Show 6126 4126 Q Between what dates? A The particular dated I gave were between November, 1924, and July, 1927. Q That would be not a progressive scour, but it would be changes back and forth, I suppose? A Probably changes back and forth, depending upon the floods that may have occurred between those two dates. The dates as shown on the plate and on the cross- sections. Measurements were made approximately everyday at the Lees Ferry gaging station. It would be possible to show the change each and every day, by means of plates like this ( in-dicating). By Mr. Blackmar: Q Well, how are those measurement taken? A Those measurements are taken from a cable car. The station is a fixed point, and a cable car with a load weight varying from 75 to 100 pounds in connection with the measurements of the daily discharge. By The Special Master: Q Let me see if I understand this. Do you mean to say that between those two dates the river became 17 feet deeper at that point? |
