The lakes were actually strip mined for coal in the 40's and stocked with fish in the 50's... Many of the lakes are 40-80' deep....
The big lake is 121 acres with an average depth of 46'. It's a lot of water....about 5500 acre feet.... Crystal clear water that grows trout really good!! The theme for big lake is based off of the California fisheries pumping out fat bass- lots of trout stockings and trophy bass mgmt..
The goal is to be the only midwest fishery pumping out double digit bass fairly consistently...
