Illinois Drought


System Information

System Description

Lake Lou Yaeger, the system's principal water source, conveys water to the 2.7 mgd treatment plant. During most years, water from Litchfield Lake is withdrawn when Lake Lou Yaeger is drawn down 4-5 feet in December to prevent ice damage to the lake's marina.
