Water Supply

CO-OP Section
The Section for Cooperative Water Supply Operations of the Interstate Commission on the Potomac River Basin (CO-OP) was created to coordinate water supply operation of the three independent water suppliers in the Washington D.C. area during times of drought. CO-OP makes releases from regional reservoirs to ensure that minimum environmental flow requirements and water supply withdrawals can be met. In non drought years, CO-OP works closely with member utilities to conduct annual drought preparedness exercises to keep operations crisp.

Future challenges for the section include evaluating water supply alternatives for meeting future demands, monitoring ongoing drought conditions and status, and developing improved modeling and analysis tools for the Potomac watershed including field data collection.

Groundwater
A basin-wide groundwater assessment has been initiated to evaluate the availability of groundwater resources in the Potomac River basin. This project is being carried out in close cooperation with the USGS and includes the installation of real-time monitoring equipment at groundwater wells throughout the basin as well as database development and data analysis work.
