Barker Reservoir is a mountain reservoir adjacent to Nederland, Colorado (fig. 1), that supplies 40 percent of the drinking water for the city of Boulder, Colorado. The local geology is quite complex in this region of the Colorado Mineral Belt (Lovering and Goddard, 1950). The study area is primarily Precambrian igneous and metamorphic rock, except for Quaternary alluvium and colluvium in streambeds and drainages that lead to the reservoir (Gable, 1972). The reservoir is fed by North Beaver Creek and Middle Boulder Creek. Ground water that discharges into Barker Reservoir flows beneath residential developments on the north and south sides of the reservoir. Homes on both sides of the reservoir use individual sewage disposal systems (ISDS's) for disposal of domestic wastewater. The original document contains color images.
