PROJECT SPOTLIGHT:
Cherry Creek Valley Ecological Park Drainage Improvements
The Southeast Metro Stormwater Authority (SEMSWA), the Urban Drainage and Flood Control District (UDFCD), Arapahoe County Open Space and the Cherry Creek Basin Water Quality Authority (CCBWQA) would like to announce that a stream reclamation project design is underway for construction of drainage improvements along the Cherry Creek corridor. The intent of the project is to repair erosion in the active Cherry Creek channel that has been caused by urbanization from surrounding areas. The project improvements will:
Preserve and enhance drainage, wildlife, and recreational benefits
Protect and enhance water quality
Maintain the natural qualities of the corridor
An Open House meetingwas held on Wednesday April 18th at the Red Hawk Ridge Elementary School.
Some foam or suds in the stream is natural, especially as snowmelt runoff occurs in the spring. When aquatic organisms, such as algae, die and begin to decompose, fatty acids are produced. These fatty acids are very similar to those found in common soap products. Aeration of the water as it cascades over rocks causes the fatty acids to form foam, often accumulating along shorelines and river banks, and in coves and eddies.
Foam is generally white in color, breaks down relatively quickly, and smells like fish or earth. Foam from silt or erosion is usually a dirty brown color. In contrast, foam from detergent will have a noticeable perfume smell from the additives which give your wash a fragrant scent. Natural foam is often seen in early morning and is usually gone by midday.
If you see foam in the stream that looks like bubble bath, has a perfume scent and doesn't break apart easily, detergent may be in the stream. If so, please notify SEMSWA, 303-858-8844, or Arapahoe County Sheriff’s dispatch during non-business hours.
