June 10th Update

                                         Elevation        Change from 5/27/11     Summer Max
 
Mendota         849.90                  + 0.05 ft                               - 0.20 ft
Monona          845.12                   - 0.20 ft                               - 0.08 ft
Waubesa        844.78                    -0.07 ft                               - 0.22 ft
Kegonsa         843.28                    -0.02 ft                               - 0.22 ft
 
We have received 12.38 inches of precipitation since January 1, 2011.  This compares to a normal of 12.55 inches for the same time frame. 
 
As expected in the last update, Lake Monona has continued to decline.  As a result of the rain event this week, Lake Monona bounced up 0.09 ft.
 
As lakes are near  mid range of their respective water levels, we have been slowly stabilizing flow from one lake to the other.  We have decreased flow out of Mendota, Waubesa and Kegonsa as they are near their  respective mid range levels.  
 
Our weed scout has traveled the river between Lakes Waubesa and Kegonsa on Sunday June 5th and again on  Thursday June 9th.  Vegetative growth is primarily Wild Celery.  We had expected warm temperatures would have accelerated plant growth, but is not the case.  We will continue to monitor this section on a weekly basis. 
 
We have aquatic plant harvesters in Lake Monona, however vegetative density is not very high.
