There is boat rentals available at Hume Lake Christian Camps at 64144 Hume Lake Rd. (I'm not sure if they open during the winter time.) It's right across from the gas station, US post office and the gift shop.
My husband, my kids (7&11) and I rented a row boat and had a blast!! The boat rental runs only for $15/hour (as of summer 2012. --$20 minimum charge for a "motor" boat rental) -- No membership necessary. The park pass, a photo ID and a $50 deposit w/credit card were required when we signed on the waver. The life jackets and a pair of oars were provided up on check-in.
The staff there were nice and friendly.
We were on the boat for about an hour and it was so relaxing and refreshing. The mountain view from the lake was spectacular! Bring your hats and a plenty of sun screen lotion as there is no shade on the boat :)
*Note - The boat house closes on Sundays between 10:15am and 1:45pm --probably for the staff to attend Sunday services. They will be back to the office at 1:45pm.
