May 13, 2011 Update

                     Elevation       Change from 4/29/2011    Summer Max
 
Mendota         849.95             -0.20 ft                            - 0.15 ft
Monona          845.37            + 0.05ft                            +0.17 ft
Waubesa         844.91            -0.03 ft                            - 0.09 ft
Kegonsa         843.18             -0.18 ft                            - 0.32 ft
 
We have received 7.62  inches of precipitation since March 1, 2011.  This compares to a normal of 6.86 inches.
 
We are holding flow out of  the Tenney Dam steady.  As Lake Monona declines, we will continue to increase flow from Lake Mendota to Monona. 
 
Babcock County Park Lock and Dam remains completely open in full flow condition, since last April.
 
We will continue current flow out of the Lafollette Lock and Dam.  However, as Lake Kegonsa is below mid range, we may slowly reduce flow to keep the lake within its' respective range.
 
The current strategy is to get all lakes to their respective Summer Permit Range.  Pending total precipitation and runoff this weekend, we will continue to move water out of Lake Mendota, at a rate that we can safely pass through Lake Monona.
 
Once all lakes are in range, we will begin to stabilize flows, to get each lake to their mid range level.
