Maryland-Delaware-D.C. Water Science Center
Home
Welcome to our Water Science Center! Water resources of Maryland, Delaware, and the District of Columbia consist of numerous streams, springs, lakes, and aquifer systems. Streamflow, groundwater levels, and water-quality data are collected at numerous locations, and water-use data are collected throughout the area in cooperation with other federal, state and local agencies, universities, and research centers. Feel free to examine the hydrologic data we collect and the scientific investigations we conduct at the MD-DE-DC Water Science Center.
Chesapeake Bay Activities
The USGS has the critical role to provide scientific information for the improved understanding and management of the Bay ecosystem. The USGS works with Federal, State, and academic science partners to provide research, assessment, and monitoring.

Ecological forecasting—21st century science for 21st century management
Natural resource managers are coping with rapid changes in both environmental conditions and ecosystems. Enabled by recent advances in data collection and assimilation, short-term ecological forecasting may be a powerful tool to help resource managers anticipate impending near-term changes in ecosystem conditions or dynamics. Managers may use the...

Monthly suspended-sediment apportionment for a western Lake Erie agricultural tributary
Black Creek, a headwater to the Maumee River and western Lake Erie, is an agricultural basin with a mix of cropland (66%), pasture (19%), and forest (7%) linked by a road network to the rural community. Suspended sediment was collected monthly during the 2018 water year for the main stem and two sub-basins using in-situ, passive samplers that...
