Left Tailrace

Left Tailrace Recreation Area is a U.S. Army Corps of Engineers facility located on the shore of Lake Sharpe along the Missouri River below Big Bend Dam in central South Dakota. Situated three miles from the town of Fort Thompson, 20 miles from Chamberlain, and 65 miles from Pierre, the state capital, Left Tailrace provides access to some of South Dakota's most productive fishing waters. The campground occupies the left bank of the Missouri River immediately downstream of Big Bend Dam, where water releases create ideal conditions for game fish. The recreation area is part of the larger Big Bend Dam and Lake Sharpe complex, which was constructed by the Corps of Engineers as part of the Pick-Sloan Missouri Basin Program. Left Tailrace serves as a primary destination for anglers pursuing walleye and other game species, while also offering camping, boating, and other outdoor recreation opportunities in the heart of Missouri River country.

The tailrace waters below Big Bend Dam support exceptional fisheries for walleye, the primary game species, along with sauger, smallmouth bass, white bass, channel catfish, and northern pike. The churning waters released through the dam's turbines concentrate fish and baitfish, creating productive fishing conditions year-round. The Missouri River corridor provides critical habitat along major bird migratory routes, with geese, ducks, pelicans, and other waterfowl commonly observed in the skies and on the water. Bald eagles frequent the tailrace area, particularly during winter months when open water below the dam attracts both eagles and their prey fish. The surrounding riparian zones support white-tailed and mule deer, while the grasslands beyond host ring-necked pheasants, sharp-tailed grouse, cottontail rabbits, and coyotes. Beaver activity is evident along quieter stretches of the river, and various songbirds inhabit the cottonwood galleries lining the banks.

The vegetation surrounding Left Tailrace reflects the transition between the mixed-grass prairie uplands and the riparian corridor of the Missouri River. Mature eastern cottonwood trees dominate the riverbank forests, interspersed with green ash, American elm, and box elder in the floodplain areas. The understory includes chokecherry, buffaloberry, and wild plum shrubs that provide food and cover for wildlife. Native prairie grasses including little bluestem, blue grama, and western wheatgrass cover the upland areas beyond the riparian zone. Invasive species management presents ongoing challenges, with Russian olive and saltcedar occasionally encroaching on native plant communities. Aquatic vegetation in the tailrace waters and along quieter shorelines provides habitat for fish and invertebrates. Seasonal wildflowers including purple coneflower, black-eyed Susan, and various sunflower species bloom throughout the summer months in the prairie areas surrounding the campground.

The geology of the Left Tailrace area is dominated by the Missouri River valley and the materials exposed by its cutting through the northern Great Plains. Big Bend Dam is constructed across a reach where the Missouri carved its channel through shale bedrock at the edge of the Pleistocene glacial zone. The famous Big Bend of the Missouri, located upstream, represents one of the most dramatic river meanders in North America, with a 22-mile circumference around a neck only 1.6 miles wide. Indurated shale cliffs in the crook of the upstream bend have resisted erosion, maintaining this unusual river feature. The Pierre Shale formation, a Cretaceous-age marine deposit, underlies much of the region. Lake Sharpe, the reservoir behind Big Bend Dam, covers approximately 56,884 acres and drains a watershed of nearly 250,000 square miles. The tailrace area features coarse gravels and cobbles deposited by the river before dam construction.

Left Tailrace Recreation Area experiences a semi-arid continental climate characteristic of central South Dakota. Summers are warm with average high temperatures in the mid-80s to low 90s Fahrenheit, while winters bring cold conditions with average lows near zero degrees. Annual precipitation averages approximately 18 to 20 inches, with most moisture falling as thunderstorms during the spring and summer months. The Missouri River creates a moderating influence on local temperatures, keeping the tailrace area slightly warmer in winter and cooler in summer than surrounding uplands. Wind is a persistent factor, with prevailing northwesterly winds in winter and southerly winds in summer. Severe thunderstorms producing large hail, damaging winds, and occasional tornadoes are possible from May through August. Winter ice fishing in the tailrace area is possible when temperatures permit, though the flowing water below the dam often remains at least partially open.

The Left Tailrace area lies within lands traditionally occupied by the Crow Creek Sioux and Lower Brule Sioux tribes, whose ancestors inhabited the Missouri River valley for centuries. The Lewis and Clark Expedition passed through this region in 1804, documenting the landscape and interactions with indigenous peoples. The construction of Big Bend Dam in the 1960s represented a transformative event for the region, as authorized by the Flood Control Act of 1944 as part of the Pick-Sloan Plan for Missouri River watershed development. Dam construction began in 1959 with embankment completion in July 1963 and power generation beginning in 1964. The project resulted in significant impacts on the Crow Creek and Lower Brule reservations, including the displacement of families and the flooding of traditional lands, garden plots, and resources used for food and medicine. The tailrace recreation area was developed to provide public access to the productive fishing waters created by the dam.

Left Tailrace Recreation Area was established by the U.S. Army Corps of Engineers as part of the Big Bend Dam project recreational facilities. Following the dam's completion in 1966, the Corps developed camping and day-use facilities to accommodate visitors attracted by the exceptional fishing opportunities in the tailrace waters. The campground has evolved over subsequent decades, with facility improvements including the addition of electrical hookups at campsites, modern comfort stations with showers, a dump station, and enhanced boat launching facilities. A fish cleaning station was added to serve the many successful anglers who visit the area. Recreation amenities have expanded to include a disc golf course, playground equipment, horseshoe pits, and bean bag toss areas. The recreation area is now managed as part of the Corps's Lake Sharpe recreational facilities, with reservations available through Recreation.gov. Ongoing improvements continue to enhance the visitor experience while maintaining access to the prime fishing waters.

The primary attraction of Left Tailrace Recreation Area is the exceptional fishing in the waters immediately below Big Bend Dam. Walleye fishing draws anglers from across the region, with sauger, smallmouth bass, white bass, channel catfish, and northern pike also providing quality fishing action. A well-maintained boat ramp provides access to the river, while a courtesy dock facilitates launching and retrieval. Bank fishing opportunities exist along the tailrace shoreline. The fish cleaning station allows anglers to process their catch on-site. Beyond fishing, the recreation area offers a nine-hole disc golf course winding through the campground area. Playground equipment provides family-friendly recreation, while horseshoe pits and bean bag toss areas offer additional activities. The proximity to the Big Bend of the Missouri provides opportunities for scenic exploration of this remarkable geological feature. Wildlife watching, particularly for bald eagles during winter months, attracts visitors interested in natural history.

Left Tailrace Campground offers 81 campsites with electrical hookups and 12 non-electrical tent sites. Electrical sites feature 30 and 50 amp pedestals with paved pull-through and back-in configurations. Modern comfort stations provide restrooms with flush toilets and showers. A dump station serves RV campers, and drinking water is available throughout the campground. Day-use facilities include picnic shelters with tables and grills. The boat ramp, courtesy dock, and fish cleaning station serve anglers accessing the tailrace waters. Left Tailrace is located three miles from Fort Thompson on Highway 47, with Chamberlain approximately 20 miles distant providing full commercial services including fuel, groceries, and lodging. Pierre, the state capital, lies 65 miles north. Reservations can be made through Recreation.gov or by calling 1-877-444-6777. The recreation area operates seasonally, with some facilities closed during winter months.

Left Tailrace Recreation Area operates within the framework of the U.S. Army Corps of Engineers' environmental stewardship responsibilities for the Missouri River mainstem reservoir system. Fish populations in the tailrace waters are managed cooperatively with the South Dakota Department of Game, Fish, and Parks, with regulations designed to ensure sustainable harvest of walleye and other game species. The Corps monitors water quality in the tailrace and downstream reaches. Efforts to protect and enhance riparian habitat along the Missouri River corridor benefit wildlife populations and water quality. The impacts of dam construction on the Crow Creek and Lower Brule Sioux reservations remain a significant historical consideration, with ongoing relationships between the Corps and tribal governments addressing resource management issues. Invasive species monitoring programs track threats including Asian carp and zebra mussels. The recreation area practices Leave No Trace principles and maintains recycling facilities to minimize environmental impacts from camping activities.
