Market Overview
Moses Lake, WA
Moses Lake is centrally located in Washington State’s Columbia Basin region. Nestled alongside its namesake, Moses Lake, this community has rapidly grown into a regional economic hub. The city's economy is diverse, with a strong presence in agriculture, manufacturing, and technology, including a major data center and two new electric vehicle manufacturing facilities.
Moses Lake's strategic location at the crossroads of major highways and railroads, plus its access to inexpensive power due to the Columbia River's dam systems makes it a pivotal transportation, logistics, and manufacturing center for the Pacific Northwest. In addition, the area's affordability relative to the remainder of the Inland Northwest is a draw for families, employees, and businesses alike.
