Patagonia Lake State Park offers two cement boat ramps that can accommodate most size boats during normal water levels, with day-use or camping permits covering launch fees at no additional cost.

Both motorized and non-motorized watercraft are permitted, though personal watercraft and jet skis are prohibited, and the lake features designated no-wake and unlimited-speed zones.

The marina on-site provides boat rentals including canoes, rowboats, paddle boats, and pontoon boats, making it accessible for visitors without their own watercraft.
