<br />. <br /> <br />. <br /> <br />. <br /> <br />3 <br /> <br />2.0 CONDITION OF VICTOR DAM NO.2 <br /> <br />Victor Dam No.2 is a 33-foot hig~ earthfi11 dam that was orig- <br />inally constructed in 1898. During the 1960's (approxi8ate), the <br />dam was raised 5 to 8 feet to its present height to increase the <br />water storage capacity of t~e reservoir. The reservoir now has a <br /> <br />storage capacity of about 259 acre-feet. Tl:J.e orio;ina1 dam con- <br />figuration is unknown, but is estimated that the structure had a <br />crest width of 12 feet and upstream and downstream slopes of <br />about 1.75 horizontal to 1 vertical (300). When the dam was <br />raised, it was apparently done by adding fill on the crest and <br />downstream slope. The estimated orio;inal configuration and <br />existing configuration are presented in cross section on <br />Figure 3. Photos of the dam are presented on Figure 4, <br /> <br />In 1976, the State Engineer gave this dam a moderate hazard <br />classification. The hazard rating is based on dam height, storage <br />capacity, number of people that have to be evacuated in case of a <br />dam break, and potential for downstream damage. The moderate <br />hazard ranking is the second highest out of four categories, <br /> <br />Except as noted, the following description refers to the dam as <br />observed dur.i.ng our site inspection on July 10, 19-34, The 'l/a t er <br />level in the reservoir at the time of the inspection was at <br />22..5 feet, <l.S 'nep_Bured from the gage located at left side of the <br />outlet tower, This corresponds to a water level 8.5 feet below <br />the crest of the dam which satisfies the order of the State <br /> <br />Engineer. <br /> <br />A 12 foot wide spillway is excavated into natural materials at <br />the south end (left abutment) of the dam (Figures 5 and 6). <br />After lowering the spillway in the fall of 1934, the spillway now <br />provides the structure with about 8 feet of freeboard.
