This also coy- o <br /> ers the situation as to accumulation of silt in Caddoa <br /> Reservoir sinoe the survey fixing the initial areas and <br /> capacities of John PGartin Reservoir, the tabulation trans- <br /> mitted to the engineering committee by letter on August 8, <br /> 1944. <br /> At elevation 3,770, which is an even numbered elevation, <br /> approximately two feet above the center of the outlet gates, <br /> the initial surveys of the area of the reservoir at that <br /> elevation was given as 710 acres, and in the survey of <br /> October 19, 1948, that is in Table 15 of the committee' s <br /> interim report, it is given as 542 acres, a loss in area <br /> of 168 acres at that elevation. The initial capacity at <br /> that elevation was given as 3,766 acre feet, and is now <br /> 542 acre feet, a loss in capacity at that elevation of <br /> 3,753 sore feet. <br /> I have then taken another elevation, 3,861 feet, which <br /> is on top of the conservation pool. The initial area in <br /> acres was 11,890. I was somewhat surprised to note in this <br /> new survey, Mr. Chairman, that the area at that elevation is <br /> now given as 12,194, a gain in surface area of 204 acres. <br /> Now, whether that represents a widening of the surface area <br /> by wave action, which might be possible, I do not know. <br />
