SAUK/PRAIRIE (91C) sits in Prairie du Sac, Wisconsin. The field elevation is 832 ft MSL. It has one runway, 18/36, which is 2,936 ft long and asphalt. There is no control tower. Pattern altitude is not published, so light piston traffic should use the standard 1,000 ft AGL unless the current Chart Supplement says otherwise. No ILS approaches are published here.
Blue Sky Flight is on the field. It carries 100LL and UL94. Twenty-four hour self-serve fuel is available with credit card. That helps for after-hours arrivals. Still verify current access with the FBO directly before you go.
This is a non-towered field with Madison Approach/Departure handling clearances when needed. When Madison Approach is closed, clearance delivery goes through Chicago ARTCC. Keep an eye out for maintenance vehicles and ultralight activity in the area. West ramp and taxiway are private and closed to transient aircraft. There is also a hospital and helipad about 3,000 ft southeast of the runway 36 threshold, so plan your pattern and departure path with that in mind. Runway 18 departures should climb to 1,800 ft MSL on runway heading before turning east or southeast. Runway lighting, REILs and PAPI are all controlled by CTAF.
