Grove is a city in Delaware County, Oklahoma, in the northeastern corner of the state, surrounded by Grand Lake o' the Cherokees, one of the region's most popular recreational reservoirs. With a population of 6,956 at the 2020 census, Grove functions as the primary commercial and service hub for the lake and its surrounding area, a role that defines both its economy and its character. The lake is the center of life in Grove. Grand Lake o' the Cherokees is a major destination for boating, fishing, and waterfront recreation, and it hosts professional bass fishing tournaments that draw anglers from across the country. During the spring, summer, and fall travel season, Grove's population swells as visitors, second-home owners, and lake enthusiasts arrive, animating the city's shops, restaurants, and marinas. Grove's history is intertwined with Grand Lake's development. The city grew slowly for much of its early history, but tourism and expansion came to dominate after 1950, when the lake's development made Grove a retirement and recreation destination. That role continues today, with the city serving both a permanent population and a much larger seasonal community drawn to the water. Public education is provided by Grove Public Schools, serving the city and surrounding area. The community also offers cultural and historical attractions, most notably Har-Ber Village, a pioneer-era history museum and open-air village with nearly 100 exhibits across several scenic acres. For residents, Grove offers a relaxed, lake-centered lifestyle in northeast Oklahoma, combining year-round small-city living with the energy and recreation of one of the region's most popular lakes.
