<br />BOYSEN UNIT <br /> <br />Description: Boysen Unit consists of a dam, reservoir, and power <br />plant on the Big Horn River 16 miles south of Thermopolis, Wyoming. <br />The dam when completed will be an earthfill type approximately 150 <br />feet high with a crest length of approximately 1,100 feet. The res- <br />ervoir will have a capacity of 1,493,000 acre-feet. A 15,000 kva <br />power plant will be constructed as an integral part of the dam. The <br />reservoir capacity will provide 260,000 acre-feet reserved for silt <br />storage, 673,000 acre-feet of super storage for flood control and <br />560,000 acre-feet for irrigation and power development. <br /> <br />Boysen Dam and Reservoir is a key structure providing for re- <br />regulating the stream to compensate for the several proposed upstream <br />and downstream irrigation developments. The power plant at Boysen <br />is strategically located in the center of a 300-mile transmission net- <br />work between Shoshone Power Plant and the Seminoe Power Plant near <br />Casper. <br /> <br />Construction of Boysen Reservoir necessitates the relocation of <br />13.4 miles of the C. B. & Q Railroad, a section of the C&NW Railroad, <br />and also a portion of U~ S. Highway No. 20. The relocation of the <br />highway was completed November 25, 1947 on a contract awarded on <br />August 29, 1947 for construction of the dam, power plant and reloca- <br />tion of the railroad. This contract was awarded to Morrison-Knudsen <br />for $13,899,999. <br /> <br />The total cost of Boysen Unit is estimated at $29,726,000, The <br />total cost to June 30, 1949 was $16,298,555.
