Stillwater Lakes located in western Nevada has been experiencing an astounding number of fish and waterfowl deaths since August 1986. This problem is explored through a multivariate statistical analysis applied to a water quality data set collected from the Stillwater area. Correlation among the Stillwater Lakes with other lakes/reservoirs and with various chemical constituents was investigated. The area was found to be extremely high in boron, total dissolved solids (TDS), arsenic mercury, and strontium. A direct correlation between boron, TDS, and specific conductivity was also observed. Remote sensing analysis of the Stillwater area was used and involved image enhancement of Landsat Thematic Mapper data to evaluate the geography, hydrology, and geology of the region.
