March 18th lake level update

   Elevation               Change from March 4th, 2011              Summer Min

Mendota         849.07                   +0.19 ft                                - 0.53 ft
Monona          844.80                   +0.07 ft                                +0.10 ft
Waubesa         844.50                   +0.08 ft                                - 0.00 ft
Kegonsa         842.82                   +0.11 ft                                - 0.18 ft

We have received 0.53 inches of mixed precipitation since March 4th, 2011       .

Snow fall for the 2010/11 season, is 71.0 inches compared to the norm of 43.5 inches.  Snow pack has disappeared.  Only snow piles remain.

Frost is rapidly coming out of the ground. 

Locks and dams at both Babcock County Park and Lafollette County Park remain completely open since April, in full flow condition.

The Stoughton Dam is operating at mid range of their water level orders.  Discharge at the Fortun St location in Stoughton is 435 cfs compared to the long term median of 389 cfs.

National Weather Service is predicting precipitation Sunday and again this coming mid week.  We expect to maintain current flow rate for the next week to allow additional runoff to pass through the system. Pending accumulated precipitation and resulting water levels, we may reduce flow at either Kegonsa and or Tenney to slowly get those lakes to their respective Summer Minimum. 

The intent will be to remain at Summer Minimum for the short term.
