Funding for the project is provided through a loan obtained from the Colorado Water Conservation Board and the Department of Local Affairs. Geotechnical investigations for this study were conducted under a subconsul tant agreement between Greenhorne & O'Mara, Inc., and Golder Associates, Inc., a consulting geotechnical and mining engineering firm. Field survey information for the study was completed by Greenhorne & O'Mara, Inc. Valuable input during the course of this project was provided by Mr. Mickey Groves, Publ ic Works Director and Mr. Edward Erickson, City Administrator, both from the City of Victor. The Project Manager in charge of this project for the Colorado Water Conservation Board is Mr. Frank Akers. Study Background In March 1984, the City of Victor informed the Colorado State Engineer that longitudinal cracking had recently been discovered on the crest of Victor No.2 Dam. On June 7,1984, an inspection of the dam was made by the State Engineer's Office. This inspection resulted in a letter from the State Engineer dated June 22, 1984, which directed the City to restrict the level of water in the reservoir to an elevation approximately 8-feet below the dam's crest. This was recommended as a safety precaution, since the existing emergency spillway for the dam was determined to be hydrologically inadequate to pass the required design flood. Lowering the dam level required that the existing spillway be excavated down 1.5- feet to maintain 8-feet of freeboard. A further recommendation of the State Engineer's Office was that if the City 6
