American River Group Handouts

Posted on Monday, April 24th, 2017

Reclamation released flow projections for April through September for the lower American River at the monthly ARG meeting 4/20/17.  Peggy noted that the lower two shutters are in place for the two working penstocks. The third penstock is out for maintenance and is expected to be back online soon with the lower two shutters. They are having difficulties with the upper shutter because of debris.

Five water monitoring stations were damaged during the high water.  They are expected to be repaired/relocated by the end of April.
