What it’s like
The place. Deep River is a very small Iowa city, one of the smallest places a person could choose to live. Nearly everyone owns the home they live in, and fewer households live below the poverty line than is common nationally. Few adults hold a four-year degree, and the typical drive to work is a long one.
Work. Residents work mostly in schools, hospitals and social care, with manufacturing, shops and the building trades close behind. Across Poweshiek County, the largest workplaces include Grinnell College, Grinnell Mutual Reinsurance Co and Grinnell Regional Medical Center. Jobs across the county have dipped from the year before, and unemployment there is a little lower than it was a year ago.
Things to do. Winters are cold, with January highs near freezing, and summers are warm; a good deal of rain and melted snow falls across the year. For time outdoors, Pilot Grove State Preserve is a protected area a longer drive away, as are Rock Creek State Park and Lake Keomah State Park. The Skunk River, also a longer drive away, suits an afternoon by the water.

FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms in Deep River’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 Poweshiek County.
