Will Removing Thousands of Old Milldams Across the Northeast Help or Hurt Streams?

800 450 Stroud Water Research Center

Stroud Center scientists have been assessing how milldams affect the filtering capacity of streams and whether their removal affects water quality. 

Water Quality Modeling to Support Source Water and Aquatic Life Protection in Octoraro Creek Watershed

800 532 Stroud Water Research Center

This project supports water quality monitoring and development of a water quality model to guide an alternative restoration plan for the Octoraro Creek Watershed. The data, model, and plan will…

Restoration Project Impact Assessment in Support of Delaware River Watershed Initiative

800 532 Stroud Water Research Center

This project quantifies the positive impacts of restoration projects on water quality and soil health associated with the Delaware River Watershed Initiative. (Project details may change over the lifespan of…

Mitigating Agricultural Pollution of Fresh Water and Combating Climate Change by Restoring Soil Health

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.…

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

800 532 Stroud Water Research Center

As dam removal has increased in recent years in an effort to improve fish habitat and reduce financial liability, few studies have addressed the consequences of these removals for water…

Long-Term Research in Environmental Biology: 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. To fill this gap, the Stroud Center restored a portion of…

Evaluating the Effects of Watershed-Scale Agricultural Best Management Practices on Water Quality

800 532 Stroud Water Research Center

In early 2020, stream bank fencing, forested buffers, and barnyard improvements were installed on Amish farms in Lancaster County, Pa. The farms are nested in a small watershed drained by…
