approximately 25% lower than 1993 and 1994 measurements. Seasonal 

 measurements in 1993 and 1994 show approximately 10% difference in 

 salinity. Vegetation indicators show considerably higher lake 

 volume within the past few decades, implying significantly more 

 dilute water chemistry. The measured salinity range within the 

 lake basin was minor, amounting to approximately 5% in specific 

 conductance . 



Sediments. Sediment trace element concentrations are generally low 

 with respect to regionally and hydrologically similar sample sites. 

 Trace elements found above detection limits (arsenic, boron, copper 

 and zinc) occurred at concentrations below the regional mean soil 

 concentrations for these parameters (Shacklette and Boerngen, 

 1984) .
