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.

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!

Truxor DM 5045 – The Newest Addition to the Princeton Hydro Family

Truxor DM5045 Stock Image We’re thrilled to announce the arrival of our new Truxor DM 5045!

This multi-functional, eco-friendly, amphibious machine effectively controls invasive weeds and problematic algae growth without the use of pesticides.

Its light-weight construction and highly advanced weight distribution system provide low ground pressure and high floating capacity. This allows the Truxor to operate on water, in deep or very shallow depths, and on dry land without disrupting sensitive environments, like nature preserves, wetlands, canal banks, golf courses and areas that are difficult to access with conventional equipment. And, the Truxor’s highly maneuverable and precise control system ensures easy passage through narrow channels and around hazards.

Equipped with a wide range of tools and accessories, the Truxor DM 5045 can perform a variety of functions, including weed cutting and harvesting, mat algae and debris removal, silt pumping, dredging, channel excavation, oil spill clean-up and much more!

This is the second Truxor to be welcomed to the Princeton Hydro family, which also includes a Marsh Master, another versatile, fully amphibious vehicle. Watch our Truxor DM 5000 in action.
