Grand Lake O’ the Cherokees is a 46,500-acre reservoir on the Neosho River in northeastern Oklahoma — one of the largest lakes in Oklahoma and the premier recreational boating destination for the Tulsa metropolitan area’s eastern reach and the four-state corner region where Oklahoma, Kansas, Missouri, and Arkansas converge. The lake sits in Ottawa, Delaware, and Mayes counties in the Ozark foothills with 1,300 miles of shoreline that supports a large marina infrastructure, resort community, and year-round boating economy centered on Grove, Langley, and Afton. The Neosho River arm and the numerous creek tributaries across Grand Lake’s 1,300-mile shoreline produce exceptional largemouth and smallmouth bass, crappie, walleye, and catfish fishing that drives a major tournament fishing economy alongside the recreational boating and houseboat market. Grand Lake’s proximity to Tulsa — approximately 70 miles to the southwest — makes it the most heavily used large reservoir in northeastern Oklahoma and drives consistent marine service demand across the Grove and Langley corridor throughout the open water season.
