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…

Brandywine Stream Stewards: Community Action in Support of Healthy Waters

1024 681 Stroud Water Research Center

The Stream Stewards Program engages adults and youth from Wilmington, Del., to monitor water resources in the 1,100 acres of open space in the First State National Historical Park. This…

Assessment of Environmental Conditions in Streams of the Runnymede Sanctuary Based on Physical, Chemical, and Macroinvertebrate Monitoring

1024 681 Stroud Water Research Center

The 1,670-acre Runnymede Sanctuary was created to preserve the extensive natural, historic, and scenic resources harbored by the property and to facilitate appropriate study and use of those resources. Its forests,…

Assessment of Environmental Conditions in Bennett’s Run at Kendal-Crosslands Based on Physical, Chemical, Macroinvertebrate, and Fish Monitoring

1024 681 Stroud Water Research Center

Bennett’s Run is a small tributary to Brandywine Creek in southern Chester County, Pa., where a watershed conservation plan is being developed. To inform this plan, this study is measuring…

Long-Term Research in Environmental Biology (LTREB): Trajectory for the Recovery of Stream Ecosystem Structure and Function During Reforestation

800 532 Stroud Water Research Center

Stream restoration in the United States is a multibillion-dollar industry. Yet long-term monitoring of its effectiveness is virtually nonexistent. Stroud Center scientists are studying restoration within White Clay Creek that…
