Reservoir report
Illinois has several reservoirs and dams, primarily used for flood control, municipal water supply, and recreational activities. Major reservoirs in the state include Lake Shelbyville, Lake Springfield, Lake Decatur, and Rend Lake. These reservoirs receive water from various streams and rivers, including the Kaskaskia River, Sangamon River, and the Little Wabash River. Snowpack and mountains are not significant factors in Illinois hydrology, as the state has a relatively flat landscape. However, seasonal trends can affect water levels, with higher precipitation in the spring and lower levels in the summer. Drought conditions can also impact reservoir levels, with Lake Shelbyville experiencing record low levels in 2012 due to a severe drought. Overall, Illinois' reservoirs and dams play a critical role in managing water resources for the state's population and economy.

Reservoir FAQ

About Illinois dams & reservoirs

Where does the Illinois dam data come from?

The U.S. Army Corps of Engineers National Inventory of Dams (NID) plus state water-resource agencies. Snoflo joins these public records with live USGS streamgauge readings downstream where available. The NID is the canonical federal dam registry.

What does Hazard Potential mean?

USACE classifies every dam by what would happen if it failed: Low (no loss of life expected, minimal economic damage), Significant (no loss of life but economic, environmental, or lifeline damage), High (loss of life expected). It's a downstream-consequence rating, not a likelihood of failure.

What is Normal Storage in acre-feet?

The volume of water the reservoir holds at its normal operating level, measured in acre-feet. One acre-foot is about 325,851 gallons or 1,233 cubic meters — the amount needed to cover one acre to a depth of one foot.

Why are some Illinois dams missing storage or height data?

USACE NID records can have gaps for small or older dams that pre-date federal reporting requirements. Snoflo surfaces whatever the canonical record contains. If a dam you care about has incomplete data, contact the operating agency or USACE for updates.

Can I see live water levels?

Yes — tap any dam name to open its detail page, which pulls live storage data from USGS streamgauges or operating-agency feeds where available. Historical levels and seasonal averages are also shown.

Why does Illinois have so many dams?

The U.S. has over 90,000 dams — most built between 1930 and 1980 during the federal water-development era. Illinois's count reflects a combination of agricultural irrigation needs, flood control, hydropower, and recreation. The "Built by decade" chart above shows the timeline.
