No change in the weather forecast. Without additional rain, flows may begin to drop in the near future. The recent drop in Little Falls flows is likely due to the load shift by Washington Aqueduct.

The rain falling across the basin today is helping to maintain flow
levels and, along with a drop in demands, is keeping utility
operations steady. The releases from the North Branch reservoirs
continue. The leading edge of the release can be seen at the Paw Paw,
WV gage on the mainstem Potomac River.
Washington Aqueduct will go off of the Little Falls pumping station
and back to Great Falls when possible. They were unable to reach the
station earlier in the day due to the triathlon taking place in the
area.
Potomac River flow at the USGS's gage station at Little Falls is now in the vicinity of 300 MGD. There may be some relief from the dry weather this weekend; the National Weather Service predicts accumulations of up to 1/2 inch of rain throughout much of the basin today and tomorrow. The release from the North Branch reservoirs will continue through the weekend.
