Drought Vulnerability of Illinois' Community Surface Water Systems, Illinois State Water Survey

Illinois Drought


System Information

System Description

The system receives water from both surface (Spring Lake) and groundwater sources. The wells have been in service since a reverse osmosis plant was constructed in 2004. During an emergency, two pumps at an intake on the La Moine River can pump water at up to 2500 gpm each.

1989 Study:

50-year drought yield sufficient at present level of water use.

USGS Gages:

No data available

Developments since 1989:

Groundwater production is expected to increase in coming years. This dependable water supply allowed the community to profit from bulk water sales during the dry 2006 summer. Western Illinois University conducted a sediment survey of Spring Lake in summer 2007 and is currently processing the results.
