Jim Kreitlow, a DNR lakes biologist, said there was enough opposition to the plan for Keyes Lake that the agency will instead look for another lake for the project.
It would have been the first time the state used the pesticide in open water.
The plan called for the state and U.S. Geological Survey to apply Zequanox to the lake. 300 native clams, encrusted with zebra mussels would have been put in nine pens five feet below the surface. A barrier would have been placed around the pens, with a 12-hour dose Zequanox then mixed in. The pesticide kills zebra mussels but not other organisms.
