This report is the fourth of a series entitled " Water powers of the Cascade Range, " prepared by the United States Geological Survey under a cooperative agreement with the Washington State Board of Geological Survey. Part I contains data on the drainage basins of Klickitat, White Salmon, Little White Salmon, Lewis, and Toutle rivers and was published in 1910 as Water-Supply Paper 253. Part II relates to the drainage basins of Cowlitz (except the Toutle) , Nis- qually, Puyallup, White, Green, and Cedar rivers, on the west side of the Cascade Range, and was published in 1913 as Water-Supply Paper 313. Part III refers to the Yakima basin, on the east side of the Cascade Range, and was published in 1916 as Water-Supply Paper 369. The Wenatchee and Entiat basins, Described in this report, lie in the central part of the State of Washington, on the eastern slope of the Cascade Range. The location of tljie areas covered by Parts I, II, III, and IV is shown in figure 1, and a map of the region under consideration forms Plate I. : The data on which this report is bas^d consist of daily stream- flow records, miscellaneous measurements, river plans and profiles (Pis. VII, A-E, VIII, and IX, A and B, at end of volume), reservoir surveys, topographic maps, and the results of reconnaissances made by the United States Geological Survey, supplemented by a large amount of information furnished by State officials, private individ uals, and officials of private enterprises. The potential water power in Washington, according -to official estimates,1 is greater than that of any other State in the Union, but irrigation projects susceptible of cheap development at small in itial outlay are neither so numerous nor so extensive in Washington as in
