Lake Oahe is a 370,000-acre Missouri River reservoir stretching from Oahe Dam at Pierre, South Dakota north through the Standing Rock Sioux Reservation into south-central North Dakota — the largest reservoir in South Dakota by surface area and one of the most celebrated walleye fisheries in North America. The Mobridge corridor on the Standing Rock Sioux Reservation side of the lake sits near the geographic center of Oahe’s most productive walleye water — the expansive Missouri River impoundment produces walleye fishing that draws dedicated anglers from across the northern United States and Canada who specifically target the Mobridge reach for its trophy walleye potential. The lake stretches approximately 231 miles from Oahe Dam to the Bismarck North Dakota area, creating a massive reservoir across the rolling prairie of central South Dakota and south-central North Dakota with 2,250 miles of shoreline. Northern pike, smallmouth bass, chinook salmon, and channel catfish round out the year-round fishery.

Trailer Repair FAQ
A professional bearing repack typically costs $200 to $400 per axle. This includes disassembling the hub, cleaning the bearings, inspecting for wear, and “repacking” with high-quality marine-grade grease. If the bearings or races are pitted and require replacement, expect to add $50–$100 per wheel for parts.
It depends on your boat’s weight and which state lines you’re crossing. While many Midwest states (like Illinois and Michigan) require brakes at the 3,000 lbs GVWR mark, others like Ohio and Tennessee have lower thresholds. Because these laws vary significantly across our 16-state corridor and are subject to change in 2026, it is your responsibility to verify the current requirements for every state you plan to travel through.
Even if the tread looks deep, boat trailer tires (ST tires) should be replaced every 5 to 6 years. The combination of sitting in the sun (UV damage) and carrying heavy loads causes “dry rot” in the sidewalls, which leads to blowouts on the highway.
90% of trailer light issues are caused by a bad ground connection. Because boat trailers are submerged in water, the wiring harness and connectors are prone to corrosion. Upgrading to a “sealed” LED wiring harness is the best way to prevent the constant headache of non-functioning lights.
It depends on your boat type and where you launch. Bunk Trailers are best for fiberglass boats and heavy vessels. They offer superior hull support and a simple drive-on loading experience. They are cheaper to maintain but require deeper water to launch. Roller Trailers are ideal for shallow ramps or solo launching. They allow the boat to glide off easily even if the trailer is not fully submerged. However, they have more moving parts to maintain and can cause pressure points on some fiberglass hulls.
