Monitoring Fish Populations and Stream Habitat Quality for the National Park Service

800 532 Stroud Water Research Center

This project monitors biological conditions, water quality, habitat integrity, and fish at 37 sites in 10 national parks in the National Capital Region Network around Washington, D.C. The findings of…

Molecular Ecology of Archaea in Aquatic and Terrestrial Environments

800 532 Stroud Water Research Center

Less is known about Archaea than the other two domains of life on Earth (Bacteria and Eukarya), particularly the role they play in ecosystem functions and nutrient cycling (e.g., ammonia…

Model My Watershed — Delaware River Basin

800 532 Stroud Water Research Center

This project expands the Model My Watershed® application to the entire Delaware River Basin and supports restoration efforts funded by the William Penn Foundation. This application will provide higher-resolution modeling…

Mitigating Agricultural Pollution of Fresh Water and Combating Climate Change by Restoring Soil Health Through Conservation and Organic Agricultural Practices

800 532 Stroud Water Research Center

Plowing, disking, synthetic fertilizers, and pesticides have damaged the health of agricultural soils, resulting in reduced rainfall infiltration and storage, increased stormwater and pollutant runoff, degraded streams, and contaminated groundwater.…

Microbial Population Dynamics of Periphyton Biofilms in White Clay Creek

800 532 Stroud Water Research Center

Using glass microscope slides as tiny gardens to grow microbial biofilms, this project explored differences in microorganisms between three reaches of White Clay Creek with different streamside vegetation. Molecular DNA…

Macroinvertebrate Monitoring at Sites in White Clay Creek, Pa., Flint River, Ga., Susquehanna River, Pa., and Delaware River, Pa.

800 532 Stroud Water Research Center

These projects use aquatic macroinvertebrates such as mayflies, stoneflies, and caddisflies to provide assessments of current water quality in these streams and rivers.

Low-head Milldams as Hotspots for Denitrification and Nitrogen Consumption: Hydrologic and Biogeochemical Controls

800 532 Stroud Water Research Center

Dam removal, especially low-head milldams, have increased in recent years with the highest removal rate in the mid-Atlantic U.S. While improvement in fish habitat and reduction in financial liability have…

Ecotoxicity Study for Mayflies Exposed to Elevated Concentrations of Chloride at Different Temperatures

800 532 Stroud Water Research Center

Chloride concentrations in surface waters have been increasing over the last several decades at multiple locations throughout the United States. At times, it appears that ambient chloride concentrations now reach…

Delaware River Watershed Initiative — Phase II Monitoring, Evaluation, Scientific Support, and Capacity Building for Watershed Protection and Restoration Projects

800 532 Stroud Water Research Center

This project collects and interprets data on macroinvertebrate specimens from stream sites to provide a baseline for the evaluation of goals defined for restoration and protection projects funded by the…

Delaware River Watershed Initiative — Phase II Monitoring, Evaluation, and Scientific Support for Protecting and Restoring Places of Ecological Significance (Brandywine-Christina, Middle Schuylkill, Schuylkill Highlands Clusters)

800 532 Stroud Water Research Center

Professional and volunteer monitoring of chemistry, macroinvertebrates, and fish to support restoration and protection efforts represent an invaluable (and often neglected) tool to evaluate short- and long-term progress toward conservation…
