River and Rain Report

The Potomac River watershed has had a dry winter. The region above Little Falls has received 3.2 inches below average of rain since November.

After weeks of frigid temperatures, ice is now breaking up in the river and we are able to see the flow on USGS gages. The blue block on the graph below indicates no data due to ice. The flow (blue line) at Point of Rocks is 3330 cubic feet per second (cfs). The median (gray line) for this time of year is 8500 cfs.

Today’s U.S. Drought Monitor map for the Potomac River basin shows 75% of the area is in Moderate Drought conditions and 12% is in Sever Drought (mostly the south eastern section of the watershed). The remainder is Abnormally Dry. This is an increase in Moderate Drought conditions over last week’s map.

It is predicted that we will receive 0.25-1.5 inches of rain over the next 3 days, with the heavier amounts in the area that needs it most, the south eastern region of the watershed.

The DC metropolitan area remains in the Drought Watch declared by the Metropolitan Washington Council of Governments (COG) back in July. Officials are asking everyone to use water wisely during this time. The COG Drought Coordination Technical Committee will convene on March 7 to evaluate the drought declaration.
