Show 6060 505 Stabler _ D 4063 measurements haven been made at a number of points. By The Special Master: Q Well, Mr. Stabler, assuming that at Lees Ferry, or at any one point, this river is testified to to carry a cer-tain number of thousands of tons of sediment, what becomes of that sediment at the dams? A If and when built, the greater part of it will be dropped out, normally, in the upper part of the headwater of the dam, at first, gradually fill down toward the dam itself; eventually, the reservoir capacity will be very materially decreased by reason of sediment deposits. Q Well, the bed of the river would be raised, would it not? As the sediment is held back by the dams, what ef-fect does that have up the river? Does it have an effect on the bed up the river from the dam? A Of course, as far back as the normal flow line of the dam extends, that is, the water surface of the river, there would, of course, be no material change; the deposit at the upper end of that flow line would tend to flatten the slope above a short distance; in other words, you would have |
