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!

Princeton Hydro Team Trained in USACE MII Cost Estimating Software

Congratulations to Amy McNamara and James Hunt of Princeton Hydro who received their certificates of completion for the in-depth training of the October 2017 MCACES (Micro-Computer Aided Cost Estimating System), 2nd Generation (MII) Training Course in Atlanta, Georgia. MCACES is an integrated cost estimating system that meets the U.S. Army Corps of Engineers (USACE) requirements for preparing cost estimates for civil works projects.

This 32-hour course provided an in-depth look at the software application and its components which are used to build detailed construction cost estimates. In a classroom setting, Amy and Jim learned how to prepare and execute computerized cost estimates using parametric worksheets, quantity linking, and assemblies. Our engineering team now has the capability to navigate through the MII software and libraries to create a project, cost items, crews, labor and equipment. Amy and Jim understand how to work with database functions to create site-specific unit prices, modify equipment costs for project specific circumstances, and adjust crew for overtime and shift differential.

Now being used by many of the USACE districts, it will soon be a requirement for all USACE districts to use MII, as well as all architect-engineering (A-E) firms performing design work for the USACE.

“We are looking forward to using the program to help our Federal partners meet their mission objectives,” stated Geoff Goll, President of Princeton Hydro. “The completion of such training efforts continues our commitment to supporting the U.S. Army Corps of Engineers’ efforts in the North Atlantic Division and beyond.”

Barnegat Bay Green Infrastructure Project Named “Project of the Year”

Princeton Hydro is thrilled to announce that American Littoral Society’s Barnegat Bay Green Infrastructure Project has been named “Project of the Year” by The American Society of Civil Engineers Central Jersey Branch.

The award-winning project was a collaboration between the Littoral Society, Princeton Hydro and key partners that involved implementing a variety of green infrastructure stormwater management projects in order to decrease the volume of runoff and associated pollutants flowing into and damaging Barnegat Bay.

The green infrastructure projects were designed to treat stormwater at its source while delivering environmental, social and economic benefits to the Bay. Completed projects include:

  • Conversion of standard, grassed detention basins into naturalized bio-retention basins, as exemplified by the Laurel Commons Carnation Circle Basin, which now serves as a paradigm for the cost-effective retrofitting of aged, traditional detention basins
  • At Toms River High School North, the installation of tree boxes,
  • At the Toms River Board of Education offices, the replacement of conventional paving with permeable pavement,
  • At multiple sites, the construction of rain gardens,
  • At Toms River High School North, the construction/installation of stormwater management Manufactured Treatment Devices (MTDs)
  • At the Toms River Community Medical Center (RWJ Barnabas Health), the construction of a bio-retention/infiltration basin

The entire Princeton Hydro team extends our warmest congratulations to Helen Henderson and all of the folks at American Littoral Society for winning this prestigious award! Princeton Hydro is proud to partner with this incredible organization and is grateful for the work they do to protect our beautiful coastline and save the bay!

The Awards Dinner and celebration takes place on Tuesday, October 17th at the Forsgate Country Club. The “Project of the Year” nomination was originally submitted by Princeton Hydro founder Dr. Stephen Souza on behalf of the Littoral Society.

Green Infrastructure Planting Projects

The Princeton Hydro team has been busy this summer installing over 1700 plants at three of the company’s green infrastructure stormwater management project sites.

First, team members finalized the planting of two rain gardens located at Clawson Park in East Amwell, NJ. They also installed plants in a renovated detention basin located at the West Amwell Municipal Building. Finally, together with members of the American Littoral Society team, the team finalized the planting of an expanded rain garden and a newly constructed bio-infiltration planter box at Toms River High School North, Toms River, NJ. All three projects are 319(h) funded projects.

Everyone dug-in, got their hands dirty and the payoff to all of this planting is less runoff and less pollutant loading to our streams and rivers!

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!
