Lake Francis Case begins with the tailwaters of Big Bend and flows southward more than 100 miles, between the Crow Creek and Lower Brule Indian reservations, past Chamberlain and onto Fort Randall Dam. Of all the sights and attractions, one of the most interesting is the dam itself, which is named after the 1860s-era Fort Randall. A visitor’s center has exhibits and even summer tours (pending COVID policies). Just west of the dam lie the remains of the old yellow chalkstone Fort Randall chapel, and a mile further is the post cemetery with a sign that records how the soldiers died.
