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

Illinois Drought


System Information

System Description

Blandinsville obtains its water supply from La Harpe Creek and uses two off-channel reservoirs, North Res. and South Res., for storage. Water is withdrawn from an intake adjacent to North Reservoir using a pump that is typically operated at 300 gpm. This pump may also be used to transfer water to South Reservoir, which is adjacent to the treatment plant.

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

Developments since 1989:

A new off-channel reservoir for additional storage was constructed in 1992. The community did not implement any mandatory conservation measures during the 2005 drought, but it often could pump only 7-8 hours per day during this period.

Note: *The School Property well is no longer online due to poor water quality. Withdrawals from Little Creek ceased after 1988 due to low flow problems.
