Ecologically, the park is diverse as a result of a variety of topographic and hydrologic features. The rolling hills of park uplands are dominated by mixed prairie communities of short- and midgrasses including sand dropseed, needle-and-thread, blue grams, western wheatgrass, little bluestem, and fortes such as blazing star, purple and white prairie clover, hairy golden aster, fringed sagewort, winterfat, yucca, and prickly-pear cactus. The reservoir shoreline and the South Platte River and Plum Creek floodplains support large wetland, riparian, and aquatic communities. Ponds and wetland habitats have also been created at the southwestern edge of the park through a cooperative venture with the neighboring Lockheed-Martin facility.
Chatfield State Park is situated in the lower foothills of the Front Range on the southwestern edge of Denver at an elevation of 5,450 feet. With a 1,400 surface-acre reservoir at the confluence of Plum Creek and the South Platte River and extraordinary views of the surrounding foothills, the park is one of the most popular recreation areas in the Denver metropolitan region. Chatfield occupies a gently rolling plain mantled with alluvial cobble, gravel, sand, silt, and clay with some exposures of older sandstones and shales.
