Wildlife Viewing

Bring your binoculars and camera. The Santa Fe Slough on the east and west sides of the Dam Road provides excellent opportunities to view waterfowl in their natural habitat. The west side of the dam also features a viewing blind.


Protecting Natural Habitat

The sand and gravel shores of John Martin Reservoir are among the few remaining nesting areas in the State of Colorado for the threatened Piping Plover and the endangered Interior Least Tern. Nesting areas may be fenced to protect them. Disturbing these shore birds or their nesting areas is a violation of State and Federal law. Under no circumstances enter the areas that are fenced off. Plover nests are very difficult to see, and it is quite possible that you could step on and crush plover eggs by mistake. For more information, stop by the Information Center or contact the Colorado Division of Wildlife (719.336.4852).
