Why would the City of Whitewater do a lake drawdown?

We are trying to freeze out and control invasive aquatic plants, including Starry Stonewort & Eurasian Milfoil. We currently perform a weed harvest twice a season to reduce the number of weeds in our lakes. An extended drawdown has many other benefits to the lake including sediment desiccation, which means the silty or mucky bottom can compress up to 1/3 of its depth when fully dried out. This would result in deeper water in our shallow shore areas. This along with a dry dredging while the lake is drawn down would allow for deeper lake and a navigable channel for recreational use. An extended drawdown also would also allow other invasive species to be controlled, while some beneficial native plants, that provide excellent fish and wildlife habitat, are expected to rebound. The extended drawdown would also give the city and/or DNR an ideal chance to inspect the dam while it’s dry.
