Ground-Water Reconnaissance of the Bijou Creek Watershed, South Lake Tahoe, California, June-October 2003
Abstract
A ground-water reconnaissance study of the Bijou Creek watershed in South Lake Tahoe California was done during the summer and early fall of 2003. This study provides basic hydrologic data for a region in the Lake Tahoe Basin in which a continuing loss of lake clarity is occurring in the a nearshore zone of Lake Tahoe. Wells, springs, and a surface-water site were located and basic hydrologic data were collected. Water levels were measured and water samples were collected and analyzed for nutrients. Measurements of water temperature, specific conductance, and pH were made at all ground-water sites where possible and at one surface-water site. Organic nitrogen plus ammonia, ammonia, and biologically- available iron concentrations generally were greater in the ground water in the Bijou Creek watershed than those observed in ground water elsewhere in the Lake Tahoe Basin. Nitrate concentrations were similar in the two groups. Phosphorus and orthophosphate concentrations generally were lower in the ground water of the Bijou Creek watershed compared to ground water from elsewhere in the Lake Tahoe Basin. Specific conductance and pH of ground water were similar between the Bijou Creek watershed and the Lake Tahoe Basin, but the temperature of ground water was generally greater in the Bijou Creek watershed.
