Overview: Ottawa County sits in the northeastern corner of the state of Oklahoma. It is a region where Midwestern and Ozark influences meet. As reported in the 2000 U.S. census, the county had a population of 33,194. The county seat is Miami, a small city with historic downtown buildings and Route 66 connections.
Geography and communities
Ottawa County occupies a mixture of rolling hills and river valleys typical of the Ozark foothills. It borders both Kansas and Missouri, placing it within a tri-state cultural and economic area. Major communities include Miami, and smaller towns and townships that grew around mining and agriculture.
History and development
The county takes its name from the Ottawa (Odawa) people. Euro-American settlement increased in the late 19th and early 20th centuries, driven largely by lead and zinc mining as part of the Tri-State mining district. The mining boom shaped towns, rail lines and the local economy.
Economy, culture and landmarks
Mining, agriculture and light manufacturing have been economic mainstays. Miami and nearby towns developed tourist interest because historic U.S. Route 66 passes through the area; visitors seek preserved theaters, neon signs and small museums celebrating the road’s heritage. The county also hosts tribal offices and cultural institutions tied to the Ottawa Tribe and other Indigenous nations; see local resources for cultural programs.
Environmental legacy and modern issues
A notable chapter in Ottawa County’s recent history is the environmental impact of past mining. Portions of the county were part of the Tar Creek Superfund cleanup area; legacy contamination led to federal and state remediation efforts and, in some places, community relocations. Contemporary planning balances redevelopment, environmental restoration and preserving historic character.
