What it’s like
The place. Mattawa is a small city in the dry Columbia Basin of central Washington, and it is a young one: residents are far younger than in most American towns, and most households rent their homes rather than own them. Incomes run below the county's, and more people live below the poverty line than is typical. Few adults hold a four-year degree. Winters are cold, with January days just above freezing and nights below it, while summers are hot and dry, and little rain or snow falls across the year.
Work. Many residents work in schools, hospitals and social care, and many more in farming, with manufacturing and shops also employing local people. Across Grant County, the largest workplaces include Columbia Farm Services, which runs apple orchards, the Moses Lake School District and Grant County PUD, which generates hydroelectric power. Unemployment in the county is slightly higher than a year ago, and the county has fewer jobs than it did the year before. The typical commute is a moderate one, and only a small share of people work from home.
Things to do. Wanapum Lake and Priest Rapids Lake, both reservoirs, are a short drive away and are the closest places for time on the water. Farther afield, Hanford Reach National Monument is a protected stretch of the river and its surrounding shrub-steppe, and Ginkgo Petrified Forest State Park is a protected area that takes a longer drive to reach.

FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms in Mattawa’s census tracts, against the rest of the country; all of them together, relatively moderate. It is meant for planning, not a substitute for a local risk assessment or a flood map: FEMA’s index.
From the U.S. Census Bureau’s 2020 census and its American Community Survey (2020–2024 five-year estimates), and the Bureau of Labor Statistics. A survey, so each figure has a margin of error, and figures it is not sure of are left out. More on Grant County and the Moses Lake, WA metro.
