Show 6064 4067 survey from Lees Ferry in August, 1921, did you not? A July. Q And you were working in August? A Yes, sir. Q Now, assume that on a certain day in August, you found the level of the river at a certain spot, and it appears that on that day the gage at Lees Ferry showed approximately 13 ½ feet. Now, you worked up the river spot, and taking a level, and on that day the gage at Lees Ferry showed 19 ½ feet -- that is, a difference of 6 feet. What sort of an ad-justment do you make on your profiles; because there is a difference in the river level of 6 feet, and if you have been working up day by day, how do you adjust that? that we adjusted some such differences as that arbitrarily in the field. for instance, that would mean an abnormal flow, duced to the grade or the elevation at which we were working; say, when the gage read 13 ½ feet; in a few days it appeared that this was a period of the river gradually falling. |
