New Video Celebrates 50th Anniversary of Wild & Scenic Rivers Act

Communities across the nation are preparing to celebrate the 50th anniversary of the Wild and Scenic Rivers Act. This landmark legislation passed by Congress in October 1968 safeguards the free-flowing character of rivers by precluding them from being dammed, while allowing the public to enjoy them. It encourages river management and promotes public participation in protecting streams.

As part of the celebration, the National Park Service released a new video highlighting a handful of ‘Wild and Scenic’ designated rivers in the Northeast – the Farmington, Sudbury, Assabet, Concord, and Musconetcong Rivers – along with the organizations and community volunteers who work together to protect and care for these rivers.

Princeton Hydro is proud to work with two of the river stewards featured in the video: Musconetcong Watershed Association (MWA) and Farmington River Watershed Association (FRWA).

The Musconetcong River:

Designated ‘Wild and Scenic’ in 2006, the Musconetcong River is a 45.7-mile-long tributary of the Delaware River in northwestern New Jersey.

Princeton Hydro has been working with MWA in the areas of river restoration, dam removal, and engineering consulting since 2003 when the efforts to remove the Gruendyke Mill Dam in Hackettstown, NJ began. To date, Princeton Hydro has worked with MWA to remove five dams on the Musconetcong River, the most recent being the Hughesville Dam.

As noted in the video, the removal of these dams, especially the Hughesville dam, was a major milestone in restoring migratory fish passage along the Musconetcong. Only a year after the completion of the dam removal, American shad returned to the “Musky” for the first time in 250 years.

“The direction the river is moving bodes well for its recovery,” said Princeton Hydro President Geoff Goll, P.E., who was interviewed in the 50th anniversary video. “This multidisciplinary approach using ecology and engineering, paired with a dynamic stakeholder partnership, lead to a successful river restoration, where native fish populations returned within a year. ”

The Farmington River:

The Upper Farmington River, designated as ‘Wild and Scenic’ in 1994, stretches 14-miles through Connecticut starting above Riverton through the New Hardford/Canton town line. The river is important for outdoor recreation and provides critical habitat for countless wildlife.

Credit: FWRA.orgBack in 2012, Princeton Hydro worked with the FRWA and its project partners to remove the Spoonville Dam. Built in 1899 on the site of a natural 25-foot drop in the riverbed, the dam was originally a hydropower facility. The hurricanes and flood of 1955 breached the dam, opening a 45-foot gap and scattering massive dam fragments in the riverbed downstream. The remnant of the main dam persisted for decades as a 128-foot long, 25-foot high obstacle in the channel. The river poured through the breach in a steep chute that stopped American shad from proceeding further upstream to spawn.

The project was completed, from initial site investigation through engineering assessment and final design, in just six months. The dam removal helped to restore historic fish migrations in the Farmington River (including the American shad) and increase recreation opportunities.

Wild & Scenic Rivers Act:

Credit: NPS.govAs of December 2014 (the last designation), the National ‘Wild and Scenic’ System protects 12,734 miles of 208 rivers in 40 states and the Commonwealth of Puerto Rico; this is a little more than one-quarter of 1% of the nation’s rivers. By comparison, more than 75,000 large dams across the country have modified at least 600,000 miles, or about 17%, of American rivers.

In honor of the 50th anniversary of the Act and in an effort to designate many more miles of river as ‘Wild and Scenic,’ four federal agencies and four nonprofit groups are coordinating nationwide events and outreach. Managing agencies are the Bureau of Land ManagementFish and Wildlife ServiceForest Service, and National Park Service, along with American RiversAmerican WhitewaterRiver Network and River Management Society.

Lake Mohawk Country Club Publication Features Princeton Hydro

The Lake Mohawk Country Club (LMCC) recently published an article in The Papoose, the organization’s newsletter, that featured Princeton Hydro Founder Dr. Steve Souza and announced that he received the North American Lake Management Society’s “2017 Lake Management Success Stories Award” for his work with Lake Mohawk.

The award specifically recognizes the exceptional service provided to Lake Mohawk, the New Jersey Coalition of Lake Associations (NJCOLA) and the Lake Mohawk Preservation Foundation (LMPF). The nomination for the award was submitted by Barbara Wortmann, Interim GM of the LMCC, Ernest Hofer PE, Science Advisor to LMPF and Board President of NJCOLA, and the full Board of Trustees of NJCOLA.

As the article states, Steve and the Princeton Hydro team have worked to develop and implement successful lake management strategies to restore and protect the health of the lake and its surrounding watershed. Lake Mohawk is now a role model for all of New Jersey’s lakes.

While accepting his award Dr. Souza stated, “this would not have been possible had it not been for the foresight of the Lake Mohawk Country Club and the support we have received over the years from the Lake Board, the current General Manager Barbara Wortmann, Steve Waehler and the Lake Committee, Ernie Hofer and Gene DePerz of the Lake Mohawk Preservation Foundation, and of course the late Fran Smith.” Steve went on to thank his staff at Princeton Hydro, especially Chris Mikolajczyk, CLM and Dr. Fred Lubnow, for their efforts over the years.

More About Lake Mohawk Lake Restoration:

Nutrient pollution is one of the main problems affecting lakes throughout the United States. In small amounts, nitrates and phosphates can be beneficial to many ecosystems. However, in excessive amounts, nutrients cause eutrophication. Eutrophication stimulates an explosive growth of algae (algal blooms) that depletes the water of oxygen and cause serious water quality issues. Lake Mohawk was suffering from eutrophication issues.

In the early 1990’s, Princeton Hydro was contracted by the LMCC to conduct a detailed water quality and trophic state assessment of the lake. The data was used to prepare a comprehensive lake management master plan.

A unique element of the plan was the design and installation of a “one-of-a-kind” continual, dosing alum pumping system, which reduced and controlled the lake’s sizable internal total phosphorus load and the phosphorus originating from stormwater and other external sources. This innovative nutrient control program was the first of its kind in New Jersey, and, to this day, remains in operation and is the foundation of the lake’s restoration. Following suit from Lake Mohawk’s success, a similar system was also designed and installed in White Meadow Lake and that system is also largely responsible for its restoration.

The success of this program was recognized by the USEPA through an Environmental Excellence Award, by the NJDEP through an Environmental Initiative Award, by the NALMS through a Technical Merit Award, and now by NALMS with the 2017 Lake Management Success Stories Award.

Conservation Spotlight: FORTESCUE SALT MARSH AND AVALON TIDAL MARSH RESTORATION

HABITAT RESTORATION THROUGH APPLICATION OF DREDGED MATERIAL

New Jersey, like other coastal states, has been losing coastal wetland habitats to a combination of subsidence, erosion and sea level rise. The New Jersey Department of Environmental Protection received a grant from the National Fish and Wildlife Federation to address this issue and rejuvenate these critical habitats. Grantees were charged with providing increased resilience to natural infrastructure that will in turn increase the resiliency of coastal communities in the face of future storms like Hurricane Sandy.

As a consultant for GreenTrust Alliance, a land conservancy holding company, Princeton Hydro worked with several project partners, including NJDEP, the US Army Corps of Engineers, NJDOT, The Wetlands Institute, and The Nature Conservancy, to increase the marsh elevation to an optimal range where vegetation, and the wildlife that depends on it, can flourish. One of the techniques used for this project included the use of dredged material disposal placement, which involves using recycled sand and salt dredged from navigation channels to boost the elevation of the degraded marsh.

A media statement from NJDEP further explained the process, “sediments dredged from navigation channels and other areas are pumped onto eroding wetlands to raise their elevations enough to allow native marsh grasses to flourish or to create nesting habitats needed by some rare wildlife species. Healthy marshes with thick mats of native grasses can cushion the impact of storm surges, thereby reducing property damage.”

FORTESCUE SALT MARSH

The salt marsh at the Fortescue project site is part of the Fortescue Wildlife Management Area. The specific goal of the project was to restore and enhance the interior high and low marsh, coastal dune and beach habitats.

To achieve these habitat enhancements, the Princeton Hydro project team first established biological benchmarks of each targeted habitat type and evaluated them to determine the upper and lower elevational tolerances for target communities and plant species. Approximately 33,300 cubic yards of dredged materials were used to restore a degraded salt marsh, restore an eroded dune, and replenish Fortescue Beach. The eroded dune was replaced with a dune designed to meet target flood elevations and protect the marsh behind it against future damage. The dune was constructed using dredged sand, and, to prevent sediment from entering the waterways, a Filtrexx containment material was used.

AVALON TIDAL MARSH

This project site is a tidal marsh complex located within a back-bay estuary proximal to Stone Harbor and Avalon. Princeton Hydro and project partners aimed to enhance the marsh in order to achieve the primary goal of restoring the natural function of the tidal marsh complex.

Two main activities were conducted in order to apply the dredged material to the impaired marsh plain: 1.) the placement of a thin layer of material over targeted areas of existing salt marsh to increase marsh elevations, 2.) the concentrated placement of material to fill expanding pools by elevating the substrate to the same elevation as the adjacent marsh. In total, dredged material was distributed among eight distinct placement areas throughout the property’s 51.2 acres.

These coastal wetland restoration activities will help to prevent the subsidence-based marsh loss by filling isolated pockets of open water and increasing marsh platform elevation. In addition, the beneficial reuse of dredged material facilitates routine and post-storm dredging and improves the navigability of waterways throughout the U.S.

AQUATIC ORGANISM PASSAGE: A PRINCETON HYDRO BLOG SERIES

Fostering Ecological Balance in Food Webs

A major consequence of poorly designed culverts published in the NRCS' "Federal Stream Corridor Restoration Handbook"is the destabilization of food webs. Sufficient predators and prey must exist to maintain a balanced food web. For example, freshwater mussels (Unionidae) are a common snack among fish. A mussel’s life cycle involves using certain fish as a host for their larvae until these microscopic juveniles mature into their adult forms and drop off. During this period, the host fish will travel, effectively transporting a future food source with it.

In the presence of habitat fragmentation, the isolation of these symbiotic relationships can be devastating. Some mussel species rely on a small circle of fish species as their hosts, and conversely, some fish species rely on specific mussel species as their food. If a fish species is separated from its mussel partner, food shortages owing to a declining adult mussel population can occur.

Widespread Benefits to Flora, Fauna, and People

A shift in the 1980s recognized the importance of redesigning road-stream crossings for several reasons, including restoring aquatic organism passage and maintaining flood resiliency. Replacing culverts with larger structures that better facilitate the movement of both water and aquatic organisms benefit all species. Roads constructed over streams allow people to travel across natural landscapes while culverts that are fish-friendly convey water at a rate similar to the surrounding landscape, reducing scour in stream beds.

Fish, as well as semi-terrestrial organisms like crabs and salamanders, can take advantage of more natural stream environments and complete their migrations. Anglers appreciate healthy, plentiful fish populations nearly as much as the fish themselves. Recreation and economic growth also improve when streams regain the aquatic biological communities once lost through habitat fragmentation. According to USFWS, for every dollar spent on restoration through the Partners for Fish and Wildlife Program and Coastal Program Restoration Project, states gain $1.90 of economic activity. Stream restoration improves fish and wildlife habitat, which directly supports and enhances recreation opportunities for outdoor enthusiasts thus resulting in increased tourism-related spending and job growth.

Musconetcong Watershed Association Presents Princeton Hydro President with Prestigious “Friend of the River” Award

 

Musconetcong Watershed Association (MWA) held a dinner to celebrate its 25th anniversary as well as the 150th anniversary of the Asbury Grist Mill, which the MWA is working to restore. The evening included a cocktail hour, a buffet dinner, silent auction, remarks by the MWA President Tish Lascelle and Executive Director Alan Hunt, and a presentation of awards.

The MWA presented Princeton Hydro PresiPhoto by Tish Lascelle, President, Musconetcong Watershed Associationdent Geoff Goll, PE with the “Friend of the River” Award. This award, which has only been given seven times in MWA’s 25 years of service, recognizes individuals who have made a significant and sustainable difference in the Watershed and helped to advance its mission. Recipients of the Award have also demonstrated outstanding leadership through their volunteer efforts or partnerships with MWA.

Geoff was honored to receive the award alongside Paul Kenney of the National Park Service and Richard C. Cotton, a Managing Partner of the Hawk Pointe Golf Club and Asbury Farms Real Estate. Paul was assigned the Musconetcong River in late 2003 and was instrumental in obtaining the Musconetcong River’s Wild and Scenic Designation in 2006. He has continued to be an excellent resource of the National Park Service.  Richard is a founding member of the MWA’s Board of Trustee’s and continues to serve on the Board. He has dedicated his professional life to striking a balance between economic growth with environmental protection.

Geoff has been working with MWA in the areas of river restoration, dam removal, and engineering consulting since 2003, when the efforts to remove the Gruendyke Mill Dam in Hackettstown, NJ began. He has since worked with the Princeton Hydro team to remove five dams on the Musconetcong River, the most recent being the Hughesville Dam

MWA is an independent, non-profit organization dedicated to protecting and improving the quality of the Musconetcong River and its Watershed, including its natural and cultural resources. Members of the organization are part of a network of individuals, families and companies that care about the Musconetcong River and its watershed, and are dedicated to improving the watershed resources through public education and awareness programs, river water quality monitoring, promotion of sustainable land management practices and community involvement.

During the anniversary dinner, participants also got a sneak peek of a new video from the National Park Service that is set for public release in 2018. The video celebrates the upcoming 50th anniversary of the Federal Wild and Scenic Rivers Act, under which the Musconetcong River is protected, and explores the importance of free-flowing rivers and why Americans treasure them.

Aquatic Organism Passage: A Princeton Hydro Blog Series

Introducing part one of a multi-part blog series about aquatic organism passage
What you’ll learn:
  • What is aquatic organism passage?
  • Why is it important?
  • How does Princeton Hydro support it?

This photo from NYS DEC demonstrates a well-designed stream crossing.

Since the US government began allotting funds for building roads in U.S. national forests in the late 1920s, hundreds of thousands of culverts were built across the country. Culverts, or drainage structures that convey water underneath a barrier such as a road or railroad, were originally built with the intention of moving water quickly and efficiently. While this goal was met, many migratory fish and other aquatic organisms could not overcome the culverts’ high-velocity flows, sending them away from their migratory destinations. If the culvert was perched, or elevated above the water surface, it would require the migratory aquatic animals to both leap upwards and fight the unnaturally fast stream current to continue their journeys. Additionally, turbulence, low flows, and debris challenged the movement of aquatic organisms.

Thus, the goal of aquatic organism passage (AOP) is to maintain connectivity by allowing aquatic organisms to migrate upstream or downstream under roads. AOP “has a profound influence on the movement, distribution and abundance of populations of aquatic species in rivers and streams”. These aforementioned species include “fish, aquatic reptiles and amphibians, and the insects that live in the stream bed and are the food source for fish”.

This photo from NYS DEC demonstrates a poorly-designed stream crossing.

A poorly designed culvert can harm fish populations in multiple ways. If sturgeon aren’t able to surpass it, habitat fragmentation prevails. And so, a once-connected habitat for thousands of sturgeon breaks into isolated areas where a few hundred now live. When the population was in the thousands, a disease that wiped out 80% of the population would still leave a viable number of individuals left to survive and mate; a population of a few hundred will be severely hurt by such an event. In sum, habitat fragmentation raises the risk of local extinction (extirpation) as well as extinction in general.

The splintering of a large population into several smaller ones can also leave species more vulnerable to invasive species. Generally, the greater the biodiversity harbored in a population, the stronger its response will be against a disturbance. A dwindling community of a few hundred herring will likely succumb to an invasive who preys on it while a larger, more robust community of a few thousand herring has a greater chance of containing some individuals who can outcompete the invasive.

Aquatic Organism Passage in Action at Princeton Hydro

Princeton Hydro recently teamed up with Trout Unlimited to reconnect streams within a prized central-Pennsylvanian trout fishery.  Our team enabled aquatic organism passage by replacing two culverts in Pennsylvania’s Cross Fork Creek. Read about it here!
