American Falls Reservoir, formed by the dam on the Snake River, covers much of the county&#8217;s northern edge and is the county&#8217;s dominant water feature. The county borders <a href=\"https:\/\/townsvillages.com\/us\/bannock-county\/\">Bannock County<\/a> to the east, <a href=\"https:\/\/townsvillages.com\/us\/blaine-county\/\">Blaine County<\/a> to the north, <a href=\"https:\/\/townsvillages.com\/us\/cassia-county\/\">Cassia County<\/a> to the southwest, <a href=\"https:\/\/townsvillages.com\/us\/bingham-county\/\">Bingham County<\/a> to the north, and Oneida County to the south.<\/p>\n<h2>Demographics<\/h2>\n<p>Power County had 7,878 residents at the 2020 census. American Falls and Rockland are the two largest communities; most of the rest of the population lives on farms and ranches outside any incorporated place. The county&#8217;s median household income runs well below the Idaho median of $74,942, reflecting its largely agricultural economy. Population density is roughly 5.6 people per square mile.<\/p>\n<h2>Economy &amp; Local Life<\/h2>\n<p>Agriculture drives the county economy &mdash; irrigated potato, wheat, and alfalfa farming along the Snake River bottomlands, and cattle ranching on the Arbon Valley range. The American Falls Dam and its reservoir support both irrigation and hydroelectric generation, the industry the county was named for. American Falls serves as the county&#8217;s retail and government center.<\/p>\n<h2>History<\/h2>\n<p>The Idaho Legislature created Power County on January 30, 1913, by partitioning it from Cassia County. The name comes from an early hydroelectric power plant built at American Falls on the Snake River in 1902. American Falls itself has a notable history: it is the first town in the United States to be entirely relocated, moved uphill in 1925 so the original townsite could be flooded by the newly dammed reservoir.<\/p>\n<h2>Getting There<\/h2>\n<p>Interstate 86 and U.S. Route 30 cross the county, linking American Falls to Pocatello and the wider Snake River plain.<\/p>\n<ul>\n<li>Pocatello &mdash; 25 miles east<\/li>\n<li>Twin Falls &mdash; 55 miles southwest<\/li>\n<li>Idaho Falls &mdash; 45 miles northeast<\/li>\n<li>Boise &mdash; 165 miles west<\/li>\n<\/ul>\n<p>The nearest commercial airport is Pocatello Regional Airport.<\/p>\n<h2>Frequently Asked Questions<\/h2>\n<p><strong>Where is Power County?<\/strong><br \/>It is in southeastern Idaho, on the Snake River plain southwest of Pocatello.<\/p>\n<p><strong>What is the population of Power County?<\/strong><br \/>7,878 people, at the 2020 census.<\/p>\n<p><strong>How big is Power County?<\/strong><br \/>1,443 square miles (3,738 km2).<\/p>\n<p><strong>What is the county seat of Power County?<\/strong><br \/>American Falls.<\/p>\n<p><strong>How many towns are in Power County?<\/strong><br \/>Two incorporated municipalities, American Falls and Rockland, plus about a dozen unincorporated communities.<\/p>\n<p><strong>What ZIP codes are in Power County?<\/strong><br \/>83211 (American Falls) and 83271 (Rockland).<\/p>\n<p><strong>Why is it called Power County?<\/strong><br \/>For an early hydroelectric power plant built at American Falls on the Snake River in 1902.<\/p>\n<p>More counties in this state: <a href=\"https:\/\/townsvillages.com\/us\/category\/idaho\/\">Towns and villages in Idaho<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Power County is a county in Idaho, United States, on the Snake River plain southwest of Pocatello.
