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.

Trolling Motor FAQ
Basic bow-mount installation typically ranges from $250 to $500 in labor. For complex Smart Rigging (including NMEA 2000 networking, lithium battery trays, and on-board chargers), labor costs generally fall between $800 and $1,500.
Brushless motors (like the Minn Kota QUEST series) are significantly quieter, more powerful, and 30-50% more energy-efficient than traditional brushed motors. For Midwest anglers who regularly spend an entire day or more on the water, the upgrade pays for itself in extended battery life and the stealth on pressured fish in clear water.
90% of vibrations are caused by a bent prop pin or a chipped propeller. Even a tiny “tick” in the prop can cause massive vibration at high speeds. If the prop is clear, you likely have a bent armature or water intrusion in the lower unit, which requires immediate professional service to prevent total motor failure.
Yes. Many boaters are swapping three 12V lead-acid batteries for a single 24V or 36V LiFePO4 battery. This saves up to 150 lbs of weight, improves hole shot, and simplifies your charging setup. Just ensure your battery’s BMS (Battery Management System) can handle the motor’s peak amp draw.
Always use a stabilizer bracket (like the RAM or Minn Kota models) to lock the motor head in place. The constant bouncing on highways (or high waves) can cause the mounting bracket to crack or the motor to accidentally deploy, which can be catastrophic at 70 mph.
