May’s Water Supply Outlook is Out

The low groundwater levels and the recent lack of spring rain have increased the likelihood of water being released from backup reservoirs in the Washington metropolitan area during this summer and fall seasons. Despite receiving some rainfall at the end of April, the cumulative precipitation in the basin over the last 12 months remains below normal.

Currently, the Potomac River flow is sufficient to meet water demands without upstream reservoir releases. However, a prolonged dry spell could lead to hydrological drought. In the case of a drought, the region has contingency plans in place to manage water supply shortages.
