Neosho residents. Neosho lies on the western edge of the Ozarks.The name "Neosho" is generally accepted to be of Native American derivation, meaning "clear, cold water", referring to local freshwater springs. The springs attracted varying cultures of Native American inhabitants for thousands of years. It was also ideal for the later white settlers, who founded the city in 1833. It was incorporated as a municipal government in 1878. Nicknamed "City of Springs", Neosho has long served as an agricultural center and, since 1888, is home of the Neosho National Fish Hatchery, the oldest in the National Fish Hatchery System. It is known locally as the "Gateway to the Ozarks", and since 1957 as "the Flower Box City".
