La Harpe
System Information
System Description
Water pumped from Crooked Creek to the La Harpe off-channel reservoir at up to 500 gpm provides approximately 60 percent of the community's water. Water can be pumped from the reservoir to the surface water treatment plant at up to 160 gpm. A shallow well supplies the remaining 40 percent, all of which is treated at a separate plant.

Developments since 1989:
Crooked Creek went dry during the 2005 drought, but La Harpe's groundwater supply limited that impact to a bulk water sales ban. These withdrawals lowered the water table just 8 feet above the pump (70 feet below the surface), roughly 5 feet lower than the average annual minimum level. Boy Scouts have built another sedimentation basin for the lake.
