Located in southeastern Colorado's high desert prairie, John Martin Reservoir offers expansive paddling opportunities across its 12,286 acres. The reservoir provides uncrowded conditions for water activities, with two distinct paddling areas: the main reservoir and Lake Hasty.

The main reservoir allows all types of boating from March 15 through October 31, with boat ramps closing November 1 through March 14 for waterfowl resting. The east boat ramp, located on the northeast side past Sandstone Cove day-use area, provides the primary access point. Due to fluctuating water levels, paddlers should watch for floating debris, submerged hazards, and shallow areas that may not be marked.

Lake Hasty, situated below the dam, offers a quieter paddling experience limited to hand-launched, non-motorized vessels. This smaller lake provides an ideal environment for beginning paddlers or those seeking calmer waters.

Essential facilities include picnic areas at Point Overlook and Lake Hasty Recreation Areas, modern campgrounds, and restrooms. The 4.5-mile Red Shin Trail parallels portions of the water, offering paddlers opportunities to combine hiking with their water pursuits.

Wildlife viewing opportunities abound, with 373 documented bird species making the reservoir a premier birding destination. Paddlers may spot bald eagles (particularly numerous in winter), endangered least terns, and threatened piping plovers. The shoreline supports diverse wildlife including deer, coyotes, and prairie dogs.

The reservoir's historical significance stems from its location along the historic Santa Fe Trail, with preserved trail sections and markers visible along the north shore. The surrounding landscape features high rocky bluffs, shortgrass prairie, and notable plants including prickly pear cactus and yucca.

Park hours run from 5 a.m. to 10 p.m. daily, with a daily vehicle pass required ($10). All vessels must undergo inspection for aquatic nuisance species before launching. Certain shoreline areas may be temporarily closed to protect endangered bird nesting sites.
