Show Record I have made a careful search. 4114 Complainant's Exhibit No. 618, being fourteenth census of the United States, 1920, department of Commerce, was received in evidence. Complainant's Exhibit 619 of the annual report of the Director of the United States Coast and Geodetic Survey to the Secretary of Commerce for year ending June 30, 1922, being the reports of F. W. Huff and F. E. Joekel, which deal with level lines in and through Glen Canyon, was received in evidence. William Glen Hoyt, recalled, and testified for complainant on direct examination as follows: 4115 Exhibit 88 in a compilation of all of the stream flow records collected by the United States Geological Survey at the gaging stations on the Green, Colorado and San Juan Rivers. 4123 Gaging stations are selected and operated by the Geological Survey at sections where the bed is as stable as possible, and in sections where the river is straight, where the velocities are distributed uniformly throughout the cross- section. 4124 Plate 2- A of Exhibit 82- A is a cross- section of the channel at the measuring cable at Lees Ferry, showing range of change and the characteristic changes in the channel itself caused by scour and fill. The curves are plotted cross- section from actual field measurements made during the course of determining the flow of the water during a period from November 22, 1924, to July 11, 1926. 4128 In other words, this chart shows the rapidity of the amount of scour and fill taking place in the Colorado River at Lees Ferry, as shown by actual measurements made. Similar information is shown for each of the gaging stations on plates 1- A, 2- A, 3- A, 4- A, and 5- A. The data produced in this exhibit can only be produced 4129 at the gaging stations. They are the only places where measurements of this kind have been taken as far as the geological survey is 592 |
