Improving Water Quality & Reducing Habitat Loss with Floating Wetland Islands

Floating Wetland Islands (FWI), also known as floating treatment wetlands, are an effective alternative to large, watershed-based, natural wetlands. Often described as self-sustaining, FWIs provide numerous ecological benefits. They assimilate and remove excess nutrients that could fuel algae growth; provide habitat for fish and other aquatic organisms; help mitigate wave and wind erosion impacts; provide an aesthetic element; and can be part of a holistic lake/pond management strategy. FWIs are also highly adaptable and can be sized, configured and planted to fit the needs of nearly any lakepond or reservoir.

Princeton Hydro Senior Scientist Katie Walston recently completed the Floating Island International (FII) Floating Wetland Master Seminar. The seminar provided participants with an in-depth look at the various technologies and products FII offers. Through hands-on examples, course participants learned how to utilize wetland islands for fisheries enhancement, stormwater management, shoreline preservation, wastewater treatment and more.

“The Master Seminar was truly valuable both personally and professionally,” said Katie. “I learned a tremendous amount and thoroughly enjoyed the experience. It’s very fulfilling knowing that I can take the knowledge I’ve learned back to Princeton Hydro and make positive impacts for our clients.”

FII was launched by inventor and outdoorsman Bruce Kania who was driven by the desire to reverse the decline of wetland habitats by developing a new and natural stewardship tool that could clean water and, in the process, improve life for all living creatures. He found that the answer lies in Biomimicry: duplicating nature’s processes in a sustainable, efficient and powerful way to achieve impeccable environmental stewardship for the benefit of all life.

Bruce brought together a team of engineers and plant specialists and created BioHaven® floating islands. These islands biomimic natural floating islands to create a “concentrated” wetland effect. Independent laboratory tests show removal rates far in excess of previously published data: 20 times more nitrate, 10 times more phosphate and 11 times more ammonia, using unplanted islands. They are also extremely effective at reducing total suspended solids and dissolved organic carbon in waterways.

Due to population growth, industrialization and climate change, wetlands are at risk of rapidly declining in quantity and quality due. However, every floating wetland island launched by FII provides an effective strategy for mitigating and adapting to the impacts of over development and climate change.

The unique design of BioHaven® floating islands means that 250 square feet of island translates to an acre’s worth of wetland surface area. These versatile floating islands can be launched in either shallow or deep water, and can be securely anchored or tethered to ensure that they remain in a specific location. They are almost infinitely customizable, and can be configured in a variety of ways.

In addition to ongoing prototype development, FII offers licensing opportunities to businesses and production facilities worldwide. FII continues to research and develop collaborative pilot projects to quantify BioHaven® floating islands’ efficacy.

Many thanks to Bruce and Anne Kania for hosting the Floating Wetland Master Seminar and inspiring action through their knowledge, passion and ongoing endeavors.

 

Princeton Hydro Founder Invited to Speak at EPA’s Harmful Algal Blooms Workshop

Princeton Hydro Founder Dr. Steve Souza was an invited speaker at the USEPA Region 2 Freshwater Harmful Algal Blooms (HABs) and Public Drinking Water Systems workshop last week in Manhattan. The objective of the workshop was to share information about the monitoring and assessment of freshwater HABs and the efforts to minimize their effect on public drinking water and the recreational uses of lakes.

Steve’s presentation focused on the proactive management of HABs, providing useful tips for and real-world examples of how to address HABs before they manifest, and, if a HAB does manifest, how to prevent it from further exacerbating water quality and cyanotoxin problems.

The workshop was well attended with 80 people on site and 40 others participating via webinar link. Steve was joined by nine other invited speakers, most of whom were representing the USEPA, NYSDEC and NJDEP, who gave presentations on a variety of HABs related topics, including the optimization of water treatment operations to minimize cyanotoxin risks surveillance and assessment of HABs, and communicating HABs risks in recreational lakes and drinking water reservoirs.

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.

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!
