Of the county&#8217;s 1,474 square miles, 1,453 are land and 21 are water,<br \/>\nabout 1.4 percent, held mostly in reservoirs rather than natural lakes &mdash; Brownlee Reservoir<br \/>\non the Snake, plus Crane Creek, Mann Creek and Paddock Valley reservoirs. The Weiser River runs<br \/>\nthe length of the county from north to south before joining the Snake at the city of Weiser, and<br \/>\nthe Seven Devils foothills rise along the county&#8217;s eastern edge toward Adams County.<\/p>\n<p>Adams County borders Washington County to the north, Gem County to the east, Payette County to<br \/>\nthe south, and Malheur County, Oregon, lies across the Snake River to the west. <a\nhref=\"https:\/\/townsvillages.com\/us\/adams-county-idaho\/\">Adams County<\/a>, <a\nhref=\"https:\/\/townsvillages.com\/us\/gem-county\/\">Gem County<\/a>, <a\nhref=\"https:\/\/townsvillages.com\/us\/payette-county\/\">Payette County<\/a> and <a\nhref=\"https:\/\/townsvillages.com\/us\/malheur-county\/\">Malheur County<\/a> all border Washington<br \/>\ndirectly.<\/p>\n<h2>Demographics<\/h2>\n<p>Washington County had a population of 10,500 at the 2020 census, and a 2025 estimate puts the<br \/>\ncounty near 11,583 residents, a gain of roughly 10 percent. Weiser holds more than half the<br \/>\ncounty&#8217;s population outright, with Cambridge a distant second and Midvale third. Median<br \/>\nhousehold income runs about $54,000, below Idaho&#8217;s statewide 2023 ACS figure of $74,942.<br \/>\nPopulation density works out to roughly 7 people per square mile of land, low even by rural Idaho<br \/>\nstandards, and just over half the county&#8217;s residents live in Weiser&#8217;s urbanized area<br \/>\nwhile the rest are spread across the Weiser River valley and the surrounding ranch country.<\/p>\n<h2>Economy &amp; Local Life<\/h2>\n<p>Manufacturing is the county&#8217;s largest employment sector, with about 485 workers, followed<br \/>\nby educational services at 467 and construction at 445. Weiser Memorial Hospital and the local<br \/>\nschool district are among the county&#8217;s biggest single employers, and farm, orchard and<br \/>\nlivestock operations still anchor much of the rural economy along the Weiser and Snake river<br \/>\nbottoms. The county&#8217;s best-known annual event is the National Oldtime Fiddlers&#8217;<br \/>\nContest, held in Weiser during the third full week of June every year since 1953; it draws more<br \/>\nthan 7,000 visitors and has earned the city its nickname, the Fiddling Capital of the World.<\/p>\n<h2>History<\/h2>\n<p>Idaho&#8217;s territorial legislature created Washington County on 20 February 1879, naming it<br \/>\nfor President George Washington. Weiser, at the confluence of the Weiser and Snake rivers, became<br \/>\nthe county seat as the area&#8217;s farm and orchard economy grew around the rail line. Cambridge<br \/>\ntook shape after the Idaho Northern Railway reached the valley in 1901 and bypassed the older<br \/>\nsettlement of Salubria nearby, drawing most of Salubria&#8217;s businesses to the new depot town.<\/p>\n<p>Weiser also has a niche place in baseball history: Hall of Fame pitcher Walter Johnson played<br \/>\nsemi-pro ball for the Weiser Kids in 1906 and 1907, at age 19, before signing with the Washington<br \/>\nSenators and going on to a 21-season major league career.<\/p>\n<h2>Getting There<\/h2>\n<p>No interstate crosses Washington County. U.S. Route 95 runs the length of the county<br \/>\nnorth&ndash;south through Weiser, Cambridge and Midvale, and State Highway 71 branches northwest<br \/>\nfrom Cambridge toward Brownlee Dam on the Snake River.<\/p>\n<ul>\n<li>Boise &mdash; about 60 miles south<\/li>\n<li>Ontario, Oregon &mdash; about 20 miles west<\/li>\n<li>Payette &mdash; about 14 miles south<\/li>\n<li>McCall &mdash; about 88 miles north<\/li>\n<\/ul>\n<p>Boise Airport, roughly 60 miles south of Weiser, is the nearest scheduled commercial air<br \/>\nservice.
