The lower narrow section is sometimes called Waterton Canyon, referring to Waterton, Colorado.

Hildebrand Ranch is located near Littleton, Colorado. In 1866 Frank and Elizabeth Hildebrand settled in Deer Creek and homesteaded on 160 acres. In the 1950s there was a plan that was authorized to control flooding in Denver but the funds never came. In 1971 the Army condemned 333.73 acres of the ranch and created Chatfield Reservoir. In March 1973 Denver leased 750 acres from Chatfield and 67 for the Denver Botanic Gardens which included the ranch's original buildings. In February 2001 Jefferson County Open Space purchased 1,450 acres of Hildebrand Ranch

Roxborough State Park is a state park of Colorado, United States, known for dramatic red sandstone formations. Located in Douglas County 20 miles (32 km) south of Denver, Colorado, the 3,339-acre (13.51 km2) park was established in 1975. In 1980 it was recognized as a National Natural Landmark.

Chatfield State Park is a state park located in Douglas and Jefferson counties of Colorado, United States. The park centers on Chatfield Reservoir, a 1,423 acre surface area lake fed by the South Platte River and two other creeks, including Plum Creek.

Chatfield Dam and Reservoir is a dam and artificial lake located on the South Platte River, south of Littleton, Colorado. The dam and reservoir were built by the United States Army Corps of Engineers as a response to the disastrous flood of 1965. In addition to its primary purpose of flood control, it serves as one of many water supply reservoirs for the city of Denver, Colorado. In 1966, the U.S. Atomic Energy Commission projected a total federal cost of $74 million. Construction of the project was begun in 1967 and the dam was completed in 1975. The massive breastworks of the dam measure approximately 13,136 feet (4,004 m) in length with a maximum height of the dam of 135 feet (41 m) above the streambed. The normal depth of the lake is 59 feet (18 m) at its deepest point. This means the dam towers 88 feet (27 m) above the mean surface of the reservoir. The lake drains an area of more than 3,000 square miles (8,000 km2). The 1,500 acre (6 km2) lake has a conservation storage capacity of 27,000 acre⋅ft (0.033 km3) with a flood-control pool of over 350,000 acre⋅ft (0.43 km3)

The park has been occupied by humans as early as 10,000 years ago. The earliest evidence is a 10,000-year-old Folsom spear point found in the park. Numerous fire pits and stone tools have also been found in the area. A human skull found at a burial site has been carbon dated to approximately 1,900 years ago.

Plum Creek is a stream in Douglas County, Colorado, United States. It is formed by the confluence of West Plum Creek and East Plum Creek near the intersection of North Perry Park Road and Manhart Avenue in Sedalia. Prior to the construction of Chatfield Reservoir in the 1960s and 1970s, Plum Creek merged with the South Platte River in far northern Douglas County. Now, however, it empties into the southern side of the reservoir itself, just west of Santa Fe Drive and within the boundaries of Chatfield State Park. The Chatfield Storage Reallocation Project, scheduled to start in fall, 2017, will add capacity to Chatfield Reservoir and raise its level about 12 feet. This higher reservoir level will cause the mouth of the creek to move about 7,000 feet further upstream. As part of the expansion project, a mitigation project will also be undertaken to deal with increased sediment deposition and channel erosion along Plum Creek caused by increased urban runoff.

The North Fork South Platte River is a tributary of the South Platte River, approximately 50 miles (80 km) long, in central Colorado in the United States. The river is located near the headwaters of the South Platte in the Rocky Mountains southwest of Denver, draining a rugged area of the Front Range just south of the basin of Clear Creek. It rises at the continental divide near Webster Pass (Colorado) in northwestern Park County, flows through a canyon to the southeast, and is joined by Geneva Creek at the town of Grant. Downstream from Grant it is followed by U.S. Highway 285 until Bailey, where it cuts through a remote section of the foothills. It joins the South Platte from the west at the lower end of the Platte Canyon in the mountains approximately 20 miles (32 km) southwest of Denver. The lower part of the river is flanked by several small mountain communities, including Buffalo Creek and Foxton, in the extended geographic region of the Platte Canyon. The basin of the river is separated from South Park to the south by Kenosha Pass. The lower 10 miles (16 km) of the river form part of the boundary between Jefferson and Douglas counties.
