NJ Audubon undertakes $470G study of climate change impact on wetlands

Princeton Hydro is proud to be a partner on this incredible project

If you’ve ever gone birdwatching at any east coast wildlife refuge, then you probably understand the value of coastal impoundments. These man-made wetland habitats are contained by embankments and have gates that allow managers to manipulate water levels. In addition to being valuable, these structures are also very vulnerable to sea level rise and extreme weather.

Through a $470,000 federal grant, the New Jersey Audubon is implementing an initiative to study the vulnerability of these impoundments to climate change induced environmental impacts. Funded by the U.S. Department of the Interior via the National Fish and Wildlife Foundation, the Coastal Impoundment Vulnerability and Resilience Project (CIVRP) aims to map and catalog all state, federal, and privately owned coastal impoundments from Virginia to Maine. The project is a cooperative effort of a diverse team of partners including researchers from New Jersey Audubon, National Wildlife Federation, Conservation Management Institute (Virginia Tech), U.S. Fish and Wildlife Service and Princeton Hydro.

The CIVRP will ultimately reduce climate vulnerability and enhance the natural ecosystem function of these precious and treasured wetland habitats. Read the full article from MyCentralJersey.

Princeton Hydro Projects Recap

In Case You Missed It:
A Recap of Projects Recently Completed by the
Princeton Hydro Aquatic & Engineering Departments

Members of our New England Regional Office team conducted a detailed survey at a culvert prioritized for replacement in the Town of Stony Point, New York. This structure was one of several identified as important to both habitat and flood risk during the development of Stony Point’s Road-Stream Crossing Management Plan. The Princeton Hydro team will use the collected data to develop a conceptual design and implementation strategy for a replacement structure using the Stream Simulation design method developed by the U.S. Forest Service.

Special thanks to Paul Woodworth, Fluvial Geomorphologist, and Sophie Breitbart, Staff Scientist, for their excellent work on this project!

The Truxor was put to work dredging a pond in Union Gap, New Jersey. The Truxor is an extremely versatile amphibious machine that can perform a variety of functions, including weed cutting and harvesting, mat algae and debris removal, silt pumping, channel excavation, oil spill clean-up, and much more!

We recently designed and installed a solar-powered aeration system in Hillsborough, New Jersey. Solar pond and lake aeration systems are cost-effective, eco-friendly, sustainable, and they eliminate the need to run direct-wired electrical lines to remote locations. Princeton Hydro designs, installs and maintains various aeration and sub-surface destratification systems for public drinking water purveyors, municipal and county parks, private and public golf courses, and large lake communities throughout the East Coast.

Here’s a look at a project in Elizabeth, New Jersey to clear the area of phragmites. Phragmites is an invasive weed that forms dense thickets of vegetation unsuitable for native fauna. It also outcompetes native vegetation and lowers local plant diversity. Previously, the entire site was filled with phragmites. Late last year, we utilized the Marsh Master to remove the invasive weed. Now that its almost Spring, we’re back at the site using the Marsh Master to mill and cultivate the ground in preparation for re-planting native plant species. A big shout out to our Aquatic Specialist John Eberly for his great work on this project!

In this photo, our intern and engineering student currently studying at Stevens Institute of Technology, Veronica Moditz, is gathering data on the Hughesville Dam removal. She’s using GPS to check the elevation of the constructed riffle on the beautiful Musconetcong River.

Members of the Princeton Hydro team worked in South New Jersey doing annual maintenance on nine stormwater infiltration basins that were also designed and constructed by Princeton Hydro. The maintenance work involves clearing vegetation from the basins to ensure the organic matter does not impede infiltration of the water as per the basins’ design. This project also involves the management of invasive plant species within the basins. Stormwater infiltration basins provide numerous benefits including preventing flooding and downstream erosion, improving water quality in adjacent waterbodies, reducing the volume of stormwater runoff, and increasing ground water recharge.

We recently completed a project in New Jersey for which we used our Truxor machine to dredge a stormwater retention basin. The basin had accumulated large amounts of sediment which were impeding the flow of water into the basin. We equipped the Truxor with its standard bucket attachment and a hydraulic dredge pump. The dredging operation was a success and now the basin is clear and functioning properly.

6 Tips to Prepare Your Pond for Spring

It’s officially time to say good-bye 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 Your Pond

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, contact Princeton Hydro immediately. One of our engineers 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, contact us 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. Princeton Hydro professionals can conduct a “Spring start up” water quality analysis of your pond. The resulting data will enable us to develop pro-active, eco-friendly approaches to control nuisance aquatic species and promote environmental conditions supportive of a healthy and productive fishery.

4. Recognize and Reduce Erosion by Aquascaping the Shoreline

It’s important to check the pond’s shoreline for any signs of erosion, which can be easily stabilized by planting native, riparian plants. This is called “aquascaping”. Aquascaping is a great way to beautify the shoreline, stabilize erosion problems, create fish and amphibian habitat, attract pollinating species and song birds, and decrease mosquito breeding.

Our pond and wetland scientists can design and construct a beautiful, highly functional aquascaped shoreline for your pond.

5. Consider Installing an Aeration System

Sub-surface aeration systems eliminate stagnant water and keep your pond thoroughly mixed and properly circulated. Sub-surface aeration 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. Contact us to discuss if aeration is the right solution for you. If it is, we can design and install the appropriate system for your pond.

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 developed by a Princeton Hydro professional is the “blueprint” you need to proactively care for your pond in a very environmentally responsible manner.

Our Certified Lake and Pond Managers will 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. The plan will identify the causes of your pond’s problems and provide 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.

⋅ ⋅ ⋅

These are just a few tips to get your pond ready for a new season of enjoyment. Princeton Hydro can help you every step of the way. Our success in caring for ponds, lakes and reservoirs is the result of starting with the right plan and applying customized, environmentally-sound management techniques. Please contact us to discuss your pond management needs and to schedule an assessment.

The Plight of Aging Dams, and One Solution

As dams age, the danger to life and property around them increases. If they were to suddenly fail and flood downstream communities and infrastructure, there would be serious loss of property and life. More and more, dam removal has become the best option for property owners who no longer want or can no longer afford the rising cost of maintenance and repair work required to maintain such a complex structure.

The Courier-Post recently published this Commentary piece titled, “The Plight of Aging Dams, and One Solution”, which was written by Princeton Hydro’s Vice President and Principal Engineer Geoffrey M. Goll:

Many of our nation’s dams, while originally intended to provide benefits for mills, water supply and energy generation, are severely aged and unmaintained. Nearly 20,000 of the dams on the Army Corps of Engineers’ National Inventory of Dams – which doesn’t even include many dams that are not inventoried or known about – were built in the 1960s. With expected lifespans of 50 years, these dams have reached their limit. And by 2020, 70 percent of all dams will be over 50 years old. Like roads and bridges, dams also require upkeep, maintenance and eventually removal or rehabilitation.

As dams age, the danger to life and property around them increases. If they were to suddenly fail and flood downstream communities and infrastructure, there would be loss of property and life. The Association of State Dam Safety Officials, the professional organization for dam safety engineering professionals and regulators, estimates there would need to be a $21 billion investment to repair just 2,000 deficient, high-hazard dams. More and more, the removal of dams has become an option for owners who no longer want or no longer can afford the rising cost of maintenance and repair work required to maintain such a complex structure.

For dams like this, removal benefits local economies, and eliminates threats to people and property in local communities. There are also many byproduct benefits, including restoring fish migration routes, improving water quality, restoring floodplain functions and values, and increasing biodiversity.

On Sept. 8, we had the honor of meeting the Secretary of the Interior Sally Jewell during a visit of our Hughesville Dam removal project on the Musconetcong River, located in northwestern New Jersey. This project exemplifies the successes that can be achieved through public-private partnerships, including local communities, state and federal agencies, nongovernmental organizations, and private commercial entities. This is the fifth dam removed on the Musconetcong River by a coalition of stakeholders, led by the Musconetcong Watershed Association. The Department of the Interior (specifically, the U.S. Fish and Wildlife Service) provided funding to remove this very old, out-of-compliance dam.

The success of these partnerships is due to the unique strengths that each organization brings to the table. This project achieved the removal of a flood and safety hazard, and will restore additional river miles for migratory fish, improve water quality by removing the heat sink of the reservoir, and provide additional safe passage for recreation along the river.

It is easy to see why Secretary Jewell chose this site to visit, but the old and outdated dam at Hughesville is far from alone. Across the nation, we need to remove dams like this at a much larger scale – aging dams that no longer are of value to us, but increase the danger to those who live downstream. If we can build on this momentum and start to address the issue of dam safety compliance on a national scale, we can address these threats to American’s safety and strengthen local economies.

Lake Management and Restoration in the Hudson River Valley

Lake Management Planning in Action
at Sleepy Hollow Lake and Truesdale Lake

The Hudson River Valley encompasses 7,228 square miles along the eastern edge of New York State. It comprises 3 million residents, 133 communities and 553 significant freshwater lakes, ponds and reservoirs. Princeton Hydro has worked with municipalities and organizations in the Hudson River Valley for over 18 years actively restoring, protecting and managing waterbodies throughout the area.

Princeton Hydro is currently implementing customized Lake Management Plans at two waterbodies in the Hudson River Valley: Sleepy Hollow Lake, a 324-acre drinking water reservoir/recreational lake located in Green County, NY and Truesdale Lake, an 83-acre lake in Northern Westchester County, NY.

Sleepy Hollow Lake

Stretching over two and a half miles long and reaching depths of approximately 70 feet, Sleepy Hollow Lake is a NYSDEC Class “A” drinking water reservoir that provides potable water for the Sleepy Hollow community. The lake is also extensively used by residents for swimming, boating and water-skiing. And, it is recognized as an outstanding large-mouth bass and white crappie (current New York State record holder) fishery!

Princeton Hydro was hired by the Association of Property Owners (APO) at Sleepy Hollow Lake to develop a comprehensive lake management plan. The first step involved an in-depth analysis of the biological, chemical and physical attributes of the lake, with the goal being to generate a database that can be used to better understand the interactions defining the Sleepy Hollow Lake ecosystem.

The data collection and investigation phase includes:

  • Watershed Investigation: an in-depth assessment of the major and minor tributaries and road network in order to identify areas of stream bank and ditch erosion; sources of both sediment and nutrient loading to the lake
  • Bathymetric Survey: the accurate mapping of water depths and the quantification of the amount of accumulated, unconsolidated sediment present in the lake
  • Fisheries & Food Web Study: the collection of fish and plankton data for the purpose of creating a comprehensive fisheries management program focused on managing the lake’s outstanding fishery, further promoting the ecological balance of the lake, and enhancing lake water quality
  • Aquatic Plant Mapping: the development of detailed maps identifying the plant species present in the lake along with their relative abundance and distribution throughout the lake, but especially within the shallower coves
  • Hydrologic & Pollutant Budget: the computation of the lake’s hydrologic budget and pollutant loading budget. The hydrologic budget represents the water balance of the lake and is an estimate of all of the inputs and losses of water. The pollutant budget represents an estimate of the amount of nitrogen and phosphorus entering the lake from various sources. These data are used to evaluate the effectiveness of lake management options, enabling us to determine the best, most ecologically sound and most cost-effective approach to protect and improve the lake’s water quality now and into the future.

Princeton Hydro is now in the process of utilizing all of the data developed during the investigation phase of the project to create a comprehensive Lake Management Plan that will be used to guide the APO’s future lake restoration and protection initiatives. The Lake Management Plan and supporting data will also be used by Princeton Hydro on behalf of the APO to seek grant funding for various lake and watershed restoration projects.

Princeton Hydro is also overseeing the aquatic plant management program at Sleepy Hollow Lake, the focus of which is to control invasive plant species in a manner consistent with and complimentary of the lake’s overall ecological enhancement.

Truesdale Lake

At Truesdale Lake, Princeton Hydro is working with the Truesdale Lake Property Owners Association (TLPOA) to develop a comprehensive Lake Management Plan. The Plan provides a detailed project implementation roadmap for TLPOA, including recommendations for priority ranking of particular activities and restoration measures. A key element of the Plan are the short-term (1-year) and long-term (5-year) water quality and problematic algae and invasive aquatic plant control goals. Another highlight of the Plan is the review of Federal, State, County and local grants, programs and initiatives that may provide funding for identified lake and watershed projects.

During the Plan’s development, Princeton Hydro has provided the TLPOA with lake management consultation services such as community education initiatives, the coordination of NYSDEC permitting activities associated with the implementation of lake restoration measures, and the oversight and administration of an aquatic weed management program at the lake.

Earlier this year, Truesdale Lake experienced excessive aquatic weed growth, which significantly reduced the water quality, recreational use and aesthetics of the lake. Princeton Hydro utilized its Truxor, an eco-friendly, amphibious machine, to cut and remove the nuisance weed growth from the lake. This program helped reduce the negative impacts to the lake and lake users caused by the dense weed growth. Future use of the Truxor to remove invasive weeds is already part of the long-term Lake Management Plan for TLPOA. The Truxor will be used in concert with other measures to control invasive weed growth and restore a more balanced native aquatic plant community.

Success Spotlight: Strawbridge Lake

The Princeton Hydro team recently completed a spadderdock removal project at Strawbridge Lake, a 33-acre lake considered to be one of the most valuable open space assets in Moorestown, New Jersey.

Spadderdock is an invasive aquatic plant found in lakes and ponds throughout the Eastern US. It can grow quickly and reach large populations totally covering the water surface and shading the bottom so that nothing else can grow. Spadderdock can eliminate important, native plant species and clog waterways.

Princeton Hydro utilized its Truxor DM 5045, an eco-friendly amphibious machine, to dig up the plants at their roots and remove them from the lake. Check out the below before and after photos to see the dramatic transformation. Special kudos to our Senior Scientist J.P. Bell for a job well done!

Four Ways Climate Change Could 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. 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.

2015-07-07-10-01-20Lakes 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. Most of the time the results are negative and the impacts severe. 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.

Princeton Hydro has 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 fishes, 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 fishes 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.

Enjoy Your Labor Day Adventures Responsibly

Princeton Hydro Offers
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, scientists 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.

Deal Lake Improves Water Quality on a Sustainable Basis

Success Spotlight: Deal Lake Watershed Protection Plan Implementation Project

Deal Lake Commission, Interlaken, New Jersey

Deal Lake is the largest of New Jersey’s coastal lakes, encompassing 155 acres and spanning over 27 miles of shoreline. The lake’s 4,400-acre watershed is highly developed, with the majority of development dating back to the 1940s-1960s. As a result, stormwater management, particularly with respect to water quality and volume management, is largely lacking.

Since 1980, the Deal Lake Commission (DLC) has served as the State-appointed steward of the lake.  Princeton Hydro secured the DLC $450,000 in 319(h) funding to implement the lake’s New Jersey Department of Environmental Protection-approved Watershed Protection Plan. The 319(h) funding was used by the DLC to conduct three projects designed to decrease stormwater-based pollutant loading, improve the lake’s water quality, and restore heavily eroded sections of the shoreline.

Asbury Park Comstock Street MTD

Screen Shot 2016-05-23 at 9.20.04 AMThis project involved the installation of a manufactured treatment device (MTD). MTDs are very effective “retrofit” solutions that can be used to address stormwater issues even in highly developed areas. The MTD installation was complicated by site constraints including sub-surface infrastructure. Post-installation field testing and STEPL modeling conducted by Princeton Hydro confirmed that the MTD significantly decreased the pollutant loading from one of the lake’s major stormwater outfalls.

 

Colonial Terrace Golf Course Bioretention BMPs
Screen Shot 2016-05-23 at 9.25.17 AM

Princeton Hydro conducted the field testing, engineering design, and permitting of three bio-infiltration basins constructed at the Colonial Terrace Golf Course (CTGC). Post-project-completion field testing showed each basin is capable of fully infiltrating the runoff generated by storms as great as 1.5 inches per hour. In addition, over 300 feet of eroded shoreline was stabilized with native plants. Doing so helped create a dense buffer that inhibits passage of Canada geese from the lake onto the golf course.

 

Asbury Park Boat Launch Shoreline Stabilization

Princeton Hydro developed a bio-engineering design for the stabilization of a badly eroded 250-foot segment section of shoreline adjacent to the Asbury Park boat launch. Coir fiber logs were used in conjunction with native plant material. As with the CTGC planting, help was provided by local volunteers and the DLC commissioners. The final element of the project involved the construction of a bioretention rain garden to control the runoff from the boat launch parking area. Signage was also installed to inform the public about the project and the benefits of shoreline naturalization.

 

The Deal Lake Watershed Protection Plan Implementation Project proved that despite Deal Lake being located in a highly urbanized watershed, it is possible to implement cost-effective green infrastructure and stormwater retrofit solutions capable of significantly decreasing pollutant loading to the lake.  These measures are part of the DLC’s continued efforts to utilize environmentally sustainable techniques to improve the lake’s water quality. This project won a North American Lake Management Society Technical Merit Award.
