Grand Casino Mille Lacs
Onamia, Minnesota
Onamia is on the southern shore of Mille Lacs Lake — Minnesota’s second-largest lake at approximately 132,516 acres — in Mille Lacs County. Mille Lacs Lake is one of Minnesota’s premier walleye fishing destinations, drawing ice fishers and open-water anglers year-round. The Mille Lacs Band holds treaty-protected fishing rights on Mille Lacs Lake reaffirmed by the U.S. Supreme Court in 1999 — a landmark tribal sovereignty ruling. Grand Casino Mille Lacs serves both the local Onamia community and the substantial lake recreation visitor market.
