The Lake Mendota gauge was providing incorrect readings earlier this month.  The gauge was corrected by USGS and previous readings have been updated with correct data.
The National Weather Service at the Dane County Regional Airport reported a total of 1.52 inches of precipitation since September 1.   We have received 21.82 inches of precipitation since January 1, 2011.  This is 5.48 inches below normal.  Last year, we received 32.97 inches of precipitation for the same time period.
All 4 lakes are now near their mid range.  We have stabilized flow and will maintain current levels pending any additional precipitation.  "Summer Operating Orders" continue till November 1.
