Show Record running up stream where it went down through an eddy, the current has crossed over to the other side. We come up through that eddy water to get the easy water coming up stream - come up the old channel to get the easy water. In high water, when a flood condition arises, the channel is there just the same. The low part of the river does not go dry, and when four feet more of water comes 4793 in, the channel is there just the same. In coming up stream, whether or not you take the same channel that you took going down, depends on the condition of the water. In low water you have to take the same channel. In high water you take the back eddy water, a part of which runs up stream quite a distance. In the fall of the year coming up stream you have to take the real channel. I mean by that the channel that you took going down. You have to take the same channel coming 4794 back. That has been my practice. As to the effect of the annual high spring water on the beds of these streams: We get a March raise from local snows that comes up rather fast, then it goes down again, then it comes up very slowly. Natural high water of the river comes up slowly. It requires more space and it will change the current. The current runs in low water but one place, in the low places of the river. In high water it hits a solid rock bank, for instance, and changes the current of the river. There may be a sand bar here today and the 4795 current will cut across in high water and cut that sand bar cut. The main pathway of navigation in the river is what we call the channel. I mean the main current of the river does not run in the channel only in low water. The swiftest portion of the river may or may not be in the channel. As water raises higher it hits the rock and throws it quicker across the river, changes the main speed of the current where the channel was in low water. Substantially I mean to say that in higher stages of water, the swift- 4797 est water is not always found in the low water channel. When I went back in 1903 for the California Edison 704 |
