Let's try this again! Last time this season...pray for good weather!
The plan is to set off just above the dam, paddle upstream (it's EASY paddling) to the swimming hole, then float/paddle back. It should take 2-3 hours. Wear footware that stays on your feet when swimming. The river is deep so if you can't swim you should bring a life jacket. Dicks sporting goods has a tube for about $25 if you need one, but get one sooner rather than later...they don't stock many at one time.
