Lake Elmo State Park, State park with 64-acre reservoir in Billings, United States

Lake Elmo State Park is a 123-acre public recreation area on the northeast side of Billings, Montana, at an elevation of 3,199 feet. Its 64-acre reservoir, fed by the Billings Bench Water Association Canal, has three beach-front areas, a fishing pier, two group-use shelters, a playground, and a fenced dog park on the west side.

The park was established in 1983 by Montana Fish, Wildlife & Parks to provide recreation opportunities for the Billings area. The project grew from a desire to create a public outdoor space where residents could pursue different leisure activities.

The reservoir is fed by the Billings Bench Water Association Canal, and the park's three beach-front areas, two group-use shelters and playground draw families from across Billings. A fenced dog park sits on the lake's west side, separate from the swimming beaches.

The park sits on the northeast side of Billings at 3,199 feet (975 m) elevation, with three beach-front areas, two group-use shelters and a fishing pier. The fenced dog park is on the lake's west side. Swimming and boating are limited to non-motorized craft on the 64-acre reservoir, fed by the Billings Bench Water Association Canal.

The park features a specialized Action Trackchair, an all-terrain vehicle for people with mobility limitations. This equipment allows visitors with disabilities to fully explore the trails and fishing areas on site.
