Standley Lake is considered to be Westminster’s largest body of water. With over a thousand acres of surface area, the reservoir was originally built to supply water for agricultural irrigation northwest of Denver.
Now, it mainly serves different cities in Denver in terms of drinking water supply; including Westminster, Northglenn, and Thornton. There is a day-use fee for cars, or an annual pass may be purchased. The park is operated by the City of Westminster and the history of local use of Standley Lake goes back more than a century.
Other than serving as the municipal water supply, Standley Lake Regional Park is also open for recreational use. Activities such as camping, hiking, bicycling, and wildlife viewing are some of the activities that could be enjoyed within the park premises. Visitors are also welcome to fish and ride their powerboat in the lake (by permit only).
There is a fee to enter the park but free parking is available until sunset. There are different fee setups for different access types like bringing your own paddle craft. Annual passes are also available with special fees for seniors, handicapped individuals, and vets or active military.
Park rules and regulations are set in place for a more peaceful and pleasant experience for all visitors of the park. All guests are expected to abide by these rules and regulations.
