Aqueduct withdrawals at the Little Falls intake caused a drop in flows at the Little Falls gage; flows should recover sometime later today. Flows at the Point of Rocks gage remain steady. An artificially varied flow is scheduled to be released from Jennings Randolph Reservoir today and should temporarily raise flows during the next couple of days.
Trace amounts of precipitation occurred above the Point of Rocks gage yesterday. However, most of the basin received no rain in the last 24 hours. Both the 48-hour forecast from the River Forecast Center and the 5-day National Weather Service QPF are predicting no accumulated precipitation over their respective forecast periods in the Potomac basin.
