"You're going to be in the water anyway," Des Moines County Conservation administrative assistant Jeff Breuer said Friday, but it looks like the rain will be gone long before the boats hit the water. Big Hollow's Fill the Lake Flotilla will be similar to Floatzilla, the Quad Cities' annual fleet of kayaks and canoes on the Mississippi every third Saturday in August.
