USGS Role in Water Quality: Nutrients and Sediment

Photo collage of bridge and sediment in river

Chesapeake Bay Program (CBP) partners are working to reduce nutrients and sediment to improve dissolved oxygen, water clarity, chlorophyll conditions in the Bay, and the health of streams. The Watershed Agreement has specific outcomes to improve water quality in the Bay, which is being addressed through the Bay Total Maximum Daily Load (TMDL), and to restore stream conditions in the watershed.

The U.S. Geological Survey (USGS) is providing science, using an adaptive-management framework, to help the CBP partnership more effectively prioritize, monitor, and evaluate the effects of practices designed to reduce nutrients and sediment. The USGS will help meet these needs in three ways:

The USGS is enhancing water-quality models so partners can better understand water-quality conditions and target practices where they will provide the most benefit. The primary USGS models include:

The USGS is expanding regional monitoring and the explanation of water-quality changes so that partners can better assess progress toward nutrient and sediment reduction goals. The USGS efforts will include:

The USGS is working to monitor and assess changes in small watersheds and provide implications about the effectiveness of management practices. The USGS efforts include:
