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…

Saturated, Suffocated, and Salty: Hotspots of Dissimilatory Nitrate Reduction in Anoxic Riparian Soils

800 532 Stroud Water Research Center

This project investigates the origin of the nitrogen stored in the riparian soils above milldams, the dominant processes controlling its transformation, and its risk of being released into the stream.…

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…

Recovery of Nutrient Processes and Microbial Communities in Relict Hydric Soils Following Restoration

800 532 Stroud Water Research Center

This research explores how microbes and biogeochemical processes in buried relict soils evolve after restoration and how these organisms and processes can be harnessed to remove nitrogen before it pollutes…
