System Information

System Description

Neoga leases Lake Mattoon water from the City of Mattoon. The Reliant Energy peaker plant also withdraws water from the lake. Neoga has one intake on the lake that can transport water directly to the treatment plant at 255 gpm. During droughts, Lake Mattoon water is allocated to Mattoon and Neoga based on population ratios.
