Summary
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 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.

Nitrate concentrations appeared to increase over time at one of two long-term
ground-water sites. Orthophosphate concentration decreased while specific
conductance increased at one of the two sites, but no trend was detected at the
other site for either parameter. No trends were detected for phosphorus,
biologically-available iron, water temperature, or pH at either of the
long-term sites. Trends in ammonia and organic nitrogen plus ammonia
concentrations were not evaluated because a majority of the values were below
the method detection limits.

There were no obvious spatial distribution patterns for nutrient concentrations
or field parameters in the Bijou Creek watershed. The altitude of the
ground-water table above sea level generally increased with increasing distance
from Lake Tahoe. The altitude of the ground-water table was greater than the
altitude of the surface of Lake Tahoe except at one ground-water site which is
influenced by a cone of depression around a nearby production well. Ground
water in the Bijou Creek watershed discharges to Lake Tahoe and may contribute
to the higher than normal turbidity in the area.
