It is a gravity type dam with a structural height of 454 feet and a crest length of 1,528 feet. The volume content of the dam is 1,357,000 cubic yards. The reservoir's name is Detroit also and has a capacity of 45,000 acre-feet. Purposes for con- struction of the dam were irrigation, power, flood control, navigation and water supply. The installed power capacity is 100,000 kilowatts. The project was engineered by the U. S. Corps of Engineers and is owned by them also. The project was constructed by Consolidated Builders, Inc. --a joint venture composed of Henry J. Kaiser Co., Utah, Shea Co., General Construction Co., Pacific Bridge Co., Walsh Construction Corp. Approximate cost of this project was $25,274,000 and our share was 15%. Coello Dam and Canals - Sometime during the month of July, 1950, the Coello Project was initiated. The project was located in the State of Tolima and consisted of irrigation projects of the Coello River, which is a tributary of the Magdalena River. The owner of the project was a corporation registered in Bogota, Colombia, namely the Caja de Credito Agrario, Industrial y Minero, hereafter referred to as the Caja.

The latter two firms had headquarters at Bogota, Colombia. The contract called for the construction of a dam for diversion from the river fronting Gualandoy, with a concrete embankment 80 meters long; a canal measuring 7 kilometers in length with three tunnels having a capacity of 18 cubic meters per second; a trapezoidal section 6.40 meters wide at the base with a distributing system allowing 142 kilometers of open canal. It was proposed that the foregoing would completely irrigate 15,000 hectares (37,050 U. S. acres) between the towns of Chicoral and E spinal, which are located on the right bank of the Coello River. The above project was authorized by the Colombian National Government through the Cajam which was an autonomour-organization created by Mandate of Law 57 of the year 1931 and the Caja has the power, as per contracts dated November 22, 1947, February 12 and June 25, 1948, entered into with the Colombian National Government, to construct the public work designated under the name of the Coello Project.
