OTTERTAIL LAKE
THREE FORKS, MT
Ottertail Lake is MT36, a publicly owned, non-towered airport serving Three Forks, Montana. Its single runway, 08/26, is a turf and dirt strip 1,852 feet long and 30 feet wide.
Operations are restricted to visual flight rules, as no instrument approach procedures are published. The non-towered field has no published frequencies, so pilots keep their own separation using standard see-and-avoid procedures. No fuel service is available. As a private-use facility, the airport does not accommodate transient traffic without prior permission from the owner.
The field sits at 4,155 feet above mean sea level. At that elevation, density altitude is a routine consideration in warm weather.
