ePic-I called the number on your post and talked to Dennis at Pueblo State Parks. He said its OK to use a belly boat but not any other type of flotation devise-no kayaks, no hand carried boats, no pontoon boats, nada. I asked why no kayaks (thats what I have) and he really didn't have an answer-just said it is belly boats only. He did say the rules allowing different types of flotation devises may change in the future to allow more types. Oh well.
