Stream flows continue to fall throughout the basin. Yesterday's daily mean flow at Little Falls was 890 MGD (1370 cfs). The July 4th whitewater release is almost past Point of Rocks, and should be arriving at Little Falls today - producing a short-term uptick in flow.
MARFC's observed precipitation maps indicate that there were scattered thunderstorms in the basin over the past 24 hours, with accumulations
of 1/2 to 1.5 inches in a few localized areas. MARFC predicts accumulations of over an inch throughout much of the basin in the next 48 hours.
Because of uncertainty about next week's flow conditions, we will continue daily monitoring throughout this weekend.
