<br />-2.- <br /> <br />This report is concerned with the clay potential existing in the <br />District area and the initial results of installations made with local clay <br />materials in canals and reservoirs. <br />Since the evaluation and development work is not complete, this <br />report also includes future plans for continuation of the work. The com- <br />pletion activities are being carried out as part of a state-wide clay <br />(including bentonite) inventory and sealing research program of the <br />Colorado State University Agricultural Program with funding as provided <br />by the Colorado Legislature and the Colorado Water Conservation Board. <br /> <br />CLAY SAMPLING <br /> <br />A comprehensive sampling of!!!:. clay deposits in the District area <br />has not been completed. It is believed, however. that a satisfactory <br />- <br />representation of the clays available within the District area has been <br />obtained. Information concerning each of the deposits sampled to date is <br />briefly outlined in Table 1 . starting at the upstream end of the District. <br /> <br />CLAY TEsrING <br /> <br />The results of the laboratory testing of clay samples collected thus <br />far in the Colorado State University program are outlined in Table II. In <br />examining the results, please keep in mind that they are based upon sampling <br />of a preliminary nature. Complete sampling--especially if concentrated on <br />only the best clay layers--could produce results appreciably different than <br />those found in Table II. <br />The results of the clay testing are discussed in more detail later in <br />this report under DISCUSSION OF INITIAL RESULTS., but because of the <br />samp*g limitations, conclusions regarding acceptability of specific clays <br />I <br />for sealing work are not now possible. This is a question that involves not <br /> <br />1042 <br />
