Martin Bay Boat Ramp on Lake McConaughy features two separate ramp sections with different end-of-ramp elevations (3,234. 0 feet for the south half and 3,244. 0 feet for the north half), allowing boaters to choose based on current lake levels.

The ramp is operational when Lake McConaughy's elevation exceeds the ramp end elevation by at least 3-4 feet to ensure safe launching.

Located on the north side of the lake between Martin Bay and Arthur Bay entrances, this access point serves both motorboats and paddlecraft users accessing Nebraska's largest reservoir.
