Cherry Creek is a tributary of the South Platte River, long, in Colorado in the United States.
Course
Cherry Creek rises in the high plateau, east of the Front Range, in northwestern El Paso County. It flows north, through Castlewood Canyon State Park where it is spanned by the historic Cherry Creek Bridge, past Parker and through portions of Centennial and Aurora, and into southeast Denver. It flows northwest through Denver, becoming an urban stream and joining the South Platte River at Confluence Park in central Denver just west of downtown and approximately east of the foothills, near the site where the city of Denver was founded in 1858.
The Cherry Creek Dam, completed in 1950, forms Cherry Creek Reservoir in Cherry Creek State Park, providing flood control and irrigation. The dam lies immediately southeast and southwest of the Denver and Aurora city limits, respectively, approximately from the creek's confluence with the South Platte.
The creek lends its name to the Cherry Creek neighborhood in south-central Denver, and also in particular to its Cherry Creek Shopping Center. In addition, the creek runs through the suburban Cherry Creek Public Schools district. The Cherry Creek Bike Path follows the creek from Confluence Park in downtown Denver through Cherry Creek State Park and south towards Parker and Castlewood Canyon.
History
Cherry Creek was the focus of the early part of the Pikes Peak Gold Rush in 1858 and 1859, when gold was discovered at the "Cherry Creek diggings," in what was then western Kansas Territory. The first edition of the Rocky Mountain News on 23 April 1859 identified itself on the masthead as being located at "Cherry Creek, K. T." Gold was discovered at Russellville (now in Douglas County) in the upper Cherry Creek drainage, and in the Platte River near its confluence with Cherry Creek.
Speer Boulevard, running along Cherry Creek, is part of Denver's parks and parkway system, and is listed on the National Register of Historic Places.
Castlewood Dam was constructed on Cherry Creek in 1890 to provide irrigation to surrounding farms in Douglas County. After decades of notoriously leaking, the dam suffered an utter collapse following heavy rains at 1 am on 3 August 1933, resulting in a 15-foot wall of water rushing down Cherry Creek to Denver, some 15 miles away. Warnings to the city by 4 am allowed most people to move out of the way of the flood waters. The dam's remnants are still visible at Castlewood Canyon State Park.
Ecology
The creek itself is locally well known for its population of crayfish. Some local inhabitants catch and eat these crustaceans. The creek is also home to a large population of small fish (Including immature trout and sunfish, crappie, yellow perch and others). Large fish are largely absent, except when the Cherry Creek Dam is partially opened and floodwaters carry fish such as rainbow trout, brown trout, mature sunfish, walleye, and even northern pike downstream. The creek's ecosystem was damaged during a drought in the first few years of the 21st century. Plants along the banks, damaged by the drought, dropped organic debris into the water, increasing biochemical oxygen demand substantially. Decreased flow also limited the ecosystem's capacity to supply needed oxygen. Decreased flow also prevented the washing away of pollutants such as NPK fertilizers, insecticides and organic solvents. Water temperatures also rose during this period, compounding the problem. As of 2005, however, the creek is substantially healthier.
The area around the creek is also known for its snake population, which includes garter snakes, western hognose snakes, bullsnakes and occasionally rattlesnakes. Amphibians native to Colorado can be found at the creek as well. These include, the plains leopard frog, woodhouse's frog, and the striped chorus frog. The bullfrog, a non-native species, is also located in the Cherry Creek. In recent years, bullfrogs have contributed to the decimation of native amphibian species populations at the creek.
