We have received 0.19 inches of precipitation in the form of snowfall since December 22nd .
Total precipitation received during the 2010 calendar year was 37.86 inches. Normal precipitation is 32.95 inches. Precipitation for 2009 was 38.35 inches.
Snow fall from December 1, 2010 to date, is 21.8 inches compared to the norm of 15.5 inches. We had a snow pack of 8 inches for the previous report, a trace remains today.
Currently Lake Mendota is 0.32 ft above Winter Minimum. Flow out of Lake Mendota was decreased in order to allow Lakes Monona and Waubesa to drop. We expect to maintain this flow rate for the next several weeks.
Locks and dams at both Babcock County Park and Lafollette County Park remain completely open since April, in full flow condition.
The operator of the Stoughton Dam is within their operating water level orders. Today's discharge is 355 cfs compared to a median average of 282 cfs. This increased flow assists in moving water volume out of the upper lakes.
