Chemical history. No previous laboratory water chemistry data are 

 known for Kleinschmidt Lake. In the late 1950s, dissolved oxygen 

 monitoring was performed as part of a fishery enhancement effort. 

 Wintertime dissolved oxygen concentrations dropped to the 1-2 

 milligram per liter range at that time. Changes to lake volume and 

 depth since then may have altered the lake's wintertime dissolved 

 DO. 



Sediments. Arsenic was reported at a concentration ranking the 

 site toward the low end of the range shown by sites in the same 

 class. Copper, iron and zinc concentrations ranked mid-range in 

 comparison to similar sites. None exceeded the mean values for 

 soils and other surficial materials of the western United States.
