St Michael, ND – The Spirit Lake Tribe is a federally recognized tribe established in 1867 and based on a reservation located in east-central North Dakota on the southern shores of Devils Lake. It is made up of people of the Sisseton and Wahpeton bands.  Since the late 20th century, the tribe has operated gaming facilities on its reservation to generate revenues for the welfare of its people.
Recent renovations to the Spirit Lake property enlarged the non-smoking section of the casino floor forcing smokers into smaller quarters.  Working with the facilities department, Casino Air engineered a smoke & odor remediation system to destroy the smoke and odor at the source and contain it from entering the non-smoking section of the casino floor.  Clean Air is good business.
