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 been the primary motivators for dam removal, few studies have addressed the consequences of these removals for water quality and regulatory compliance. This project investigates the role of low-head milldams on nitrogen and sediment transport in stream ecosystems.
