<br />1 25/l00ths of an inch occurred on the seeded events. <br /> <br />2 This led to a percentage of approximately 250 <br /> <br />3 per cent, but the real water change over the entire winter <br /> <br />4 season was a total accumulation of 15/l00ths of an inch; and, <br /> <br />S if you related that to snowfall, the normal relationship is <br /> <br />8 l:lO so you would be talking about an inch and a half of <br /> <br />1 additional snowfall on those seeded events contributed by <br /> <br />8 this downwind effect, which again I point out is not a favor- <br /> <br />9 able event for the intended Project Area. <br /> <br />10 These are not exact figures, but these are approx - <br /> <br />11 mately correct as far as the range and the amounts indicated. <br /> <br />12 <br /> <br />: DR. FARRAR: I think we have heard some scienti- <br /> <br />13 <br /> <br />fic comment about the possibility of downwind effects from <br /> <br />14 <br /> <br />snowpack augmentation projects as far as 150 and 200 miles. <br /> <br />IS <br /> <br />could you comment on that? <br /> <br />18 <br /> <br />MR. HJERMSTAD: This is really under initial <br /> <br />11 <br /> <br />investigation. What you are talking about here is a distance <br /> <br />18 <br /> <br />approximately in the range of anywhere from 40 to lOO miles; <br /> <br />19 <br /> <br />and this is an extension, possibly an extreme extension, of <br /> <br />20 <br /> <br />what you are talking about. <br /> <br />21 <br /> <br />Again, these downwind effects were based upon <br /> <br />22 <br /> <br />initial concepts that were built into the earlier design of <br /> <br />23 <br /> <br />p~ograms. I feel that with the initial results of the pilot <br /> <br />24 <br /> <br />Project and indications indicating those storm characteristics <br />I <br />I <br />leading to this downwind effect and the adverse effect in the <br /> <br />2S <br />
