What to do
Wildlife viewing along shorelines: During low water levels, particularly in late summer, diverse bird species create an impressive soundscape. "The bird sounds are incredible. I wish I would have made a recording. Mourning doves, quail, robins, and red wing blackbirds among the many" notes a visitor to Potholes State Park Campground.

Tips from RVers
Site selection strategies: Consider sun exposure when choosing spots. "We got site 98 which backs up to the lake. Great idea, but due to people having no manners, we had people walking through our campsite to get to the water to fish constantly," advises an RV camper at Potholes State Park.
Hookup availability: Utility options vary between loops. "The 60-site RV section offers full hookups with power, water, and sewer connections," while "The RV sites have power, water, and sewer. They are arranged like a wheel, you drive around the small center and the other trailers are the spokes in the wheel."
Food storage practices: Wildlife can access unsecured items. "This trip, there were racoons that liked our food more than we did. First night, we lost a half gallon glass jar of dog food. It had a lid on it, and it took me until the second night to figure it out," warns a camper about their experience at Potholes State Park.
