In 1883, John Miles leased 3,000,000 acres (12,000 km2) of Cheyenne and Arapaho land to seven cattlemen. However, arguments soon developed between the cattlemen and the tribesmen. In 1885, the Federal government terminated all of the leases and ordered the cattlemen to remove their stock.[3]
The area was settled in 1886, whenJohn Seger established a colony along Cobb Creek. Seger convinced 120 Cheyenne and Arapaho to settle near the old ranch headquarters at Cobb Creek. The intent was that "Seger's Colony" would teach these tribes how to farm, using modern agricultural methods.[3] The name, Seger's Colony, would be shortened and become the present day town ofColony, Oklahoma.[5]
After the government declared the excess lands of theCheyenne and Arapaho Indian Reservation available for non-Indian settlement, the Cheyenne-Arapaho Opening was made available to homesteading on April 19, 1892, in theLand Run of 1892.[3] At that time, the town of Tacola, soon renamed toCloud Chief, was designated by the Secretary of the Interior as the county seat.[3]
Washita County is located in that part of western Oklahoma which was included in County H of theTerritory of Oklahoma, an organized incorporated territory of the United States that existed from May 2, 1890, until November 16, 1907, when it was joined with theIndian territory and admitted to the Union as the State of Oklahoma.[3] The county itself was renamed for theWashita River. The French had called the river "Faux Ouachita", literally meaning "false Washita", to distinguish it from the ‘true’ Ouachita in Arkansas and Louisiana. The spelling of the name of the Oklahoma Washita was changed by substituting "w" for "ou".[6]
An election in 1900 designated the town ofCordell as the county seat. It was favored by the majority because it was located in the center of the county. The election result was contested in court. The Oklahoma Territorial Supreme Court ruled in 1904 that the seat could not be moved without Federal authorization. The U. S. Congress moved the seat to Cordell in 1906. When the Oklahoma Constitution went into effect at statehood in 1907, it confirmed Cordell (by then relocated and renamed New Cordell) as the county seat.[3]
In 1948, the nation's first flood control dam under the authorization of theFlood Control Act of 1944 was completed in the Cloud Creek Watershed in Washita County.[7]
