Show Record 5357 wash, when for a few hours it was hard to find. Even on such oc-casions there has always been a channel, if you knew where to find it. When sand and material comes down from the side washes the length of time that any change thus created may remain depends on the place where it occurs; for instance, between the Wimmer ranch and Green River the river falls 2.8 feet per mile and where there is such a current, the sand or material brought in from side washes is dislodged and cleaned out in a few hours; at other points it may take a day or two for the channel to be cleaned again and back to its old condition, but in a few days the river will do its own housecleaning. In response to questions propounded by the Special Master Mr. Wolverton testified: 5358 What I have said holds true in Stillwater Canyon as else-where; Stillwater Canyon is no different from Labryinth Canyon. In fact the water is not as quiet in Stillwater Canyon as it is farther up; it takes longer for the channel to clean itself down in those canyons than up above where the water is swifter. After you have made the first trip through a place where sand and other material has come down from a side canyon you have no difficulty in finding the channel there on later trips, but 5359 you have to keep a sharp lookout. You can not see by looking into the water where the bottom of the river or channel is. There is always a slight agitation of the surface of the water in the cha-nel when the wind is not blowing; the drift usually follows the main channel; when the wind is blowing the high waves are only in the deep water and you follow them. You keep a sharp lookout for the signs of the channel to which I have just referred. The channel is usually well defined but a rock may roll down from a 5360 side current so that some of the water may go to one side or to the middle of the river. A swift part of the stream may not be its channel. There may be an obstruction of some kind that has gotten |
