The Iowa Department of Natural Resources is considering the removal of fish from Ventura Marsh to help get rid of some of the water quality problems at Clear Lake. D-N-R spokesman Bill Jinkinson says they are considering a plan that would eliminate what are called “rough fish” from the marsh on the west end of the lake. He says the fish — which are mostly carp — stir up sediment on the bottom of the marsh and that keeps plants from growing. Without those plants more nutrients flow from the marsh into Clear Lake causing algae to grow. The algae clouds the lake and Jinkinson says removing the fish will cut back on algae growth and help clear the water. Removal ofthe fish is one of several plans the D-N-R is studying to clean up the lake.
