Moses Lake Municipal Airport is a public use airport located within the city of Moses Lake.[1] The airport property was deeded to the city in 1947 by the Northern Pacific Railroad. Since 1994, operations at the Municipal Airport have been overseen by the Airport Commission.[2] In February 2021, the wording of closure conditions for the airport was changed by the city to promote development.[3]
