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

Illinois Drought


System Information

System Description

Two separate intakes on Shoal Creek convey water at up to 700 gpm each into two off-channel reservoirs that can exchange water via a valve, although only one pump is typically operated at a time. A 2.0 mgd treatment plant can receive water from either reservoir or directly from the downstream intake on Shoal Creek via gravity flow.
