Fly Fishing the Missouri River, North Dakota: Sections, Seasons and Trip Plan
North Dakota's Missouri River runs cold below Garrison Dam, where Game and Fish stocks trout and the tailrace holds the state's brown and rainbow trout records. Downstream past Washburn and Bismarck to Lake Oahe, the same big, dam-controlled river turns into a boat-and-bank fishery for walleye, sauger, northern pike, smallmouth bass and catfish.
Now the honest part: the Fly Fishing Insider Podcast archive has no guest, episode or tip about the Missouri River in North Dakota yet, so the facts below come from North Dakota Game and Fish, the U.S. Army Corps of Engineers, USGS and state tourism sources, and every podcast tip on this page is labeled transferable.

Missouri River Section by Section
Garrison Dam was finished in 1953, nine years before Oahe Dam. The river between them, which Game and Fish calls the Garrison Reach, breaks into four pieces.
1. The Garrison Dam Tailrace (Riverdale and Pick City)
The powerhouse outlet directly below the dam. Access is from the East Tailrace Recreation Area (boat ramp, shoreline, fish cleaning station) and the Spillway Pond Recreation Area, both open year-round per North Dakota Tourism. Game and Fish has reported about 40,000 rainbow and brown trout stocked here a year, plus 11,420 tiger trout in spring 2026. Fish the riprap and wingwalls or run a boat. Full detail is on our Garrison Dam Tailrace page.
2. Downstream Recreation Area to Cross Ranch
The river braids south past Washburn to Cross Ranch State Park near Center, which North Dakota Tourism says sits on some of the last free-flowing and undeveloped stretches of the Missouri. The park has a boat ramp. This is float or boat water; Game and Fish expects the tiger trout to spread south, holding in deeper holes and seams where fast and slow water meet.
3. Washburn to Bismarck-Mandan
Game and Fish found 97 to 98 percent of the river's paddlefish in a 10- to 12-mile reach above Bismarck, so May brings heavy boat traffic. In Bismarck, General Sibley Park has a ramp for boats under 15 feet, canoes and kayaks. Game and Fish reports good smallmouth numbers near Bismarck and abundant, underused channel catfish through the reach.
4. Below Bismarck to Lake Oahe
South of Bismarck the river slows into Lake Oahe. Game and Fish's 2026 report says small walleye are abundant but slow growing, with trophy potential remaining.
Reading the Missouri River Flows
Live USGS gauge: Missouri River at Bismarck (06342500). Daily dam releases: Corps Missouri River Basin Water Management. The Corps reported Garrison releasing 16,000 cfs in March 2026; in July 2026 the North Dakota Department of Water Resources put the river near 18,000 cfs against a normal 25,000, about two feet low, with plenty of visible sandbars.
Our reading: outside the tailrace shoreline and a few gravel bars, this is not wading water. At low releases, expect sandbars and shallow ramps and fish the deeper outside bends; when releases climb, fish push tight to banks, riprap and eddies.

Missouri River Rules to Know
- Closed areas: areas near the Garrison Dam Tailrace posted by the U.S. Army Corps of Engineers are closed to fishing (Game and Fish 2026-28).
- Bridges and wing-walls: any fish released from bridges and wing-walls, such as at the tailrace, must go into a fish basket or open container immediately (Game and Fish 2026-28).
- Bow and spear: closed on the Missouri River from Garrison Dam downstream three miles to the southern boundary of the Corps Downstream Recreational Area (Game and Fish 2026-28).
- Paddlefish and sturgeon: paddlefish and pallid, shovelnose and lake sturgeon taken on hook and line must be released immediately (Game and Fish 2026-28).
Plan a 3-Day Missouri River Trip
Day 1: Shore
The Garrison Dam Tailrace
Base in Riverdale or Pick City. Swing a white streamer on a sink tip from the East Tailrace shoreline at first light, then nymph the slower riprap edges.
Day 2: Float or boat
Cross Ranch Reach
Launch at Cross Ranch State Park and work braided channels and seams for walleye, pike and tiger trout. Base in Washburn or camp at the park.
Day 3: Boat or kayak
Bismarck Smallmouth Water
Launch a small boat or kayak at General Sibley Park and strip Clousers along rocky banks for smallmouth.
What to bring: a 9-foot 7- or 8-weight with sink tips, a 6-weight for smallmouth, heavy fluorocarbon bite tippet for pike, a PFD and a North Dakota fishing license.

Missouri River Fly Fishing Questions, Answered
Is there trout fishing on the Missouri River in North Dakota?
Yes. The Missouri River in the Garrison Dam Tailrace produced North Dakota's state records for brown trout (31 pounds, 11 ounces, 2005) and rainbow trout (21 pounds, 4 ounces, 1998), and Game and Fish says the tailrace still produces trophy fish of both. Tiger trout were added in 2026.
Should you wade or float the Missouri River in North Dakota?
Float or run a boat on most of North Dakota's Missouri River; it is wide, braided and controlled by Garrison Dam releases. Wading is realistic only along the tailrace riprap and on gravel bars at low flows. Check the USGS Bismarck gauge and the Corps daily release first.
When is the best time to fly fish the Missouri River in North Dakota?
Spring (March through May) and fall (September through October) are the best windows on North Dakota's Missouri River. Game and Fish calls the upper river a spring and fall walleye and sauger fishery, Chinook salmon gather near Garrison Dam in fall, and the tailrace stays open all winter. Summer is best for smallmouth and catfish.
Missouri River or Lake Sakakawea: which should a fly angler fish?
Pick the Missouri River below Garrison Dam for cold-water trout, fall salmon in current and river smallmouth. Pick Lake Sakakawea for shoreline smallmouth and northern pike in shallow bays. The two meet at Garrison Dam, so one trip can cover both.
