Seminoe Dam
Seminoe Dam is a concrete thick-arch dam on the North Platte River in the U.S. state of Wyoming. The dam stores water for irrigation and hydroelectricity generation, and is owned and operated by the U.S. Bureau of Reclamation. It is the uppermost dam on the North Platte River and is located directly upstream from the Kortes Dam. It lies in a narrow, isolated canyon formed by the North Platte cutting through the Seminoe Mountains about northeast of Rawlins. The dam forms Seminoe Reservoir, which covers more than when full. Seminoe State Park is adjacent to the reservoir.
==History==
This dam was first proposed in the 1930s as part of the Bureau of Reclamation's Kendrick Project, which would regulate the flow of the North Platte River in order to improve agriculture in the valleys surrounding Casper, Wyoming. Originally known as the Casper-Alcova Project, it was authorized by the National Industrial Recovery Act on June 16, 1933 in response to the Great Depression. The project was renamed the Kendrick Project on August 9, 1937 in honor of Wyoming politician John B. Kendrick.
In 1934, Winston Brothers Company and Associates won the construction contract of Seminoe Dam. Groundbreaking of the damsite was on February 20, 1936 with preliminary blasting and excavations. The diversion tunnel for the North Platte was completed on January 17, 1937 with one fatality, and by May of that year, a cofferdam was completed to a sufficient height to divert the river into the new channel. Concrete pouring began on January 19, 1938 and the last bucket was emptied on December 21, 1938; water storage began in April 2, 1939 when the outlet tunnels were closed. The dam's power station was finished and the entire project was declared operational on August 3, 1939. A total of two deaths and several serious injuries resulted from the construction, and a pair of active faults that cut across the canyon near the dam site had to be excavated and filled in.〔
When the project was first completed, it delivered water to just , but has progressed steadily, and by 1980 supplied irrigation water to in the Casper valley.〔
