The trick here is that you are boating in fresh water on the Great Salt Lake flood plain, separated from the salt by an earth-filled dike about 20 miles long. That structure has an official name, the Arthur V. Watkins Dam, though almost nobody uses it. There are two separate marinas, north and south, with separate entrances, so decide which side you want before you turn off. The campgrounds sit under cottonwoods, which matters on an exposed shoreline at 4,200 feet.
