Biologist believe hot, dry weather has created the best conditions for renovating this fish population because the drought has dried up many upstream pools that may have harbored undesirable fish species. After the lake is drained, the existing water in the lake basin will be treated with rotenone, a fish toxicant. Because Kingman is an ANS-designated water due to white perch, fish salvage will not be allowed, reducing the risk of white perch transfer into non-infested waters.
Dewatering of the lake will begin in mid-August. During renovation, a number of lake improvement projects will take place, including fish habitat placement, boat ramp extension, and chemical treatment of problematic shoreline vegetation. Upon refilling of the lake, largemouth bass, northern pike, bluegill, and channel catfish will be restocked.
“Hopefully, fall rains and increased spring flow will fill the lake by spring of 2013,” says Sean T. Lynott, Kansas Department of Wildlife, Parks and Tourism’s regional fisheries supervisor for southern Kansas. “After the renovation, the lake will not be closed to fishing because some adult fish will be stocked immediately to prey on any undesirable fish not eliminated by the chemical treatment. Additionally, the newly-stocked fish should grow quickly without competition from rough fish, so fishing should quickly improve in the years to come.”
