Twin Lakes Open Space

Twin Lakes is peaceful neighborhood park that lies within the developed areas of Gunbarrel. This 42-acre park contains two manmade lakes, irrigation ditches andTwin Lakes surrounding wetlands that have evolved into valued habitat and travel corridors for wildlife. Great blue herons, red-winged blackbirds, Northern Harriers, Red-tailed hawks, coyotes, fox, and other birds and mammals frequent the area. Neighbors walk, jog, view wildlife, and enjoy the lakes’ scenic values.

Dogs have off-leash access to the West Lake, and the trails are multi-use.

History

Twin Lakes Open Space was purchased in January 2002. The reservoirs are used by the Boulder & Left Hand Irrigation Company (B&LHIC) to store and transport agriculture water.

Twin Lakes Open Space is located within the developed area of Gunbarrel. A majority of the residences are in the unincorporated county while the commercial and industrial uses have been annexed into the City of Boulder.

The Boulder & Left Hand Irrigation Company has been operating the reservoirs since 1910. In 1957 IBM purchased nearly 500 acres of agricultural property north of the Gunbarrel area. Residential and commercial development began in response to the development of the IBM plant in 1965.

Twin LakesIn 2002 Boulder County and B&LHIC reached an agreement in which the county would purchase fee interest in the land and the recreation rights on the reservoirs while B&LHIC would retain the right to use the reservoirs to store water.

Twin Lakes Open Space is a unique property requiring special consideration for management because of its ecological characteristics, patterns of previous use and proximity to urban development.

Trails

Twin Lakes offers 3.1 miles of scenic trails surrounding the lake areas. Fishing is permitted, and dogs are allowed off-leash access to the West Lake.

Access

Twin Lakes can be accessed by taking Jay Road to 63rd in Gunbarrel. Go north on 63rd and turn right onto Nautilus Drive, where there is an industrial park entrance, and follow around to Nautilus Court.
