Lake Francis Case is a 102,000-acre Missouri River reservoir in Gregory, Lyman, and Brule counties in south-central South Dakota — the second largest of the four Missouri River mainstem reservoirs in South Dakota and a premier walleye, smallmouth bass, and pike fishery drawing anglers from across the northern Great Plains. The lake stretches approximately 107 miles from Fort Randall Dam at the southern end to Big Bend Dam at the northern end, creating an expansive Missouri River impoundment with 540 miles of shoreline across the rolling prairie and river breaks of south-central South Dakota. The Missouri River walleye fishery on Lake Francis Case is nationally recognized — the lake produces trophy walleye in numbers that draw dedicated walleye anglers from across South Dakota, Nebraska, and Iowa specifically targeting the Francis Case corridor during the spring spawn and fall feeding periods. Smallmouth bass, northern pike, channel catfish, and white bass round out the year-round fishery. The communities of Chamberlain and Oacoma on either side of I-90 at the Missouri River crossing anchor the primary boating infrastructure and service market for the lake.

Monthly rates vary by protection level: Outdoor un-covered typically runs $50–$150; Outdoor covered/canopy is $150–$300; and Indoor heated storage generally ranges from $400 to $800+ depending on the boat’s length. For premium indoor winter packages near high-demand areas like Minneapolis, Milwaukee, and Chicago, expect to pay by the linear foot.

Most fire marshals and storage facilities require your tank to be either 95% full (to prevent condensation) or nearly empty (less than 5 gallons) for safety. Regardless of the level, always use a high-quality fuel stabilizer to prevent ethanol phase-separation during the long Midwest winter.
Most standard policies cover the hull while in a lay-up period, but you must notify your agent if you are moving it to a professional facility. Some facilities require you to provide a Certificate of Insurance naming them as additionally insured before they will accept the vessel.
Dry-stacking is ideal for boaters who want the protection of indoor storage without the hassle of a trailer. Your boat is stored in a giant rack system and “valeted” into the water by a heavy-duty forklift whenever you’re ready to ride. This is a very popular option for large cruisers on the Great Lakes.
