Getting a slip on Folsom (Browns Ravine)

I'm moving to El Dorado Hills in a couple of weeks and if my boat doesn't fit in my garage, I'm going to have to store it.

Any suggestions. I would prefer to store my boat in my Garage during the off season and in a slip on the water during the summer. What's the best way to get a slip at Brown's Ravine?

Thanks,
John
