Ottawa County is located in the northeastern corner of Oklahoma, bordering both Kansas and Missouri. As of the 2010 census, the population was 31,848.[1] Its county seat is Miami. It was named for the Ottawa Tribe of Oklahoma.[2] After the 2010 United States Census, Ottawa county became part of the Joplin, Missouri metropolitan area.


Archaeological studies indicate this area was inhabited by prehistoric people. According to the Encyclopedia of Oklahoma History & Culture, at the start of the 20th Century, there were eight Archaic sites (6000 B. C. to 1 A. D.), sixteen Woodland sites (1 A. D. to 1000 A.D.) and six Plains Village sites (1000 to 1500 A. D.).[2]

The Osage Nation had moved into the area by the 19th Century.They ceded this land to the Federal Government in exchange for another area farther west in Indian Territory. In 1828, the Western Cherokees ceded their land in Western Arkansas to the Federal Government and obtained the land just vacated by the Osage. In 1831, the Federal Government reacquired part of what would eventually become Ottawa County to resettle some smaller tribes, These included two tribes of Seneca, Shawnee, Quapaw, Peoria, Kaskaskias, Miami, Ottawa and Wyandotte. The Neosho Agency administered the affairs of these tribes from 1837 until 1871. In that year, it became the Quapaw Agency, serving only the tribes in Indian Territory.[2]


According to the U.S. Census Bureau, the county has a total area of 1,255 km² (485 mi²), of which 1,221 km² (471 mi²) is land and 35 km² (13 mi²) (2.77%) is water.[3] The eastern part of the county lies in the Ozark Plains, while the western is in the Neosho Lowlands.[2]

Lead and zinc mining has been important to the county economy since 1890. By 1910, the local mining industry had been controlled by a few large corporations, including Commerce Mining and Royalty Company, the Eagle-Picher Company, the Childers Mining Company, the LaClede Lead and Zinc Company, and the American Lead and Zinc Company. In 1926, at the region's peak of production, Ottawa County was the largest source of lead and zinc in the world. By the 1960s most of the mines had closed, leaving mine shafts, sinkholes, chat piles, and other dangers for future cleanup. Tripoli, primarily used as an abrasive, was found near Peoria in 1912, and continued to be mined into the twenty-first century.[2]
