MICHIGAN RESERVOIR REPORT

Last Updated: March 3, 2026

Michigan's dams and reservoirs are experiencing a mix of conditions as of the latest data observed on March 3, 2026. Lake Gogebic near Bergland is experiencing significantly lower water levels with a gage height of 1 ft, compared to its average of 2.33 ft. This could be a cause for concern given that it reflects a substantial deviation from normal conditions. Conversely, Greenwood Reservoir near Greenwood is slightly above its average gage height of 113.13 ft, standing at 114 ft. Most other reservoirs, such as Cisco Lake near Watersmeet and Austin Lake near Kalamazoo, are maintaining near-average levels. However, Stony Lake near Washington displays a notable decrease, with its current gage height at 6 ft, substantially lower than the average of 10.93 ft. The causes for these deviations may be attributed to a variety of factors, including recent weather patterns and environmental incidents.

Given recent reports, environmental and weather conditions may be playing a significant role in the observed data. Michigan recently cited a trucking firm for spilling microplastics into a river, which could impact water quality and possibly storage levels as clean-up efforts proceed. Moreover, weather patterns have been extreme; with reports of intense cold and cloudy skies in Michigan, the reduced snowpack could be contributing to lower inflows into the reservoirs. Additionally, early March has seen severe storms ranging from Texas to Michigan, increasing the risk of flooding and subsequently affecting dam operations and water levels. For instance, the reduced level at Lake Gogebic could be tied to lower snowpack melting, whereas the slightly elevated level at Greenwood Reservoir might be the result of recent storm activity. It is crucial to continue monitoring these conditions, as abnormal gage heights could indicate potential issues in water management and supply, as well as influence local ecosystems and communities.

Michigan has over 1200 dams, 200 of which are major dams, many of which form significant reservoirs. The state's major reservoirs include Lake St. Clair, Houghton Lake, Higgins Lake, Hubbard Lake, Manistee Lake, and Hamlin Lake. These reservoirs are primarily fed by various rivers, including the St. Clair River, Au Sable River, and Manistee River. Michigan's hydrology is heavily influenced by snowpack and winter precipitation, which provide the bulk of the water supply for the state's streams and reservoirs. The Upper Peninsula, with its higher elevations and colder temperatures, typically has higher snowpack levels and more significant snowmelt runoff than the Lower Peninsula. Some areas of the state have experienced record high water levels and flooding in recent years, while other areas have experienced drought conditions. Seasonal trends in water levels vary by location and depend on factors such as snowmelt timing and precipitation patterns. Overall, Michigan's reservoirs and dams play a crucial role in regulating water supply and managing flood risk in the state.
