<br />.:l/Ub <br /> <br />know what you do to a compact when your storage <br />becomes of little value to you on the fact <br />that it has silted up. Now this is down in a <br />country where you do get plenty of silt. There <br />isn't any question about that. I would like <br />to know what increased sedimentation would take <br />place by the fact that you do put a 10,000 <br />acre-foot pool in there. And if you stop this <br />water and make it a permanent pool, (we are <br />stopping all waters that come in and they are <br />certainly going to unload some silt; I don't <br />think it is possible they are going to pick <br />it up and carry it out with them), what effects <br />would the pool have on the life of this stor- <br />age project? How far down the line do we go <br />when the pool is being silted up before it <br />has a direct effect on the Kansas-Colorado <br />Compact? As I remember the compact, the <br />ditches below use about 165,000 acre-feet; <br />Kansas would be entitled to about 100,000 <br />acre-feet; that's about 265,000 acre-feet. <br />How far down the line, when you remember the <br />fillings of this reservoir come erratically? <br /> <br />I <br /> <br />According to the minutes of our ditch <br />company, about once every ten years we had our <br />old dam wash out. So you can assume that <br />about once every ten years you'll get a pretty <br />good flood down the Arkansas. And the last <br />time that a good flood came down the Arkansas, <br />it did not fill the conservation pool and I <br />think they lost 44,000 acre-feet to siltation. <br />So let's look down the line just a little bit. <br />Let's not look just at this year and next year; <br />let's look down at three or four fillings from <br />now. How much have you lost to sedimentation? <br />How does it effect the compact? Also when you <br />put this water in, you measure in, we'll say, <br />50,000 feet, what percent of that is mud that <br />doesn't come out in the form of water? How <br />are you going to determine that? You can go <br />in and survey the pool site and determine what <br />has been left there, but how can you determine <br />what comes in on a large flood that is measured <br />in? And certainly this water would have to be <br />measured in and measured out, as it came in, <br /> <br />I <br />
