GEOPHYSICS: Sliding Under Lake Tahoe

Water Quality Management Plan for the Lake Tahoe Region

This section of the EIS identifies and assesses the potential cumulative impacts related to the Regional Plan Update alternatives. For purposes of this analysis, a cumulative impact is “the impact on the environment which results from the incremental impact of the action when added to other past, present, and reasonably foreseeable future actions, regardless of what agency or person undertakes ...

Evidence for deep magma injection beneath Lake Tahoe, Nevada-California.

A deep earthquake swarm in late 2003 at Lake Tahoe, California (Richter magnitude < 2.2; depth of 29 to 33 kilometers), was coeval with a transient displacement of 6 millimeters horizontally outward from the swarm and 8 millimeters upward measured at global positioning system station Slide Mountain (SLID) 18 kilometers to the northeast. During the first 23 days of the swarm, hypocentral depths ...

Ecological Changes in Lake Tahoe: The Influence of Introduced Species

Prior to large changes in community structure and water column nutrient concentrations, Lake Tahoe’s community assemblage was relatively simple with 12 orders of zoobenthic taxa, 6 zooplankton species, and 8 fish taxa (Juday 1906, Miller 1951, Frantz and Cordone 1996, Chandra 2003, and Vander Zanden et al. 2003). The benthic invertebrate community consisted of one endemic, a wingless form of st...

Aircraft measurements of nitrogen and phosphorus in and around the Lake Tahoe Basin: implications for possible sources of atmospheric pollutants to Lake Tahoe.

Atmospheric deposition of nitrogen (N) and phosphorus (P) into Lake Tahoe appears to have been a major factor responsible for the shifting of the lake's nutrient response from N-limited to P-limited. To characterize atmospheric N and P in and around the Lake Tahoe Basin during summer, samples were collected using an instrumented aircraft flown over three locations: the Sierra Nevada foothills e...
