RWY 29

Garrison Dam Recreational Airpark sits in Riverdale, North Dakota. Field elevation is 1,723 ft MSL. The airport has one runway, 11/29, which is 3,195 ft long. It is a non-towered field. CTAF is 122.9. No ILS approaches are published here. Pattern altitude is not published, so use 1,000 ft AGL unless the current Chart Supplement says otherwise.

This is a turf-gravel runway with numerous small rocks on the surface. Runway 11 and 29 use nonstandard markings. Edges and thresholds are marked with black and white cones. The runway also has 400-foot dirt and gravel stopways at both ends. There is a 3-foot hill 500 feet from the runway end 100 feet right of the extended centerline at runway 11. There is also a 3-foot road 463 feet from the runway end on the extended centerline at runway 29. Runway 11 has a 30-foot drop off 450 feet from the threshold.

The airport is closed from October through May. Surfaces are soft when wet. No snow removal is available. That makes surface condition a real planning item here. For clearance delivery, contact Minneapolis ARTCC. Phone attendance is available Monday through Friday from 0800 to 1700. After hours, use the listed manager cell numbers. No on-field FBOs are listed, so verify services with the airport operator before you go.
