American Falls Dam - Located on the Snake River near the city of American Falls, Idaho, this project was completed in 1927. It is a gravity dam and is 94 feet high and 5, 227 feet long. The volume content of the dam is 313,600 cubic yards. The reservoir name is American Falls also and its capacity is 1,700,000 acre-feet. The purpose for construction of the dam was irrigation, power, flood contral and water supply. The owner of the project is the U. S. Bureau of Reclamation and the project was engineered by them also. Approximate cost of the project was $3, 040, 000. 2. Guernsey Dam - Forerunning the large joint ventures of groups of contractors that were to come in the next decade, Utah teamed up with Morris on-Knudsen Co., Inc. of Boise, Idaho. First of the joint dam-building ventures of the Utah Construction Company and Morris on-Knudsen was the 560 foot long earth filled Guernsey Dam built across the North Platt River in eastern Wyoming. The dam and powerhouse were erected for the Bureau of Reclamation as a power, irrigation-storage, and diversion unit of the North Platt Project. Guernsey was the last of larger Utah dams built before the advent of gasoline- - powered equipment. Steam power and railroad equipment were used throughout its construction. Usually in dam construction the work area is unwatered by diverting the river, then kept dry while the dam builders excavate to solid rock. But at Guernsey, the foundation area was never completely unwatered |
