DES posted their final decision on the lake level yesterday. It calls for Waukewan to be at 540′ and a draw down to 538.5′ after Columbus Day.  The plan depends very heavily on quick and aggressive reaction by the dam operators to rain events in order to maintain this level.  Whether or not this is a reasonable expectation, time will tell.

Here is the full report:
