The "rock castle" of Castle Rock, Colorado

Douglas County is a county located in the U.S. state of Colorado. As of the 2020 Census, the population was 357,978. The county is named in honor of U.S. Senator Stephen A. Douglas. ^[1] The county seat is Castle Rock. ^[2]

Douglas County is part of the Denver–Aurora–Lakewood metropolitan statistical area. It is located midway between Colorado's two largest cities, Denver and Colorado Springs, and contains a portion of Aurora, the state's third-largest city. Douglas County has the highest median household income of any Colorado county or statistical equivalent. It is ranked seventh nationally in that category.

Overview

Douglas County is lightly wooded, mostly with ponderosa pine, with broken terrain characterized by mesas, foothills, and small streams. Cherry Creek and Plum Creek rise in Douglas County and flow north toward Denver and into the South Platte River. Both were subject to flash flooding in the past, Plum Creek being partially responsible for the Denver flood of 1965. Cherry Creek and Plum Creek are now dammed.

Most residents commute to workplaces elsewhere in the metropolitan area outside of the county. Suburban development is supplementing the traditional ranching economy of the county.

History

Douglas County was one of the original 17 counties created in the Colorado Territory by the Colorado Territorial Legislature on November 1, 1861. The county was named in honor of U.S. Senator Stephen A. Douglas ^[3] of Illinois, who died five months before the county was created. The county seat was originally Franktown, but was moved to California Ranch in 1863, and then to Castle Rock in 1874. Although the county's boundaries originally extended eastward to the Kansas state border, in 1874, most of the eastern portion of the county became part of Elbert County.

Geography

According to the U.S. Census Bureau, the county has a total area of 844 square miles (2,190 km²), of which 841 square miles (2,180 km²) are land and 2.6 square miles (6.7 km²) (0.3%) are covered by water. ^[4]

Parks and recreational areas

Three state parks fall within Douglas County: Castlewood Canyon State Park, Chatfield State Park and Roxborough State Park. Parts of the county lie within the Pike National Forest and were crossed by the historic South Platte Trail.

Recreation trails in the county include:

• American Discovery Trail
• Colorado Trail
• Devils Head National Recreation Trail
• Highline Canal National Recreation Trail
• Platte River Greenway National Recreation Trail
• Ridgeline Open Space Trail

The Rueter–Hess Reservoir, when filled, may provide significant recreation, including fishing, hiking, and nonmotorized boating. If filled to capacity, surface size would be 1,140 acres, making this a fairly significant reservoir in Colorado and Douglas County's largest body of water.

Cherokee Ranch and Castle is a 3,400-acre privately owned property which forms a 12,000-acre open space with the Highlands Ranch Backcountry and Daniels Park. The area is host to a variety of animals and the Cherokee Ranch petrified forest. ^{[5] [6]}

The Prairie Canyon Ranch, at 4620 CO-83, about 10 miles (16 km) south of Franktown, is a Douglas County Open Space. It is a working cattle ranch on 978 acres (3.96 km²), open to the public on special events. ^{[7] [8]}

Politics

As a primarily exurban county, Douglas County has long been known as a Republican stronghold. In the 2012 election, Mitt Romney won 62% of the vote. Douglas County has become more competitive in recent years due to voters leaving the Republican Party, with Donald Trump winning 55% of the county's vote in 2016, and only 52% of the vote in 2020. Joe Biden, meanwhile achieved the highest vote share for a Democratic presidential nominee in the county since 1964. ^[17] In 2022, incumbent Democratic governor Jared Polis lost the county by a razor-thin margin, winning nearly 49% of the vote. ^[18] However, Democratic strength is mostly limited to northern Douglas County, including Highlands Ranch, Lone Tree, and Meridian, while the rest of the county is still strongly Republican. ^[19]
