Just got back from a fantastic weekend of walleye fishing on Francis Case Reservoir in South Dakota out of Chamberlain! I found most of the fish to be in shallow from 7 feet of water in towards the shoreline. Bottom bouncers and plain Lindy Rig snells tipped with a minnow was one of the tactics along with pitching 1/8 X-Change jigs tipped with a minnow to the rocks on the shoreline. Carpenter's bluffs south of town were pretty consistent along with the shallow willows/flats across from Carpenters. Nothing huge (limits of 15 to 18 inch walleyes and saugers) along with a bunch of smaller eyes/saugers, but tons of fun.
The scenery on this reservoir is just plain breath taking. Rolling hills and high bluffs are the norm. Excellent food and launch sites are easy to find in Chamberlain. For motel accomodations, make sure you check out the Oasis Inn.
