Located five miles south of Kahlotus, Washington, Lower Monumental is one of three state-managed airports on the Snake River. WSDOT leases the airport from the Corps of Engineers. Camping is available on the airport. For dam tours, call 509-282-3219.

The 3,300 foot gravel runway is located part way up the west wall of the canyon. The airport elevation is 813 feet, and density altitude problems are common in the summer.  The surface is gravel and in good condition and has been compacted and oiled yearly since 2009.  A vehicle access gate has been installed to limit unauthorized airport access; however people and animals have been observed on the runway. Spray operators also occasionally use the facilities. Vehicle access is allowed by permission only on a limited basis by contacting the state airport manager.  

The windsock is located midfield on the west side. Terrain rises quickly east and south of the field. There is a powerline 2300 feet north of the airport, and another paralleling the field 500 feet west. We recommend overflight to determine field conditions and check for obstructions. Watch for snakes while walking around. The airport is open year round however in winters months if a rare snow occurs, its closed.
