Christmas trees, which were then moved to the marsh a few days before the event. On the day of the event, recycled Christmas trees were transported from their staged locations on the marsh to the breakwater sections that were previously installed in the water. To transport them across the water to the pilings, volunteers used two methods: by walking a skiff boat loaded with trees through the water to the pilings or by forming assembly line from the shore to pilings to guide floating trees through the water (check out the album below!).  Then, they stuffed the Christmas trees between the pilings, securely tied them down, and staked Christmas trees directly into the creek bottom. For extra assurance, the placed and tied heavy bags of used oyster shells on top of the tree line. Oyster shells were donated by local Monmouth County restaurants in an effort to reduce waste streams.

“We really enjoyed participating in this event with American Littoral Society and so many wonderful volunteers,” Christiana L. Pollack, GISP, CFM, Princeton Hydro’s Project Manager for this restoration effort. “It is so wonderful to see this project coming to fruition. We’re so proud of our partnership with American Littoral Society and our combined efforts to revitalize and rehabilitate our precious coastal habitats.”

Members of the media were invited to attend the volunteer event. News 12 New Jersey covered the event and aired a story on it during their Sunday news broadcast, and NJTV News will be airing the story in the near future.

Many thanks to everyone who came out in support of this important restoration effort at Slade Dale Sanctuary American Littoral Society hosts volunteer events throughout the year. Go here to get involved.

 

Arbor Day Bird Walk & Planting at Exton Park

On Thursday, April 25th, 2019, we teamed with the Friends of Exton Park and Homenet Automotive to host an early Arbor Day celebration at Exton Park in Exton, Pennsylvania. Paired with Bring Our Daughters and Sons to Work Day, the event drew over 35 volunteers (of all sizes) to help clean up Exton Park and plant 18 trees!

The day started with a leisurely bird walk throughout the park lead by Friends of Exton Park birders. Participants spotted Red-winged Blackbirds, a Solitary Sandpiper, a Wilson’s Snipe, a Downy Woodpecker and even a Green Heron.

After the bird walk, planting and clearing began. Together, volunteers cleared a hefty amount of multiflora rose and garlic mustard, two invasive species prevalent in the park. With the help of our Landscape Designer, Cory Speroff, MLA, ASLA, CBLP, and Senior Limnologist, Mike Hartshorne, volunteers also planted eight river birch, five red osier dogwood, and five swamp white oak trees throughout the park.

At Princeton Hydro, we value working with our clients and partners to create sustainable landscapes that include native plants that will thrive in our local ecosystems. At all our project sites, we aim to restore and maintain our natural habitats and landscapes. And, we love using teamwork to do it!

We were proud contribute the trees for this event and thank our volunteers for all their hard work. This is the second year we have participated in this Arbor Day volunteer event. We are looking forward to making it an annual tradition!

Friends of Exton Park offers weekly bird walks and volunteer opportunities throughout the year. Go here to learn more and get involved.

American Shad Discovered Just Miles Upstream of Former Columbia Dam

Struggling fish species returns to spawning grounds for the first time in over a century, just months after dam removal completed

For the first time in over a century, American Shad (Alosa sapidissima) have been discovered upstream from the former Columbia Dam site on the 42-mile long Paulins Kill river, an important tributary to the Delaware River in northwestern New Jersey. Princeton Hydro’s Senior Water Resources Engineer and avid fisherman, Dr. Clay Emerson, PE, CFM, caught an American Shad in the Paulins Kill miles above the previous dam site this past weekend.

A successful collaboration between The Nature Conservancy, American Rivers, Princeton Hydro, U.S. Fish and Wildlife Service, and NJDEP Division of Fish and Wildlife Service, resulted in the removal of the out-of-commission hydroelectric Columbia Dam just months ago. Prior to this removal, American Shad and other migratory fish could not make it past the large dam structure to swim upstream to their important breeding grounds.

“I was thrilled to feel the familiar hit and see the flash of an American Shad as I reeled the fish to shore. Being an avid shad fisherman and enthusiast, I knew the significance of seeing this beautiful fish back in a place where it’s always belonged,” said Clay. “We are thrilled to witness the American Shad return upstream so quickly after the century-old Columbia dam was removed. It’s a testament to the nearly instant benefits that dam removal has on the riverine ecosystem.”

The American shad’s return is an excellent sign of the overall ecological health and diversity of the river. Historically, dams, overfishing, and pollution have caused population decline in many of the major eastern U.S. rivers. American Shad, deemed the “Mid-Atlantic salmon,” are anadromous, which means they spend much of their lives in the ocean but return to rivers and their tributaries to spawn. This long distance swimmer makes it one of the Earth’s great travelers. After spawning upstream in rivers of the East Coast, American Shad migrate to their primary habitat in the Atlantic Ocean up in the Gulf of Maine. Unlike the salmon of the Pacific Ocean, American Shad may return to their spawning grounds multiple times over their lifetime. The species is a key prey species for many large fish and cetaceans like dolphins and whales in the Atlantic Ocean.

“The best indicator of river water quality improving in the Paulins Kill is the appearance of shad miles upstream from the Columbia Dam,” said Dr. Barbara Brummer, New Jersey State Director of The Nature Conservancy. “Today, we celebrate proof that with the 100-year dam impediment removed, they are once again successfully swimming up the river. I could not be happier! This is what teamwork and passion for nature can achieve. It is a great day for conservation in New Jersey, with many more great days for shad in the Paulins Kill to come.”

Princeton Hydro was contracted to investigate, design, and apply for permits for the removal of this dam as requested by American Rivers in partnership with the New Jersey chapter of The Nature Conservancy. The firm investigated, designed, and prepared the necessary permits for the dam removal. The team of engineers and ecologists studied the feasibility of removal by collecting sediment samples, performing bioassay tests, and conducting a hydraulic analysis of upstream and downstream conditions.

“We are proud to be a part of this collaborative project, which has had an immediate and positive impact to the ecosystem of the Delaware River Watershed and its fishery resources,” said Princeton Hydro’s President Geoffrey Goll, PE. “Re-discovering this Delaware River diadromous icon upstream of the former dam is a very promising sign that the river will once again return to a major migration route and nursery for American Shad. This is why we do what we do!”

This Columbia Dam Removal project could not have been possible without the hard work and dedication of the following partner organizations: The Nature Conservancy of New Jersey, American Rivers, Princeton Hydro, U.S. Fish and Wildlife Service, RiverLogic Solutions, NJDEP Division of Fish and Wildlife Service, and SumCo EcoContracting.

Anglers are reminded, according to New Jersey fishing regulations, except for the Delaware River mainstem it is illegal to fish for shad in any fresh waters of New Jersey.

Princeton Hydro has designed, permitted, and overseen the reconstruction, repair, and removal of a dozens of small and large dams in the Northeast. To learn more about our fish passage and dam removal engineering services, visitbit.ly/DamBarrier.
