<br />001\2. <br /> <br />,...... <br /> <br />6a. Poor Site for Dam Construction <br /> <br />('\ <br /> <br />with this porous overburden. In the past few years, water measurements <br /> <br />have been taken at Kersey and Narrows when the river was running about <br /> <br /> <br />10,000 cubic feet per second, which is a good full river within its banks. <br /> <br /> <br />There was a loss of from 1,000 to 3,000 cubic feet per second in this <br /> <br /> <br />distance. It would only be natural to assume that this water loss is to <br /> <br />the south into this porous aquafier and then to the east in the old river <br /> <br />channel. <br /> <br />The Bureau of Reclamation claims that they .can keop clown seepage <br /> <br />losses to the range of 27 to 48 cubic feet per second with a clay blanket <br />on the south side. <br /> <br />Tho Bureau of Reclamation states that the Bijou Creek will make an <br /> <br />excellent drainage canal for this seepage, which we cannot deny. But we <br /> <br />feel this will run a lot more than the projected 48 cubic fe~t per second <br />due to the overburden .soil structure of the whole south side of the <br /> <br />reservoir. <br /> <br />Woodward, Clyde and Sherrard indicate that the most important factor <br /> <br />in evaluating the geological situation is the location of the ancient <br />steep channel of the South Platte River. The old channel acts as a "by- <br /> <br />pass" in effect, as there is no way to control the deep underflow of the <br /> <br />river. The only "true Narrows" is the Hardin Site. It is debatable if <br />the Narrows Dam would hold water in an efficient mannero <br /> <br />,...... <br /> <br />I..J <br />
