What to expect at Lake Sharpe Tailrace

Lake Sharpe Tailrace is the stretch of the Missouri River immediately below Oahe Dam, roughly 15 miles north of Pierre. The dam creates a cold-water discharge that makes this section distinct from the main lake above it — the water temperature stays cooler year-round, which changes which fish live here and when they bite. Walleye, northern pike, and channel catfish are the primary species, and the tailrace holds fish in predictable locations because the current and depth are consistent.

Access is straightforward: a public boat ramp sits at the Oahe Dam Visitor Center parking area on the west bank, and a second ramp is available downstream at the Sharpe Campground. Both are free. The tailrace itself is roughly 8 miles long before it widens into the main lake, and most productive fishing happens within the first 2 to 3 miles below the dam where current is strongest.

Key Takeaways

  • Walleye fishing is best in spring (April through May) and fall (September through October) when water temperatures match their preferred range, and night fishing with live bait or jigs produces most consistently.
  • Northern pike are present year-round but most active in spring and early summer; they respond to larger lures and live baitfish near structure and current breaks.
  • Channel catfish bite throughout summer and into fall, especially at night, and are the most forgiving species for anglers new to the tailrace.
  • Current speed varies with dam discharge, which changes daily; call the Oahe Dam office before fishing to learn what discharge rate is scheduled, as this affects where fish hold and how they feed.
  • South Dakota fishing licenses are required; a one-day license costs less than a full-season license if you are visiting from out of state.

Walleye fishing in spring and fall

Walleye are the most sought species in the tailrace, and they follow a predictable seasonal pattern. Spring (late April through May) is the strongest bite, when water temperatures climb from the low 40s into the 50s. Fish stage in deeper holes and along the current seams where fast water meets slower water — these edges are where walleye wait to intercept food without fighting the full force of the current.

Live bait is the most reliable approach: shiners or small perch fished on a slip sinker rig, cast uptream and allowed to drift with the current, will catch walleye consistently. Jigs tipped with live minnows work equally well and give you better control in heavy current. Fish at dawn, dusk, and throughout the night; walleye are light-sensitive and feed most actively when the sun is low or absent.

Fall (September through October) produces a second strong bite as water cools back into the 50s and 60s. The same techniques work, though fish may be slightly deeper and more concentrated in the main channel. Winter fishing is possible but requires patience — water temperatures drop into the 30s and 40s, walleye metabolism slows, and bites become infrequent.

Northern pike and summer fishing

Northern pike are present year-round but most aggressive in spring and early summer (April through June) when they are feeding heavily after spawning. Pike in the tailrace tend to be smaller than lake pike — 18 to 28 inches is typical — but they are numerous and willing to strike.

Pike respond to larger lures: 4- to 6-inch crankbaits, spoons, and soft plastics in bright colors (chartreuse, orange, white) work well. Cast near structure — fallen trees, rock piles, and the edges of current breaks — and retrieve with a steady pace or erratic motion to trigger strikes. Live baitfish (shiners or small perch) also work, especially if you are targeting larger pike. Early morning and late evening are most productive, though pike will bite throughout the day in spring.

Summer pike fishing (July and August) slows as water warms and pike move to deeper, cooler water. If you are fishing in summer, focus on the deepest holes in the tailrace and fish early and late in the day when surface temperatures are lowest.

Channel catfish through summer and fall

Channel catfish are the most reliable summer target and require the least technical approach. They bite throughout June, July, August, and into September, and they are far more forgiving of imperfect technique than walleye or pike. Catfish feed primarily at night, so plan to fish from sunset through midnight or later.

Use simple live bait: shiners, perch, or cut baitfish (shad or herring) on a basic slip sinker rig. Cast uptream and let the current carry your bait downcurrent, or fish stationary in deeper holes where catfish congregate. A 3/0 to 5/0 hook is standard. Catfish are not picky about presentation — they hunt by smell and taste, not sight — so focus on getting bait into the right depth rather than perfecting your cast.

Catfish in the tailrace range from 15 to 40 pounds, with most fish in the 18 to 25-pound range. A medium-power rod and 12- to 17-pound line is adequate. Bring a headlamp and plan to stay until at least midnight; the bite often improves as the night deepens.

Understanding dam discharge and water conditions

The Oahe Dam controls water flow into the tailrace, and discharge rates change daily based on power generation and water management needs. High discharge means faster current, which pushes fish into specific holding areas and makes fishing more difficult. Low discharge means slower current and more spread-out fish, but also less oxygenated water.

Call the Oahe Dam office at (605) 224-5862 before you fish to learn the scheduled discharge rate for the day. Ask specifically what the flow rate will be during your fishing window. High discharge (above 15,000 cubic feet per second) concentrates fish in deep holes and slack-water areas; low discharge (below 10,000 cubic feet per second) allows fish to spread throughout the tailrace. This single piece of information will change where you fish and how you approach the water.

Water temperature also varies seasonally. The dam draws water from deep in Lake Oahe, so tailrace water is consistently cooler than the main lake — typically 10 to 15 degrees colder. This keeps the tailrace fishable during summer heat and makes spring and fall the prime seasons when water temperatures are in the range where walleye and pike feed most actively.

Access, regulations, and what to bring

Two public boat ramps serve the tailrace. The Oahe Dam Visitor Center ramp (on the west bank, directly below the dam) is the primary access and has parking, restrooms, and a small visitor center. Sharpe Campground, located downstream, offers a second ramp and overnight camping if you want to fish multiple days. Both ramps are free.

A South Dakota fishing license is required. Non-residents can purchase a one-day license for a lower cost than a full-season license; licenses are available online through the South Dakota Game, Fish and Parks website or at most bait shops in Pierre. No special permit is needed for the tailrace itself.

Bring a 16- to 20-foot boat or larger if possible — the current is strong and the tailrace can be rough in wind. A smaller boat works but requires more skill to hold position. Bring extra anchors or a drift sock to hold position in current. Life jackets are required by law. Bring a headlamp if you plan to fish at night, and bring more bait than you think you will need — the current moves bait quickly and you may go through several containers in a session.

Seasonal timing and best times to fish

Spring (April and May) is the strongest season overall. Walleye bite heavily, pike are aggressive, and water temperatures are ideal for all species. Expect moderate crowds on weekends.

Summer (June through August) is productive for catfish and pike early in the season, but walleye fishing slows as water warms. July and August are the slowest months for walleye but remain good for catfish at night.

Fall (September and October) produces a second strong walleye bite and remains good for catfish. Water temperatures cool back into the range where walleye feed actively, and the tailrace becomes productive again after the summer lull.

Winter (November through March) is fishable but slow. Water temperatures drop into the 30s and 40s, fish metabolism slows, and bites become infrequent. Ice fishing is not practical on the tailrace because the current prevents ice formation in most areas.

Frequently Asked Questions

What size boat do I need to fish the tailrace safely?

A 16- to 20-foot boat with adequate power is ideal because the current is strong and the water can be rough in wind. Smaller boats (14 feet) can work if you are experienced with current and have good anchoring equipment, but you will spend more time fighting position than fishing. A drift sock or sea anchor helps hold position in current if your boat is underpowered.

Can I wade or fish from shore at Lake Sharpe Tailrace?

Wading is not safe because the current is strong and the bottom is uneven. Shore fishing is possible from the Oahe Dam Visitor Center area and from Sharpe Campground, but you will reach only the shallow margins. Most productive fishing requires a boat to access deeper water and current seams where fish hold.

What is the best time of day to fish the tailrace?

For walleye and pike, dawn and dusk are most productive, and night fishing (especially for walleye) often outproduces daytime. For catfish, night fishing (sunset through midnight or later) is standard. Daytime fishing is slowest overall, though pike will bite throughout the day in spring.

Do I need special tackle for the strong current?

Medium to medium-heavy rods (6 to 7 feet) with 12- to 17-pound line are standard. Heavier line helps you hold bottom in current and gives you better control of larger fish. Use slip sinkers rather than fixed weights so bait can drift naturally. Jigs (1/4 to 1/2 ounce) work well because they stay near bottom without snagging as easily as fixed weights.

What should I do if the dam discharge is very high when I arrive?

High discharge concentrates fish in deep holes and slack-water areas behind current breaks. Fish the deepest holes in the tailrace and look for areas where the main current splits around structure. You may catch fewer fish overall, but the fish that are biting will be concentrated. If discharge is extremely high (above 20,000 cubic feet per second), consider postponing your trip — safety becomes a concern and fishing becomes very difficult.
