As the river goes down, more rapids will appears? " THE SPECIAL MASTER: Better ask him whether more rapids appear as the river goes down or goes up, which. " A. As the river rises, usually a number of rapids are obliterated on account of the height of the water. " BY MR. BLACKMAR: " Q. When you say obliterated, instead of having several small rapids you will have one large one? " A. Yes. " BY THE SPECIAL MASTER: " Q. Does the presence of rocks on sandbars make any difference in high water? What effect would it have? " A. Its influence would be shown; it depends entirely on the stage of water. With a thirty- foot rise in the lower Colorado, in Marble canyon, you might not see the result on any rapid at all, on account of a sudden rise, but in a twenty- foot rise you might see quite an influence in the surface of the water, it would be perceptible, yet it wouldn't be what a swift water river man would call a rapid. " Q. So far as the difficulty of getting down the stream or getting up, the presence of rocks and so on contributes more to the difficulty then the swiftness of the water, doesn't it -- I mean in going down stream. |
