As early as 1901, fish and wildlife representatives noted that carp were causing the trout population in the lake to collapse. Due to their habit of grubbing through bottom sediments for food, carp stir up sediments and increase the turbidity of the water. In addition, they destroy submerged vegetation that holds sediments in place and provides shelter for native fish populations. Without vegetation, winds can more easily stir up sediment from the bottom of the lake, which is already a problem due to the lake's shallowness, resulting in greater turbidity and less sunlight reaching the remaining vegetation. Without cover for their young, native fish, such as the June sucker, become easy prey for white bass, walleye, and other predators.
