Part of Johnson’s Shut-Ins State Park are open today and will stay open through September 3rd. Camping will not be allowed, but swimming will be allowed in the Shut-Ins area. The picnic grounds and the park store will be open. The rest of the park is still considered a construction area and is not open to the public. A breach in the dam holding back the Taum Sauk Reservoir near Lesterville December 14th, 2005 sent a billion gallons of water down the mountain and through the Johnson’s Shut-Ins State Park, seriously injuring the park superintendent’s family. AmerenUE, the owner of the reservoir, has delayed repair of the dam while it negotiates a settlement with the state of legal issues surrounding the collapse.
