THE IRRIGATION AGE. 



NOTES. 



I 



The Secretary of the Interior recently awarded a 

 contract to Orman & Crook, of Pueblo, Colo., for the 

 construction of the Belle Fourche, S. D., dam and 

 distribution canals. The contract calls for the con- 

 struction of an earthen dam and appurtenances and 

 seventeen and a half miles of canals, involving about 

 2,600,000 cubic yards of earth work, 3,000 cubic yards 

 of rock excavation, 24,000 cubic yards of concrete ma- 

 sonry, and 45,000 pounds of steel and cast iron. 



The dam when completed will be one of the largest 

 earth embankments in the United States. It will be 

 100 feet high in the highest place, one mile long on top, 

 tweriy feet wide on top, with one and a half to one 

 water slope, which will be completely paved with stone 

 to a depth of eighteen inches. The conduit or controll- 

 ing gates are to be placed in a concrete well located in 

 the center of the fill, connecting with the reservoir and 

 the distributing canal by a three-inch concrete conduit 

 of sufficient capacity to fill the canal when the reservoir 

 is low. -In this well three steel gates will control the 

 outflow. When the reservoir created by this dam is full 

 the area of the water surface will be nearly 9,000 acres, 

 and the water will be sixty feet deep. 



The canals provided for in this contract are for 

 both sides of the Belle Fourche River. The north side 

 canal, to provide water for 60,000 acres, will have at 

 its head a bottom width of twenty-six feet and will 

 carry a depth of water of seven feet, with a grade 1.056 

 feet per mile. The south side canal will irrigate 4,000 

 acres on the north side of the river, emptying a quan- 

 tity of stored water into the river which will be diverted 

 into a continuation of the canal on the south side of 

 the river and made to irrigate 20.000 acres of the 

 first-class lands in the vicinity of Vale and Empire. 

 The first section of this canal will be sixteen feet wide 

 on the bottom, carry a depth of water of five feet, giv- 

 ing it a capacity of 243 second feet. 



The successful bid on the dam was $879,164; on 

 the north side canal $71,129.75 ; and on the south side 

 canal, $53,005.5.0. According to the contract the dam 

 must be completed by September 1, 1909; the north 

 side canal by May 1, 1907; and the south side canal 

 by September 1, 1906. It is specified that as work 

 upon the dam progresses the Reclamation Service has 

 a right to store water behind it to such height as the 

 engineer may determine to be safe. In case 'the work 

 on any schedule is not completed on the date required, 

 a deduction of $50 per day will be made from the 

 amount due on the contract for such schedule for each 

 and every day the work remains uncompleted.
