There are campgrounds it just isn't assigned camp sites etc.... Just more first come first serve but they are labeled like campground A B C ( I think they are labeled with just letters as the Tige reunion last year was the only time I have been there). They have bathrooms as well but if you have a camper I would steer clear of the bathrooms. We were in site C I believe.
Boat ramps there SUCK SUCK SUCK!!!!!!!!!!!!!!!!!!!! You back in and it seems deep enough then it gets shallow again. So you need to launch with one person in the boat so the damn thing will float off the trailer. Then take the boat over near the beach and make your crew swim out. Or take a big azz crew and have them all shove the boat off trailer minus the girls who stay in the boat.
There are no boat rangers. NONE. While we were there, there was one truck ranger that drove around for about 30 minutes in the morning and 30 minutes in the evening. There are no marinas and gas is way back at the highway. So if you can't make it the weekend on a tank of gas take fuel cans with you or be prepared to drive 30 minutes back to the interstate to fill up.
The water was glass basically the entire time we were there except when the famous Wyoming wind kicks up. We left our boat in the water all weekend and just swam out to it from the beach. If you have a really good anchor I suggest this because once again the boat ramps SUCK!!!!!! Also if it has rained anytime recently do not try and launch or retrieve from the beach. If you do attempt this you may end up like our buddy Big George.
