This is the actual siltation, and I <br /> think it is interesting to note that it is substantially <br /> within the estimate. <br /> MR. KNAPP; I think there is another point that might <br /> be brought out from the figures we now have. Of the 26,131 <br /> acre feet, the acoumulation in the entire survey--25,428 acre <br /> feet has accumulated in the conservation pool. You will re- <br /> call that the oommittee believed that as time went on <br /> approximately one-third of the silt might accumulate in the <br /> flood and two-thirds in the conservation pool. Of course, <br /> the accumulation in the higher elevations, that is, in the <br /> flood pool, will not take place until there is storage in <br /> the flood pool. Thus we have up to the present time, prao- <br /> tioally the total silt accumulation in the conservation pool. <br /> MR. VIDAL: Roughly the conservation pool has been losing <br /> 35,000 acre feet plus a year. <br /> MR. KNAPP: You are dividing the 25,000 by-- <br /> MR. VIDAL: Roughly dividing 26,000 by 7, it le over <br /> 3500 feet a year. <br /> M}' . KNAPP: I took it as for the year 1948. 1 think <br />
