Show Record Greenriver, Utah, down to the Colorado and on the Colorado River from Moab down to Lees Ferry, it is my understanding that adjust-ments were made to the uniform stage of 10,000 second feet, in the light of gage height readings at Bluff on the San Juan, at Cisco on the Colorado and at Little Valley on the Green, as well as the gage at Lees Ferry. The topographers' field sheets and notes in every case show the water elevation as indicated by him. These were then adjusted to the gage readings that would represent a 10,000 second- feet stage in the light of the cross- section of the river at the point where the observations were taken, as well as the change in the stage, which would mean a lowering or raising 4071 accordingly: as where the river was at a stage of 15,000 second feet, it would mean bringing the level down, and where it was 5,000 or 6,000 second feet, it would mean bringing the level up, so as to represent a uniform stage of 10,000 second feet the whole way. That was done before these profile maps in Exhibit 10 were published. 4073 The adjustment would not change the general appearance 4074 of the profile at all, because the slope or gradient in general is such that a minor fluctuation makes very little difference in it, that is, over the whole course of the river, but it might make a difference of a few feet a some particular point, and would change the slope a few percent at that particular place. The general type of the slope of a rapid between low stage and high stage of water will vary. The rapid, however, will appear on any 4075 profile as a rapid. At low stage the rapid will appear shorter and sharper and at high stage longer and flatter. There will be a difference in appearance. Charles Arthur Bissell testified for complainant on direct examination as follows: 4076 I live at Chevy Chase, Maryland. I am a civil engineer. I have been employed by the Bureau of Reclamation since 1908. I was graduated a civil engineer at the University of Texas. |
