Show Record As to the various indications of high and low water marks I had a hand level with me and I checked up a number of those marks along and the marks made by Lieutenant Leeds were reasonably accurate. Upon that trip I did use the maps marked Exhibits 481 to 491 inclusive. I was particularly concerned about the various 3685 riffles in the river and Lieutenant Leeds had made detailed surveys of these, so that as I went down the river I conculted these maps and compared them with the conditions on the ground. So far as I was able to judge the maps were accurate as to the location stretch of the river for which I did not have maps. It seemed to me that the maps pretty well covered what the situation was on the river, I define a riffle as a shallow place in the river where it might impede navigation or it might impede a boat; the velocity is high and the water is shallow. I make no distinction between 3686 a riffle and a rapid, except perhaps a rapid is considered a large riffle. Between Greenriver and the mouth of the San Rafael I used a pole and sounded the depth of the water in a number of places. I cannot now tell you the depth. When we crossed the mouth of the San Rafael we struck the propeller on the bottom, on rock there, and at that time the river was flowing, I judge, 15,000 to 20,000 second feet. 3687 Attention is called to sheet No. 44 of Exhibit 94 which are the gage readings at Greenriver for the month of June, 1914. 3688 From the mouth of the San Rafael down to the junction we went down the river pretty rapidly. It seems to me I encountered sand bars. I went down to the junction and a few miles below on that trip and then came back to Greenriver, Utah. This was in a power boat. It seems to me that I was about a day and a half or two days going down and about four or five days coming back. It seems to me that I encountered quite a few sand bars coming back. 524 |
