WISCONSIN RESERVOIR LEVELS

April 21 2025
       

In Wisconsin, the latest observations indicate that several major reservoirs and dams are reporting gage heights below their average measurements for this time of year. Lake Winnebago at Oshkosh and near Stockbridge, Lac Vieux Desert near Land O'Lakes, Devils Lake near Baraboo, Lake Mendota at Madison, Lake Monona at Madison, and Lake Waubesa at McFarland are all experiencing lower water levels, with deviations ranging from 0.1 to 1.12 feet below average. This could be indicative of abnormal conditions affecting water storage and flow patterns in the state's water systems. These measurements, last observed on April 21, 2025, are critical for water management and could signal potential issues for ecosystems, agriculture, and water supply.

Cross-referencing with additional data sources such as news8000.com and countrymessenger.com reveals concerns over a dry winter possibly leading to a dry spring, which might explain the observed lower gage heights. The decreased snowpack from a drier winter may result in less springtime runoff into reservoirs. Lake Monona, for instance, shows a gage height 1.12 feet below its average—a significant drop that could be linked to these broader climatic trends. Such conditions not only affect water storage and recreational activities but also have implications for water quality and wildlife habitats. The current data suggests a need for close monitoring and potentially proactive water management strategies to mitigate the impacts of these deviations from normal reservoir levels as Wisconsin moves deeper into the spring season.
