New high-resolution, land-use and change data improves decision-making in the Chesapeake Bay watershed
Efforts are underway to protect the rich array of lands and habitat across the Bay watershed for fish, wildlife, and people. However, new high-resolution data show an alarming loss of forests and other vital lands because of development. The USGS is leading analyses of the enhanced land-change data, and forecasting scenarios of future use, to inform land-protection and local-planning decisions.

USGS develops novel approach to assess efficiency of stormwater management practices
Issue: Urban stormwater runoff is a rapidly increasing source of pollutants to Chesapeake Bay. It contributes on average 16 percent of the nitrogen, 16 percent of the phosphorus, and 25 percent of the sediment load to the bay annually. Urban stormwater best management practices (BMPs) (fig. 1) have been used in an effort to reduce the volume and improve the quality of stormwater runoff entering...
