right. The crest of the embankment is at an elevation of 6880 feet, and the <br />principal spillway elevation is 6872 feet. <br />A drilling program was recommended after site selection was made. Ground <br />Engineering Consultants, Inc. contracted for drilling and soils testing, and <br />completed the drilling program in November 1991. Drill holes A through N were <br />completed along the embankment centerline (OH-C, -D, -E, and -F), slightly <br />upstream from the left abutment (DH-A), upstream from the right abutment (DH-M, <br />and -N), slightly downstream from the embankment centerline (DH-G, -H, and -B), <br />and in the pond area and vicinity (DH-I, -J, and -K, and -L). These holes are <br />shown on Figure 1. Two additional holes were drilled on the haul road <br />alignment at Sta. 52+65 (DH-P) and at Sta. 53+90 (DH-Q) to determine the <br />characteristics of materials for possible use in the embankment construction. <br />A total of 16 holes was drilled ranging from 10.5 feet to 54.0 feet in <br />depth, and an aggregate of 460 feet of drilling was completed using a <br />continuous-flight auger. DH-0 was planned but could not be drilled because of <br />adverse surface conditions. <br />The bedrock configuration is well defined in Figure 2. Although the dam <br />will not be anchored in bedrock, it is in geologically acceptable materials and <br />it is anticipated that analysis of samples taken in the drilling program will <br />bear this out and indicate that usable materials for embankment construction <br />are available from the pond area, and from elsewhere if needed. <br />5.3 Stockpile Areas <br />Five stockpiles in four general areas were reviewed with respect to <br />stability. This review was not originally scheduled; therefore, specific <br />attention was not given to these areas during in the field work. The review, <br />however, was feasible because of general information collected in the field, <br />and fur•ther• photogeologic evaluation. All of the areas designated for review <br />16 <br />
