Show Record I arrived at Green River, Utah, on September 27, 1928. 147 The Government maintains a gauging station at the town of Green River for the purpose of determining the daily flow and from that the monthly and yearly run- off of the Green River. Measurements are made of the discharge which is measured by determining the 148 width, depth and velocity of the stream. The measurements of the depth are made by sounding and the measurements of velocity are 149 made with a current meter. There are also gauging stations main-tained at Cisco, located about thirty miles upstream from Moab, and at Lee's Ferry, and there are no intermediate gauging stations between these points. 150 Exhibit No. 79, entitled " Hydrographs in Certain Colorado, Green and San Juan River Gauging Stations from 1901 to 1927", was received in evidence. 150- 151 Exhibit 79 shows the daily flow of the Green, Colorado and San Juan Rivers for the period between 1920 and 1928. The sum of the flow shown at Cisco and of that shown at Green River will disclose the flow of the Colorado River at the junction of the Green and Colorado. Add to this sum the flow of the San Juan as shown at the Bluff gauging station and you have the combined flow 152 of the Colorado at Lee's Ferry. I heard Mr. Eddy's testimony as to the dates when he was on the Green River, towit, in June, 1927. A reference to Exhibit 79 discloses that on June 27, 1927, there was a flow of 30,000 second feet at Green River, Utah. The flow dropped off the latter part of the month to 22,000 and came up to 30,000; dropped down to about 23,000; went up to 25,000. At that same time the maximum flow at Cisco was Around 43,000 second feet. So in all probability the flow at the end of June was approximately 70,000 second feet in Cataract Canyon. 153 The record Mr. Eddy gave of 119,000 second feet was the peak flow at Lee's Ferry during that flood, and if you take 50,000 second feet that came from the San Juan, the flow that Mr. Eddy described - 22- |
