Live water for the Mount Rushmore State — the great Missouri reservoirs Oahe, Sharpe & Francis Case, the Black Hills lakes, and the glacial walleye lakes of the northeast. This is walleye country, with cold-water trout in the Black Hills. The dammed reservoirs with NWPS gauges run live; the ungauged glacial lakes & Lewis & Clark read as honest SNAPSHOT cards. Every tube shows the pool, the current level, the lake's two signature fish (hover for the species, click for 2026 tournaments), and a live bite gauge. Scroll down for the Black Hills trout streams, the Missouri channel cats, the paddle rivers, and the Prairie Pothole duck country.

The Black Hills hold the only wild trout in the Dakotas — brown & rainbow in Rapid Creek below Pactola, Spearfish Creek in its canyon, and Whitewood Creek. The cylinder shows live gage height (ft) — low = wadeable, high = fast, off-color water. Hover a trout for the species; tap it for a guide.
Roughly 100–200 cfs is prime wadeable/tubing flow; big releases above ~1,000 cfs run fast and cold. Always check Canyon Dam releases before wading.
The Missouri below Oahe (Pierre) and below Gavins Point (Yankton) gives up trophy flathead & channel cats, along with the James & the Big Sioux at Sioux Falls. Live river stage (ft) from NOAA, with action & flood marked. Rising, off-color water turns the cats on. Hover a cat; tap it for a guide.
The Missouri National Recreational River below Gavins Point is the last free-flowing stretch of the river; the Big Sioux, James & Belle Fourche run the prairie & the Hills. Live USGS gage height (ft); each tube marks FLOAT, EXPERT & FLOOD. Hover a fish; tap it for an outfitter.
The Missouri below Gavins Point is dam-controlled and floatable most of the season; the Black Hills & prairie rivers are flashier. Always check the gage before launching.
Northeast South Dakota sits in the heart of the Prairie Pothole Region — Sand Lake & Waubay NWRs and the glacial lakes pull migrating ducks down the James & Missouri flyways. Live water-level (ft) from NOAA & USGS. Hover a duck for the species; tap it for a guide.
The potholes & refuges fill with snowmelt & rain for the fall migration. Duck season runs roughly late September–December.
