DETENTION BASINS FOR WATER QUALITY IMPROVEMENT AT A HIGH MOUNTAIN MAINTENANCE STATION
An evaluation of a detention basin system at a snow removal maintenance station is documented. In response to concerns by the US Forest Service, the basins were built as a mitigation measure to clarify storm runoff and snowmelt from the maintenance station before it entered Benwood Creek. The creek is a tributary of the headwaters of the South Fork of the American River. A portion of the creek was realigned. The three-basin system, completed in September 1981, is above elevation 7000 feet at the Echo Summit Maintenance Station in California. Sediment and dissolved materials in storm runoff and snowmelt from the maintenance yard were reduced. The capacity of the basins was approximately 10,000 cubic feet as measured in 1982. The basin riser outlets were fitted with grease rings, which retain most oil, grease, and floatables. Snow melt was sampled and tested in spring 1982. Samples were tested for turbidity, chloride, specific conductance, filterable residue, and chloride. Sediment accumulation in the basins was measured, and a biological assessment of the construction impacts on Benwood Creek was made.
