The crest width <br />is about 12 feet and the dam has a 3:1 (horizontal:vertical) upstream slope and a 2:1 <br />downstream slope. According to available plans, the puddle core had a top width of <br />about 5 feet with 1:20 sideslopes down to natural ground aad a narrow trench core <br />below that level ta bedrock. The dam was appazently built in the 1920s. <br />Beaver Park Water Inc. (Water Company) has a few old photographs that show a sluice <br />in operation and horse drawn equipment being used to construct the dam. The <br />upstream slope was reportedIy covered by 9 inches of hand-placed riprap. In about 19$1, <br />the reservoir was drawn down far replacement of the gate operator with a hydraulic gate <br />operator at the crest of the dam. Some photographs of the dam during the drawdawn <br />in 1981 were available, showing the upstream slope to be irregularly shaped with <br />undulations parallel to the upstream face of the dam. <br />Woodward-Clyde Conwltarns <br />233601PR0.1 12-OS-93(E:52am)/RPT 1-1 <br />
