Explore the Standley Lake Story Map to see all that we have to offer!

Standley Lake is a multi-use recreation and water-storage facility, and is the drinking water supply for Westminster, Northglenn, and Thornton. With 1,063-acres of surface area, Standley Lake is Westminster’s largest body of water. It is also the Denver metropolitan area’s third largest reservoir. In addition to hiking, bicycling, camping, wildlife viewing and other park-based recreational activities, the lake offers visitors numerous opportunities for fishing and paddling. Standley Lake is a "paddle only" reservoir and does not allow the use of motors or trailered boats. There is a wealth of history surrounding Standley Lake that dates back over one hundred years. 

Standley Lake Regional Park is owned and operated by the city. While the public has access to the parkland and recreational use of the lake, the water rights are jointly owned by the cities of Westminster, Thornton, Northglenn and the Farmers Reservoir and Irrigation Company (FRICO).  The dam, which is one mile long, is private FRICO property and is off-limits to the public.  

Standley Lake is located at 100th Avenue and Simms Street .  Along the south side of West 100th Avenue at Owens Street is a small parking area that provides free walk-in and bicycle access to the park. Another small parking lot that requires no entry fee is located south of the lake at West 86th Parkway and Simms Street. The free parking lots close at sunset (official MST) daily.
