New Book Aims to Protect and Restore Fish Migrations

Rivers are a critical natural resource and an essential element for the health and survival of billions of people and countless species. Flourishing populations of migratory fish are an important indicator of a healthy, coastally connected river and a robust aquatic ecosystem as a whole. Migratory fish help to maintain a balanced food web, support productive river systems, and provide income for people around the world.

Yet many migratory fish species are severely threatened primarily due to man-made obstacles like dams and weirs, which disrupt the natural flow of rivers and prevent fish migration. When fish can’t reach their habitat, they can’t reproduce and maintain their populations.

“Ultimately our ambition is to contribute in a positive way to making a better world and a positive difference for migratory fish, nature and humans on local and global levels by inspiring new initiatives for and with people all around the world,” as stated on www.fromseatosource.com. “Whether the challenge is simply to increase access to spawning habitats through connectivity improvements for salmon, or to maintain the livelihoods for hundreds of millions of people dependent upon fish and fisheries in the great rivers of Asia, Africa and South America, we hoped our book would help to achieve these goals.”

Princeton Hydro’s Dam Removal Expert Laura Wildman, P.E. and Fluvial Geomorphologist Paul Woodworth are proud contributors to the book, helping to write the dam removal chapter, creating a dam removal flow chart for the book, and providing multiple photos utilized in the book. Princeton Hydro is also listed as a contributing sponsor.

“We’re so proud to be part of this incredible project with so many partners globally,” said Wildman. “We envision that this book will provide a valuable resource and inspiration for those in countries and regions where the importance of restoring riverine connectivity is newly gaining momentum. We hope it will help emphasize the importance of finding balanced and environmentally informed solutions when proposing additional utilization of public trust resources such as rivers.”

Approximately 40% of all fish species in the world reside in freshwater ecosystems, contributing economic and ecological benefits and value. It’s critical that we support efforts that aim to protect migratory fish species, reconnect rivers, sustain fish passage, and preserve free-flowing rivers through removing unnecessary dams, reconnecting floodplains, managing our water use, and managing hydropower for sustainable rivers.

Education and awareness building are key first steps in protecting rivers. From Sea to Source 2.0 seeks to inform, educate and inspire those who want to know more about how to meet the challenges of restoring fish migration in rivers around the world.  The book is regarded as a crucial resource in the ongoing fight to protect and preserve the enormous value of our waterways.

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

Credit: NPS.gov

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.

Princeton Hydro Dam Removal Work Featured at Brazilian Workshop

As Brazil is in the midst of a dam-building boom, scientists and engineers gathered at a workshop in Brazil to discuss, “Dam Removal & Optimizing Hydro Locations to Benefit Species Diversity in Brazil.”

Laura Wildman, P.E., Water Resources and Fisheries Engineer and Director of Princeton Hydro’s New England Regional Office, was invited to speak at the workshop. Her presentation focused on why we remove dams in the U.S. (the key drivers), how we analyze them for removal, and what we are learning through a wide diversity of completed case studies.

“It was fascinating to discuss a topic, such as the removal of dams, right as Brazil is focusing on building more hydro capacity,” said Laura. “Hopefully it is a sign that the hydro industry in Brazil, along with all the great Brazilian fisheries researchers, are quite forward thinking and are determined to maintain their country’s rich species diversity while also enhancing their energy options.”

The workshop, hosted by CEMIG and held at UFMG, involved many universities, including our workshop host Paulo Pompeu from UFLA, Dr. Paul Kemp from University of Southhampton, Dr. Jesse O’Hanley of Kent Business School, and many others.

The gathering inspired a lot of interesting dialogue around dam removal, optimizing locations for new hydro facilities, and how to best sustain connectivity and species diversity. Laura’s presentation entitled “Dam removal in the United States” along with the other conference presentations will be available on the CEMIG website soon or check back here on the Princeton Hydro blog for presentation links.

Princeton Hydro Participates in Rutgers Engineering Honors Council Competition

Princeton Hydro President Geoff Goll, P.E. participated as an alumni judge in the Rutgers Engineering Honors Council (REHC) Annual Case Competition.

The REHC Case Competition is an annual event in which students are given a case detailing a Rutgers-related issue and have a limited amount of time to analyze the case problem, develop a solution, and present their plans to a panel of alumni judges.

The judges critique the group and individuals on presentation, creativity, participation, feasibility of solution, and additional criteria. The competition is divided into two tiers, where the winners of each grouping of presentations then present to determine a final winner.

Over the past three years, more than one hundred students have participated and have included deans, alumni, administrators, and faculty in the development of the competition. This year, the judging panel incorporated four alumni, including Goll, who judged separate groups of three teams, and then joined together with the other judges to critique the final round of presentations.   

“It was a truly wonderful experience,” said Goll. “It’s so encouraging to see such eager and bright young minds that are on their way to becoming future engineering leaders.”

REHC, founded in 2011, is composed of Honors Academy and Honors College representatives and honor society presidents to provide a uniform voice to all sectors of the honors community in the School of Engineering. Students find unique opportunities to be mentored by industry professionals, engage with successful alumni, and exchange talents with their peers. 

Goeff Goll, Civil Engineering Class of 1990, brings extensive experience in water resources and geotechnical engineering to the table. He is highly experienced in stream restoration, dam removal, the design of large retaining structures, and building foundations and stormwater management systems.

 

Princeton Hydro President Gives Keynote Address

Princeton Hydro President Geoff Goll, P.E. gave the keynote address to kick-off the University of Wisconsin-Madison‘s Master of Engineering Management (MEM) 2017 Residency for 1st and 2nd-year students.

As a 2013 graduate of the MEM program and a leader in the industry, Geoff was invited to give the presentation and offer to students his perspectives, insights and advice on how to transition from being a technical expert to a role in leadership and management.

A personal message from Geoff:
“I was very honored to present to the students and faculty of the MEM program, as they are a prestigious group of professionals that represent many sectors in the engineering industry. The MEM program provided me with the tools to develop as a manager and leader at my firm, and I was very glad to be able to give back by sharing my experiences. I was also very excited to share the story of the firm’s history, which Dr. Stephen Souza, Mark Gallagher and I built from a small 7-person firm started in Steve’s attic, to the multi-state, nearly 50-person firm we are today.”

The UW-Madison College of Engineering ranked in the Top 20 Online Engineering Management Degree Programs. This 30-credit hour, cohort-style program is designed for mid-career engineers, focusing on how to strengthen the skills and develop the knowledge needed to lead organizations, teams, and resources in the engineering field. Each summer, students are required to participate in a weeklong residency course on the Madison campus to conclude summer coursework and lead into the fall courses.

The Restoration of Bound Brook

To the delight of fish and environmentalists alike, an important step has been made in the removal of the aging spillway of Hunters Pond Dam in Scituate and Cohasset, Massachusetts. The spillway was notched to ensure a gradual release of water from the impoundment, letting Bound Brook flow free again after being dammed for centuries.

As the first barrier upstream from the Atlantic Ocean, the dam’s removal restores 5-miles of river spawning ground and habitat for alewife, blueback herring, American eel, rainbow smelt, sea lamprey and other important species. The removal of Hunters Pond Dam also reduces the threat of dam failure.

Princeton Hydro is proud to be working on this project with T Ford Company, U.S. Fish and Wildlife Service, and many other great partners. The project is funded by grants from the Massachusetts Department of Ecological Restoration and the NOAA.

The project also includes rebuilding a culvert, removing a concrete spillway, and replacing a water main. Stay tuned for more!

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.

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.
