Developments since 1989:
A new 1.5 mgd treatment plant was constructed in 1999. An intake was constructed along Beaucoup Creek in 2002 to meet the demand of the new Ameren peaker plant and to protect the system against drought. This intake has been used only to fill the lake with a total of 26.5 million gallons during the 2005 drought.
Note: *Production has increased in recent years due to demands of the Ameren peaker plant.
