The present lakes, occupying in many instances the lowest depressions in the 

 Quaternary lake basins, are given in the next section. The chemical data con- 

 cerning both the Quaternary and the recent lakes and their basins will be given in 

 another section of this report. 



SURFACE WATERS. 



Complete data are not available for the determination of the total run-off in the 

 basin region. From the Water Supply Papers of the United States Geological Survey 

 it is possible to secure data for the principal streams, but many small streams of local 

 importance are to be found in the mountains of the Great Basin, and for these we have 

 practically no data. These streams contribute to the underground-water supply, but 

 seldom do their waters reach the surface of the playas except in periods of vmusual 

 rainfall. The ponds and shallow lakes resulting are quickly eA^aporated. 



The principal streams are: In western Utah, the Weber, Bear, Logan, Spanish Fork, 

 Sevier, and Prove; in Nevada, the Humboldt, Truckee, Carson, Walker, Reese, 

 Quinn, and Araargosa; in California, Susan River, Owens River and tributaries, 

 Leevining Creek, Mill Creek, and Mojave River; in Oregon, small creeks and streams 

 which contribute to the lakes in southern Oregon. Such data as are available for 

 the above streams are given in Tables V, VI, VII (Appendix).
