Lake Data

Lake inflows have fallen for the past 7 days and have not been enough to recharge the lake's volume since July 13th.  The lack of rain and declining flows in the river and creeks have led to daily drops in the water level.


Water intake for processing has been higher in the few days to provide adequate intake for maintenance purposes.  The water taken in above the level we will need to support community use will be returned to the river below the dam and credited against our mandatory release as they are not needed.

Lake Data

Inflows continue to fall below the level we need to maintain the lake level (~285 cfs/180 mgd).

Lake Data

The table below shows basic lake level, inflows and outflows for the past 7 days.
Inflows have been dropping off and fall below the level where we are able to maintain the lake's current level and still meet our commitments.
