The state Department of Natural Resources warns boaters to watch out for debris on the Wisconsin River left by last month's floods. The DNR says most of the debris washed downstream from the Lake Delton area and remains in the river between there and Portage. Regional warden supervisor Barbara Wolf says the agency has documented more than 80 visible piles, some as large as a roof section that was part of a house that washed away when Lake Delton drained into the river. Some of the debris is just under the water, posing a risk to boaters, waterskiers and personal watercrafts, she says. State, federal and county officials are discussing how to get rid of the debris.
