April 29, 2011 Update

Elevation               Change from April 15, 2011               Summer Max
 
Mendota         850.15                   +0.08 ft                    +0.05 ft
Monona          845.32                   +0.30ft                     +0.12 ft
Waubesa         844.94                   +0.33 ft                   -0.06 ft
Kegonsa         843.36                   +0.31 ft                    -0.14 ft
 
We have received 3.6  inches of precipitation since April 1, 2011.  This compares to a normal of 3.13 inches.
 
We have increased flow through the Tenney Dam as a result of increased flow coming in to Lake Mendota.  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.
 
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.
