Both outlet pipes are controlled by valves operable from the <br />top of an inlet structure tower constructed from 5-foot diameter reinforced <br />concrete cylinder stacked vertically. The inlet tower is located about 30 feet <br />measured perpendicularly into the reservoir from the crest and located near the <br />center of the dam. A wooden catwalk, which provided access to the inlet structure, <br />is in disrepair and access to the inlet structure was not possible at the time of <br />our site inspection. <br /> <br />An emergency spillway for the dam is located along the left abutment. It is cut <br />into natural materials and is lined with riprap ranging in size from 3-inches to <br />21-inches. The spillway is irregular in shape but has a bottom width of approxi- <br />mately 10 feet and 2H:1V sideslopes. The present day spillway crest is at an <br />elevation of 10,390.5 feet at the control section. The spillway outlets downstream <br />into a natural rock-lined channel. <br /> <br />The reservoir's originally designed storage capacity is unknown. Estimates made <br />by others indicate the storage capacity to be about 210 acre-feet at a spillway <br />crest elevation 10,392 feet. The City of Victor has water rights to store 202.77 <br />ac re- feet. <br /> <br />In 1976 the Colorado State Engineer classified the Victor No.2 Dam as having a <br />moderate hazard potential for damage and/or loss of life in the event of a <br />failure. According to the State Engineer's Criteria, the dam is classified as a <br />small dam. Small dams are defined as greater than 15 feet in height and store <br />more than 30 acre-feet but do not exceed 50-feet in height or 1,000 acre-feet in <br />storage. <br /> <br />In March 1984 the City of Victor informed the Colorado State Engineer that <br />longitudinal cracking had recently been discovered on the crest of the dam. After <br />inspection of the reservoir, the State Engineer ordered the City to lower the <br />spillway crest 1.5 feet and maintain 8 feet of freeboard on the dam. The spillway <br />elevation was lowered in the fall of 1984 as directed by the State Engineer. At <br />the present spillway crest elevation of 10,390.5 feet the reservoir has a storage <br />capacity of approximately 180 acre-feet. <br /> <br />11 <br />
