MR. SPARKS: "1:1e are very happy to have you, :Mr. McColm and Mr. Rogers. From the United States Geological Survey we have Mr. \'1ally Miller and Mr. Frank Bell. Will you two gentlemen stand? They are the gentlemen who run our stream gauging program throughout the State of Colorado, and maintain the records on the Gunnison River among others. I would like to give a very brief resume of the Curecanti Project and what we can ex- pect in the way of construction and when it will happen and so on. If I make any mis- takes, we have ample authority here whom I trust will promptly correct me, both from my own staff and from the Bureau of Reclamation staff, I I It is somewhat difficult for you to see this map which we have prepared. This was taken from information furnished to us by the Bureau of Reclamation and by our own State Highway Department. First I will take the main unit of this project, the Curecanti unit, which is the Blue Mesa Dam. The dam site is just below the mouth of Black Canyon, just below the community of Sapinero, This dam is approximately 24 miles in length, if my recollection is correct, that is, the reservoir is approximately 24 miles in length, and will back water up to about Cooper's Resort, that is, the high water mark. You will notice that we have shaded parts of the reservoir, The parts in the heavy blue is that part below which the water is not expected to be drawn. In the recom- mended operation of this reservoir it provides that the water shall not be drawn down below an elevation of 7427 feet. That means that at its lowest point therefore, there will always be water up to about lola, As you can see, Soap Creek and Lake Fork are approximately the high water for the lowest point to which water would be drawn. There is virtually no draw- down during the period from June to October of each year so this reservoir does not fluctuate greatly as is the case of most reservoirs that are used exclusively for irrigation.
