The water level of Lake Winnebago in Wisconsin is currently at 3.35 feet Oshkosh Datum, well above the typical early May target of 2.7 feet, and is expected to remain above 3.3 feet through the weekend and into next week.



This increased water level occurred rapidly over the past few days. The water level of Lake Winnebago on May 1 was 2.68 feet, slightly above the target operating band of our regulation strategy.
Heavy rain and runoff from snowmelt have caused increased inflow to Lake Winnebago.

Much of the Winnebago/Fox/Wolf basin has received two to four inches of rain since May 1, including three to four inches falling directly over the lake. Inflow rates have risen to 13,000 cubic feet per second, where the average inflow rate for early May is approximately 8,300 cfs.
