McMurdo Gulch Stream Stabilization

Protecting our water quality 

Stormwater improvements were conducted along the McMurdo Gulch to protect water quality and maintain a healthy stream system in response to impacts from urbanization. Evidence of erosion was observed in various locations along the channel. McMurdo Gulch is a western tributary within the Cherry Creek drainage basin and is located on the east side of Town.

Castle Rock Water, in partnership with the Cherry Creek Basin Water Quality Authority, completed two additional phases of stream stabilization in 2020. Stream stabilization occurred in four locations with a combined length of approximately 2,700 lineal feet, using a bio-engineering approach to environmentally fit the project into the natural surroundings. Work included grading the incised channel banks, reconstructing the channel bed, installing riffle drops and cascading boulder structures, and planting native grass and willows. Stream stabilization efforts such as these support the mission to preserve and protect water quality within the Town’s open space and the watershed.
