Turtle Lake Muni sits in Turtle Lake, North Dakota. Field elevation is 1,916 ft MSL. The airport has one runway. Runway 08/26 is 3,148 ft long with a turf surface. There is no control tower. CTAF and UNICOM are both 122.8. No ILS approaches are published here.

Pattern altitude is not published. Use the standard 1,000 ft AGL pattern for light piston aircraft unless the current FAA Chart Supplement or the airport operator says otherwise. The airport remarks matter here. Runway 08/26 is soft when wet. Low intensity runway lights on 08/26 are out of service indefinitely. Deer and wildlife are reported on and near the field. There is also a 10 ft dropoff 50 ft beyond the threshold on Runway 08. Obstacles are close enough to matter. Runway 08 has 33 ft trees 740 ft from the threshold on centerline. Runway 26 has a 17 ft road 530 ft from the threshold on centerline.

There are no on-field FBOs listed. Plan ahead for your own fuel and service needs. For winter use, confirm conditions with the airport manager before you go. If you need clearance delivery, the published contact is Minneapolis ARTCC. This is a small non-towered field with turf, wildlife and winter surface concerns. Treat it like a short-field planning airport.
