were it not for the hydrographic data 

 accumulated by the Survey during many 

 years of observation and measurement. 

 In addition to that, the work of private 

 individuals is constantly facilitated b.y 

 the same records. No large engineer- 

 ingenterprises are now undertaken with- 

 out reference to the Survey's records 

 concerning the supply of water avail- 

 able at the chosen site. The South 

 Platte Land and Reservoir Company, 

 which has under way canals and reser- 

 voirs that probably aggregate $500,000 

 in value, has established stations at. 

 Orchard and Kersey, Colorado, because 

 of the superior hydrographic advantages 

 offered by those localities. The choice 

 of those points is directly traceable to the 

 data compiled by the Survey. Equally 

 important is the fact that projects that 

 would have resulted disastrously have 

 in numerous cases been abandoned after 

 a study of Survey records that threw 

 light on the probable outcome. Data 

 concerning the flow of water on the 

 Arkansas and South Platte rivers pre- 

 vented the expenditure of great sums 

 of money on the state canal in the first 



instance, and upon the Pawnee Pass 

 reservoir project in the second. 



Survey data seem to be in great de- 

 mand as unimpeachable testimony in 

 the legal controversies that have arisen 

 in this state in regard to irrigation mat- 

 ters. A most notable instance is the 

 case of the Colorado and Southern Rail- 

 road vs. The Denver Union Water Com- 

 pany, in which the sum of $100,000 was 

 involved. 



Data obtained by the Survey in re- 

 gard to the amount of water power 

 available at certain places have influ- 

 enced the plans of the Glenwood 

 Springs Light and Power Company, 

 the New 7 Century Light and Power 

 Company, and also proposed power 

 companies on Clear and St. Vrain's 

 creeks. None of these projects has yet 

 been carried to a conclusion, but some 

 of them will undoubtedly be eventually 

 constructed. 



Colorado cities seeking a suitable 

 water supply have frequently consulted 

 data obtained by the Survey. In the 

 case of Durango, in southwestern Colo- 

 rado, the discharge of Florida River was 



AN ARTESIAN WELL IN THE WESTERN IRRIGATION COUNTRY.
