The Oklahoma-based Quapaw Tribe’s USD 200 million Downstream Casino Resort is set to open July 5 on the Kansas state line about seven miles west of Joplin. A 12-story, 226-room hotel will be the tallest structure for miles around and is scheduled to open in the late fall. The first of 2,000 slot machines have arrived and are being installed. The casino won’t have craps or roulette, but it will offer blackjack and other table games, mini-baccarat, a poker room and a race book.
