 the Federal Government to the development of water power iu the basin, and 

 government permits for power and reservoir sites. 



"From information now in hand it appears that more than G00,000 horse- 

 power can be developed and that approximately 500,000 acres of arid land can 

 ultimately be irrigated from Deschutes River and its tributaries. . . . The irri- 

 gable lands . . . are so situated on a plateau in the upper part of the basin 

 that the total flow of the upper river and its principal tributaries may be 

 utilized for irrigation ; and below the irrigable area the river flows in a deep 

 canyon having a fair slope and affording excellent opportunities for power de- 

 velopment. ... If the development of this stream is left to private capital 

 without public consideration of the effect of each new project on the compre- 

 hensive plan for the development of the valley as a whole enormous waste 

 may take place before the highest use of these waters is attained. . . . Ex- 

 tensive storage to supplement the flow of water in the lower river for power 

 should not be permitted on Deschutes River above Bend but should be confined 

 to Crooked River, from which stream the diversion of water for irrigation is 

 more difficult. With this exception, all the water in the upper two-thirds of 

 Deschutes River Basin should be reserved for irrigation." 



Quality of the surface waters of Oregon, W. Van Winkle {U. S. Geol. 

 Sm-vey, Water-Supply Paper SGS (1914), pp. 137, pis. 2, fig. 1). — ^This paper 

 describes the natural and economic features of Oregon and reports a cooper- 

 ative survey between the U. S. Geological Survey and the State of Oregon to 

 determine the chemical composition of the watei's of the State. 



A summary of the survey indicates that the river waters of Oregon are low 

 in mineral content and are very good for general industrial use and for irri- 

 gation. With one or two exceptions they carry small amounts of susi^ended 

 matter that can be readily removed. " The waters of John Day and Sandy 

 Rivers, however, are characterized by very finely comminuted suspended mat- 

 ter, the removal of which would be difiicult and would probably necessitate 

 filtration through rapid filters. Slow sand filtration can be used with many of 

 the river waters, but coagulation and rapid filtration is better suited to some 

 of them. 



" Erosion pi-ogresses most rapidly in the upper basin of John Day River, 

 where it is chiefly by corrasion, somewhat less rapidly in the Coast Range, 

 still less in the Cascades, and most slowly in the central part of the State. 



" The lakes of central Oregon are large and the waters of some of them are 

 economically important. Detailed studies should be made of the deposits and 

 brines in order to ascertain the location, nature, extent, and commercial value 

 of the residue." 



The water supply of Indiana {Ann. Rpt. Ind, Bd. Health, 31 (1912), pp. 

 533-541, figs. 4). — Data are given of examinations of 217 public water supplies 

 and 947 private water supplies in the State iu 1912. 



Of the public supplies 66 were streams, 63 deep wells, 42 ponds, 29 shallow 

 wells, and 17 springs. Of the 66 streams examined the waters of 36 were 

 good, of 10 bad, and of 20 doubtful. Of the 63 deep wells examined 57 were 

 good, 1 bad, and 6 doubtful. Of the 42 ponds examined the waters of 26 were 

 good, of 6 bad, and of 10 doubtful. Of the 29 shallow wells examined the 

 waters of 21 were good, of 3 bad, and of 5 doubtful. Of 17 springs the waters 

 of 10 were good, of 1 bad, and of 6 doubtful. 



The private supplies consisted of 587 shallow wells, 271 deep wells. 42 springs, 

 31 cisterns, and 16 miscellaneous. Of the shallow wells examined the waters 

 of 254 were good, of 246 bad, and of 87 doubtful. Of the deep wells examined
