April 15th Update

 
                        Elevation               Change from April 1, 2011                Summer Min
 
Mendota         850.07                   +0.31 ft                               +0.47ft
Monona          845.02                   -0.07 ft                                +0.32 ft
Waubesa        844.61                   - 0.13 ft                               +0.11 ft
Kegonsa         843.21                   +0.41 ft                               +0.05 ft
 
We have received 0.75 inches of precipitation since April 1, 2011.  This compares to a normal of 1.51 inches.
 
As water levels on Lakes Monona and Waubesa have declined, we have increased flow out of Mendota 2 separate occasions.
 
Babcock County Park Lock and Dam remains completely open in full flow condition, since last April.
 
We have begun to decrease flow out of the Lafollette Lock and Dam in order to stay above the Summer Minimum on Lake Kegonsa.
 
The current strategy is to maintain the lake levels on the lower end of the summer 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.
