I fished Rice lake last year by accident. I'm a dumb-ass and thought I was launching on Whitewater Lake. I don't think I brought any fish home out of this lake, but I didn't fish it very long. Once I realized I was on the wrong lake I pulled out and went to Whitewater. You should have no problem launching your boat there. They've got a very nice landing and parking area. Much less fishing pressure than Whitewater Lake as well, so fewer boats to contend with.
I have not really fished this lake in a few years. And then it was Ice Fishing. Rice Lake gets very green from the algae in the water. Not sure why when the water coming out of Whitewater Lake is fairly clear. The pan fish are fairly small. I have caught one nice bass a few years back.
