About Mill Bay Casino
Mill Bay Casino sits at 455 Wapato Lake Road in Manson, Washington, a lakeside community on the north shore of Lake Chelan. The property opened in 2004 and is operated by the Twelve Bands of the Confederated Tribes of the Colville Reservation under compact with the Washington State Gambling Commission. The 24/7 floor runs 620 gaming machines, 14 table games, a 3-table poker room, and a small nightclub. The minimum gambling age is 18.
Mill Bay is the lakeside sister to 12 Tribes Resort Casino, the Colville Tribes’ resort property in Omak. Where 12 Tribes is built as an overnight resort with hotel and spa, Mill Bay is a destination-day casino that benefits from Lake Chelan’s summer tourism economy. For broader context, see our Washington tribal casinos directory and the surrounding Manson listings.

Lake Chelan's resort-town casino
Mill Bay Casino is the right pick for vacationers in Manson or Chelan who want a real gaming floor without driving the Cascades. The 24/7 floor, 14-table pit, and 3-table poker room cover most needs, and the lakeside location is unique among Washington tribal venues. The trade-off is the absence of an attached hotel, which keeps Mill Bay a day or evening stop rather than an overnight base. For overnight stays, the sister Colville property in Omak is the call.

A break from the lake
Stayed at a Manson rental for a week and ducked into Mill Bay a couple of nights. Surprisingly busy floor for the size of the town. Pai Gow runs reliably and the poker room had 1/3 No Limit going on a Saturday. No hotel on site, but with our rental that didn't matter. Valet was a small luxury we didn't expect.
