You can rent both electric and gas motors to fish on the lake: greatparks.org/parks/miami-whitewater-forest/miami-whitewater-forest-harbor There are not cabins at Miami Whitewater Forest; there are both deluxe and rustic cabin at Winton Woods campground: greatparks.org/parks/winton-woods/winton-woods-campground There is no swimming in Miami Whitewater Forest lake.
I know you can rent boats to fish with motors and paddles depending on what you want. Campgrounds, yes cabins not sure but wouldn't doubt it. 10 dollars for a year pass and the place is awesome. Haven't even seen the whole place yet. And your pass is good for all Hamilton county parks including Winton and Sharon woods. And a dozen more... Worth it!
