Lake Francis Case, SD fishing report
Lake Francis Case, formed by Fort Randall Dam on the Missouri River, is a walleye fishery at heart, with smallmouth bass offering a strong secondary bite that most visiting anglers underestimate. Walleye action peaks in early spring as fish stage near rocky points and wind-blown shorelines before and after the spawn, then again in fall when cooling water pushes them shallow to feed aggressively. Smallmouth thrive around the lake's abundant riprap, rocky bluffs, and boulder-strewn flats, with their best action running from late spring through early fall.
For walleye, slow-trolling live crawlers on bottom bouncers along sloping rock transitions is a proven producer, especially when surface temps drop into the mid-50s or below. Target depth breaks where current-influenced areas meet calmer water near the dam tailwaters or main-lake points. Smallmouth respond well to tube jigs and drop-shots worked tight to submerged rock structure. Pay attention to wind direction — sustained northwest winds concentrate baitfish and predators alike on the windward shores, and that's often where both species stack up.
