John Martin Reservoir State Park

John Martin Reservoir extends across 2,500 water acres and 5,000 land acres, providing space for water activities and land-based recreation throughout the year.

The reservoir originated in the 1940s through the damming of the Arkansas River, fundamentally changing water management and agricultural practices in southeastern Colorado.

Native American tribes frequented this land before European settlement, leaving archaeological evidence of their presence near the current reservoir grounds.

The park maintains 213 camping sites with electrical and non-electrical options, multiple boat ramps, swimming areas, and extensive hiking trails for visitors.

Winter brings thousands of migrating waterfowl to the reservoir, creating one of Colorado's largest winter waterfowl populations.
