Current Drought Conditions

As part of the Metropolitan Washington Water Supply and Drought Awareness Response Plan, COG issues monthly drought reports from May - October. COG also encourages wise water use throughout the entire year - visit the outreach and education website for water conservation tips.

Summary of Conditions- June 6, 2017

The COG region received an above average amount of rain in May, and as a result, is drought free. Local reservoirs are full, and regional groundwater and streamflows are currently near median levels. Drought status conditions in Maryland and Virginia are improving although some watches and warnings are still in effect.

In Maryland, as of April 30, 2017, the Central region remains in drought Warning. The Eastern region's drought status has moved from Normal to Watch. In the Central region, over the last 30 days rainfall and stream flow conditions have improved, but the ground water indicator remained unchanged.

On March 20, 2017, the Virginia Department of Environmental Quality issued a drought watch for Northern Virginia public and private water supplies using groundwater and private water supplies using surface water. Water systems using the Potomac River or Occoquan Reservoir are not affected at this time.  As of June 5, 2017, VADEQ’s drought watch is still in effect. Abundant precipitation during the first part of May reduced or eliminated dry conditions over most of Virginia.  However, portions of Northern Virginia, especially those areas within the Northern Virginia and Northern Piedmont drought evaluation regions, continue to experience dry conditions.  Groundwater levels and water-year-to-date precipitation totals in these areas remain below normal levels.
