No precipitation fell in the Potomac basin over the past 24 hours. The National Weather Service predicts little rain over its 5-day forecast period, but the trajectory of Hurricane Earl is uncertain, and it could have an impact on the basin. Last weekend's AVF water quality release from Jennings Randolph Reservoir should be arriving at Little Falls on Friday. Note: yesterday's daily mean flow values are not available for many Potomac basin gages, including Point of Rocks and Little Falls, so values given below for 8/30 are estimated from available real-time data.
Daily Flows:
Little Falls gage flow 08/30: 720 MGD (1120 cfs)
Little Falls gage flow 08/31: 840 MGD (est., based on recently available real time data) (1300 cfs)
Note: Gage flow at Little Falls is measured after water supply withdrawals.
Point of Rocks flow 08/30: 970 MGD (1500 cfs)
Point of Rocks flow 08/31: 920 MGD (est., based on recently available real time data) (1420 cfs)
