What it’s like

The place. Cambridge is a very small city in Washington County, Idaho, the sort of place where residents are likely to know one another by name. Winters are cold, with January the coldest month and daytime highs staying close to freezing, while summers turn properly hot in July. Rain and melted snow add up to a fairly dry year overall.

Work. Many residents work in schools, hospitals and social care, and others in manufacturing, the building trades, or farming, forestry and mining. Across Washington County, the largest workplaces include Champion Home Builders, the Weiser District schools and Memorial Hospital. Household incomes in the county run a little below the national picture, and the county has lost a small share of its jobs over the past year.

Things to do. Several rivers lie within reach, including the Weiser River and the Powder River, though each is a longer drive away. Lake Cascade, a large reservoir, is also a longer drive, as is Tamarack Resort, a ski area for the colder months.

FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms in Cambridge’s census tracts, against the rest of the country; all of them together, relatively high. 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 Washington County.
