Welcome to the latest edition of our Client Spotlight series, which provides an inside look at our collaboration, teamwork, and accomplishments with one of our client partners.
Today, we’re shining the spotlight on Citizens United to Protect the Maurice River and Its Tributaries, known commonly as CU Maurice River, a 501(c)3 nonprofit membership organization dedicated to protecting the Maurice River Watershed’s natural integrity and cultural heritage.
The Maurice River, located in south-central New Jersey, was designated a National Wild and Scenic River by Congress in 1993. It draws from a drainage area of 385 square miles and meanders south for 50 miles, through Southern New Jersey primarily in Cumberland County. Headwaters are in parts of Gloucester, Salem, and Atlantic Counties, emptying into the main stem of the Maurice; from there it flows into Delaware Bay. The major tributaries of the river are Scotland Run, Muddy Run, Menantico Creek, Muskee Creek, and the Manumuskin River. There are about 20 small lakes in the watershed, the largest of which is Union Lake at 950 acres.
[gallery link="none" ids="17583,17586,17584"]
As South Jersey’s leading watershed organization, CU Maurice River engages in fieldwork, advocacy, research, and education initiatives generating and contributing to a greater understanding of the local environment and wildlife.
For this Client Spotlight, we spoke with CU Maurice River Executive Director Karla Rossini via Zoom:

Q. Tell us a little about CU Maurice River and what makes it unique?
A:

"CU Maurice River is a very grassroots, very local organization. One of our core strengths is community involvement. In everything we do, we try to invite the largest section of community that we possibly can. Whether that’s to participate in educational opportunities or participate in volunteerism or become an advocate of our local resources, we really make it our goal to develop and foster stewardship within the community."




Q. What are some exciting things your organization is working on right now?
A:
"We're very excited about the work we're doing with the WheatonArts & Cultural Center, a nonprofit 501(c)(3) organization with a mission to engage artists and audiences in an evolving exploration of creativity.
Over the years, CU Maurice River has worked with WheatonArts to design and implement various best management practices throughout its 45-acre campus. We’ve installed vernal pools, purple martin gourds, a blue bird trail, a nature trail, and a massive rain garden. The projects support water resources on site and beyond, revitalize and preserve natural habitats, and provide an invaluable community resource for promoting eco-friendly land management, stewardship, and nature exploration.
WheatonArts and CU Maurice River also launched a four-week nature journaling course, which will take place on Wednesdays and Thursdays, from August 3 to August 25 (2023). Kids get to spend time outdoors while growing their science knowledge, appreciation for nature, and artistic ability. Nature journaling is a way to creatively connect and build a deep, lasting relationship with the natural world.
The CU Maurice River team does the scientific teachings, and the WheatonArts team does the art teachings. So for example, CU Maurice River will teach about the anatomy of a tree, how a tree functions, why an Oak tree produces acorns, and the ecosystem services a tree provides. And, WheatonArts teaches the kids how to draw and paint a tree, how to make an acorn look round, and how to get the shades of the brown tree trunk just right.
Another interesting aspect of the program is that it also highlights the history of communication in nature exploration. Darwin had to draw his pictures to describe his findings. Mary Treat had to draw her discoveries. Audubon had to illustrate his birds. And, let’s face it, most of the best ID books aren’t photo books, they’re illustrated books. So, this program focuses on the importance of art in science."




Q. Can you talk a little about the CU Maurice and Princeton Hydro partnership: 
A: 
"The first time I encountered Princeton Hydro was at a Musconetcong River event where Princeton Hydro was presenting on dam removal and the restoration of trout habitat on the Musconetcong. Then, later that year, at the Annual Delaware River Watershed Forum, I met Dana Patterson (Princeton Hydro's Director of Marketing and Communications). We got to talking about a variety of different projects we could explore together, and it's been a really great partnership ever since. I’m pretty sure I've given Dana and Christiana Pollock (Princeton Hydro's Director of Restoration and Resilience) some wacky ideas to figure out, but Princeton Hydro has always been very supportive AND realistic.
Since then, we’ve contracted with Princeton Hydro to do a feasibility study on the Centerton Dam removal. We’re also working with Princeton Hydro to do an ArcGIS StoryMap of the Paddle Trails in the Maurice River Watershed. And, we've got some other exciting things in the works that I'm not at liberty to discuss publicly today, but stay tuned for more great things as a result of CU Maurice River's collaboration with the Princeton Hydro team.
Princeton Hydro has really provided a lot of support and guidance, and I am eternally grateful for their partnership."

For episode three of Stroud Water Research Center's 2022 Science Seminar Series, Michael Hartshorne, Director of Aquatics at Princeton Hydro (and former Stroud Center intern), gave a presentation about the ecological status of the Schuylkill River and shared the story of a yearlong community science project that included a volunteer survey and scientific water quality assessment. Stroud Center's Science Seminar lecture series, which provides an opportunity for the public to learn more about the issues that matter to them, has been running for over a decade. It also gives the public access to some of the world’s leading freshwater scientists and educators and the chance to learn how watershed science and education are tackling water-related challenges.
As described in Michael's presentation, the project, which included four phases, was implemented through a partnership between the Schuylkill River Greenways, Berks Nature, Bartram’s Garden, The Schuylkill Center for Environmental Education, Stroud Center, and Princeton Hydro.
First, to understand local perceptions of the river, investigators conducted a community survey of more than 300 residents from Berks, Chester, Montgomery, and Philadelphia counties. Despite a majority of respondents reporting that they care about the river, many also reported concerns about trash and litter and whether the river is clean and safe enough for activities like swimming and fishing. This insight was used to drive the priorities for the in-depth water quality monitoring assessment and inspired the launch of a new Community Science trash monitoring program.
In June, the group launched an interactive ArcGIS StoryMap webpage that reveals the local perceptions of the Schuylkill River and aims to connect residents and communities with the Schuylkill River and encourage engagement with this special resource.

This year marks the 50th anniversary of the Clean Water Act. In celebration, The Watershed Institute launched its “Watershed Wednesdays” webinar series, which explores a variety of topics related to the environmental laws that arose after the Clean Water Act was instated. The webinars are free, open to the public and occur on the 3rd Wednesday of each month between 6 - 7:15pm EST.



To kick-off the Watershed Wednesdays series, three experts from the Princeton Hydro team led a workshop about “Stream Bank Restoration in Communities & Backyards,” which included three presentations and a Q&A session. Participants learned about what they can do to improve the water quality and restore the natural function of their neighborhood streams. Scroll down to watch the full webinar! 















In the first presentation, Water Resources Engineer, Jake Dittes, PE, provides an overview of streams, how they flow, they’re natural evolution, how they’re being impacted by climate change, and the dynamic connection between land and water. Jake provides simple action items that everyone can do to reduce stormwater flow, limit runoff pollutants, boost and protect the natural floodplain.



Casey Schrading, E.I.T., Staff Engineer, shares examples of degraded stream systems, discusses a variety of restoration techniques, and talks about his experience with overseeing the largest stream restoration project completed in Maryland. He also provides helpful tips and examples of what individuals can do in their own backyards to promote stream bank stabilization.



The third presentation is given by Landscape Architect, Cory Speroff, PLA, ASLA, CBLP. In it he provides an in-depth look at a stream, floodplain and multi-functional riparian buffer restoration project Princeton Hydro completed at Carversville Farm in Western Pennsylvania. And, he provides an in-depth look at the native plants that were installed in various zones throughout the farm and how the different plants help reduce stormwater flow, absorb excess nutrients, and prevent erosion.

The Resource Institute hosted its 9th Annual Mid-Atlantic Stream Restoration Conference in Baltimore, Maryland, where water resource professionals, researchers, and practitioners come together for three days to share ideas and learn about stream restoration planning, assessment, design, construction, evaluation, and other topical stream issues. The conference, which was themed Building Resilient Streams in the Mid-Atlantic and Northeast regions, included presentations, discussions, exhibits, and pre-conference workshops. Princeton Hydro participated in three presentations on a variety of topics. Below, we provide a synopsis and free download of each presentation:

Innovative Design and Funding Approaches for Dam Removal Projects Where an Unfunded Mandate Exists


Lead Presenter: Kirk Mantay, PWS, GreenTrust Alliance, Inc.
Co-Authors: Geoffrey Goll, P.E.; Princeton Hydro President; John Roche, Maryland Department of Environment; and Brett Berkley, GreenVest.
The presentation provides a detailed look at the removal of the Martin Dam in Fallston, Maryland, and how project partners were able to drastically expand the footprint of this emergency dam removal to generate enough ecological restoration benefits to adequately fund the dam removal itself.
The Martin Dam was constructed in 1965 as part of USDA’s sustainable farms pond construction initiative, which promoted aquaculture and subsistence fish production on small farms across the region as an income source for agricultural producers. Dam-related impacts included the permanent loss of spring-fed sedge wetlands, ditching of forested floodplain wetlands, pollution from stream bank entrenchment, and thermal impacts to a wild brook trout population downstream.
Overtime, the dam structure began to degrade. With each state and local agency inspection that was conducted, the dam increased in hazard category. In 2016, the Maryland Department of the Environment (MDE) was forced to list the dam as a, “public safety hazard at risk of immanent failure.” The landowner, unable to fund the dam removal, contacted GreenTrust Alliance (GTA), a regional green infrastructure nonprofit organization, for help.
By emphasizing the ecological benefits of restored wetlands and streams above and below the dam as well as the critical public safety hazard faced by residents and motorists downstream, GTA, in partnership with Princeton Hydro and GreenVest, was able to secure restoration funding for the site. The design and permitting was lead by Princeton Hydro, and the dam was safely breached as part of restoration construction in January 2019.

Columbia Lake Dam Removal; Using Drones for Quantitative Evaluation of River Restoration


Lead Presenter: Beth Styler-Barry of The Nature Conservancy
Co-Authors from Princeton Hydro: Geoffrey Goll, P.E., President; Casey Schrading, EIT, Staff Engineer; Kelly Klein, Senior Project Manager, Natural Resources; and Christiana Pollack, CFM, GISP, Senior Project Manager, Environmental Scientist.
In order to explore the use of drone or UAV technology to evaluate the effects of dam removals, the presentation showcases the Columbia Lake Dam removal, the largest dam removal in New Jersey to date.
The Columbia Lake Dam, built in 1909, was 18 feet high, 330 feet long dam, and stretched more than 1.5 miles on the Paulins Kill less than 0.25 miles upstream from its confluence with the Delaware River. As part of The Nature Conservancy’s (TNC) mission to improve the quality of the Paulins Kill, removing this “first blockage” was the cornerstone of the larger mission. Princeton Hydro served as the engineer-of-record, designing and permitting this project. Dam removal activities commenced in 2018 and were finalized in 2019. Its removal opens 10 miles of river for fish migration and improves recreation access, floodplain reconnection, habitat enhancement and higher water quality.
TNC will conduct five years of monitoring, a vitally important component of this project, to determine long-term ecological uplift, short-term positive and negative effects, and to develop data to provide information for future dam removals. And, as a result of the programmable and repeatable nature of drone flight paths, such monitoring will be able to be conducted for years and decades, producing invaluable data for research and future project design.
The presentation reviews the various parameters investigated, the results and significance of the data retrieved, and recommendations for the use of drone technology for future ecosystem restoration projects.

Modeling 3D Rivers in AutoCAD to Enhance Design and Deliverables


Lead Presenter: Daniel Ketzer, PE, Princeton Hydro Senior Project Manager, River Restoration
Co-Authors from Princeton Hydro: Eric Daley, Water Resources Engineer; Cory Speroff, MLA, ASLA, CBLP, Landscape Designer; and Sumantha Prasad, PE, ENV SP, Water Resource Engineer
This presentation provides an overview on how to create 3D river models based on geomorphic input to enhance the overall accuracy and quality of a river restoration project.
In river restoration, the proposed geometry of the river channel is the key part of the design. It impacts earthwork, utility conflicts, plan set layout, and many other aspects of the project. In larger projects with reaches measuring thousands of feet and greater, manual grading is extremely time consuming and tedious; and determining the entire implication of the proposed design is difficult to achieve when simply analyzing proposed cross-sections and profiles. To increase efficiency and maintain uniformity throughout the subject reach developing a 3D-surface model of the proposed restoration reduces design time and increases quality. AutoCAD Civil 3D can be used to convert the proposed profiles and cross-sections from a geomorphic design into a 3D surface of the river corridor.
The presentation goes through the key steps that need to be taken and strategic questions that need to be asked when modeling 3D rivers in AutoCAD along with important tips and reminders.

The Musconetcong Watershed Association (MWA) held its 26th Annual Musconetcong River Cleanup on April 14. Volunteers conducted cleanup efforts at various locations all along the Musconetcong River from its start at Lake Hopatcong down to where it meets the Delaware River. Princeton Hydro, a proud sponsor of the event, has investigated, designed and permitted five dam removals along the Musconetcong River.

Princeton Hydro led a volunteer team near the Warren Glen Dam site and former Hughesville Dam site. The team picked-up garbage along the road and riverbank, and pulled trash from the riverbed. In 2016, we designed and oversaw the Hughesville Dam removal and streambank restoration project, which enabled the return of American shad to the river for the first time in decades.
"We enjoyed the beautiful, warm, and sunny Saturday morning bonding with our Princeton Hydro colleagues and friends, while giving back to the Musconetcong Watershed Association," said Geoffery Goll, President of Princeton Hydro. "Our successful partnership with MWA on multiple dam removals in critical locations has expedited the restoration and protection of the Musconetcong River."

                    [post_content] => 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 President 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. Representing Princeton Hydro at the awards dinner were Vice President Mark Gallagher, his wife Jennifer, Geoff and his wife Amy, and Director of Engineering Services Mary Paist-Goldman, PE.

Here's 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!

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.
