Standley Lake Regional Park – Westminster, CO | Boating, camping, fishing, hiking and swimming

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 the 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. History of local use of Standley Lake goes back more than a century.
