<br />I <br /> <br />I <br /> <br />This shows some areas down in the lower valley there, where it is even <br />more salty. As you go west, the Mancos shale seems to have more effect <br />on it, and this is one of the little drainage area there. When the <br />water went down, we were out there and took some pictures. You can <br />see the salt entering the drain there. That is even more conspicuous <br />here. <br /> <br />The water that is coming into that drain is about seven or eight <br />thousand parts per million, that brown stuff that you see seeping <br />through there. <br /> <br />This is the way the water gets back to the river. This is one of the <br />irrigation systems, believe it or not, that we have out there in the <br />valley. It was pretty prevalent in the nineteen hundred twenties or so. <br />We are not into that anymore. I think, for the most part, we are <br />satisfied and we are going ahead with leveling the land and putting it <br />into first-rate irrigation ditches. <br /> <br />The ditches are put in in this fashion. First, we go through and <br />compact the area, and then we put the ditch in. This is a completed <br />di tch here with the automated gates. 'These are timed gates that are <br />set to go off at certain times iri. "order"to irrigate on a level basis. <br /> <br />MR. ADKINS: <br /> <br />T. J., are you above Or below Grand Junction? <br /> <br />MR. LONGLEY: <br />Juction area. <br /> <br />This is in the Grand Valley. This is all in the Grand <br />This particular area is just west of Palisade. <br /> <br />MR. ADKINS: <br /> <br />Thank you. <br /> <br />MR. LONGLEY: The ports there are on the level, and the ditch is on <br />a slope. We put the automated gate in between the two of them there, <br />and each set in this particular ditch has 60 of those ports. The water <br />goes out on an even basis onto the field. This is our crew that drilled <br />those ports out. <br /> <br />We have made some progress on how we handle this. When the concrete <br />is green, we can cut out a 3-inch hole, and then when we get ready, we <br />can knock that hole out, after it has cured, and then drill through the <br />barrier there between the ditch and the field. And this way, we can <br />obtain a very uniform irrigation procedure. <br /> <br />The Soil Conservation Service has a program that determines the length <br />of run and the kind of soil and the amount of water that is available, <br />and a number of things. They determine the optimum furrow time of <br />irrigation and the optimum amount of water to go down through the field. <br />On this Almirez place where we were working with the demonstration <br />project -- and by the way, the ASC Committee has used these demonstra- <br />tion projects extensively in their preparation for the oncoming project <br />that is going on out there now. In other words, they are going to use <br />the same kind of irrigation practices as this and level irrigation and <br />gated .pipe and automation, in order to get the job done. <br /> <br />These demonstration projects have really helped to pave the way into <br /> <br />-23- <br />
