The Department of Natural Resources says an experiment to help clear upClear Lake has shown an immediate impact. D-N-R biologist Jim Wahlsays the bottom-feeding fish were killed in Ventura Marsh last week. Themarsh is adjacent to Clear Lake and Wahl says those fish churned up sedimentthat flowed from the marsh into the lake.The water in Ventura Marsh is now twice as clear as before the fish kill. Wahl says they hope a clearer marsh will lead to more plants growing on themarsh bottom. The plants will help clean out other contaminants that couldget into the lake.Wahl says the fish kill method has been used in lakes, but never before in ashallow marsh. The fish kill is the first step, keeping the fish out of themarsh is the next step.Wahl says they will also introduce predator fish into the marsh to keep anyleft over bottom-feeders from flourishing again. Cleaning up Ventura Marshis part of larger effort to reduce the contaminants and algae in Clear Lake.
