Except for scattered amounts of trace rainfall yesterday, the basin has not received any precipitation over the past 7 days. The National
Weather Service predicts no precipitation in the basin over the next 48-hour period. A small amount of rain, up to 1/10 of an inch, is
being forecasted to fall in the North Branch area within the next five days. It appears that the artificially varied flow (AVF) release from
Jennings Randolph has reached Little Falls causing increased flow at the gage. It is expected that flows will drop again once the AVF
passes by over the weekend. Daily monitoring will continue over the holiday weekend.
