THE IRRIGATION AGE.

Colorado River. 



A telegram received recently by the Reclamation Service 

 from the engineers on the Lower Colorado River in Mexico, 

 reports the successful closing of the break in the bank. After 

 a mighty struggle with this unruly stream, in which all the 

 energy of 1,000 men, supplied with the equipment of the 

 Southern Pacific Railroad, has been employed for weeks, the 

 Colorado has been controlled and once more is proceeding 

 on its way to the Gulf of California. 



A determined effort is being made to fortify the break by 

 constructing many miles of levees. The problem from now 

 on will be to preserve these levees from destruction during 

 the period of floods. 



Strawberry Valley. 



Authority has been granted the Supervising Engineer of 

 the Strawberry Valley project, Utah, to obtain proposals from 

 as many firms as may be practicable for the machinery required 

 for the power plant to be used in excavating the Strawberry 

 Tunnel. It is estimated that the machinery required will 

 cost approximately $100,000. The general plan which has 

 been worked out by the engineers is to erect a power plant at 

 the point where the Strawberry Valley Tunnel water is 

 dropped into the Salem Canal, utilizing a fall of 120 feet, 

 and the minimum amount of water which flows into Spanish 

 Fork about 60 cubic feet per second. This power is to be 

 utilized for furnishing power to the Strawberry Tunnel until 

 it is finished, and in furnishing light and possibly small 

 quantities of power to the towns in the neighborhood of 

 the power plant which are all within a radius of twelve to 

 fifteen miles. 



The estimates indicate that there will be an excess of 100 

 horse power to dispose of for this purpose. The total power 

 generated and available with this quantity of water and fall 

 will be about 500 electrical horse power, of which probably 

 400 will be required to carry 'on the construction of the 

 Strawberry Valley Tunnel. 



Authority has already been granted for the construction 

 of about three miles of canal which will carry the waters of 

 the Strawberry Tunnel, as well as the waters of Spanish 

 Fork, to the power house. 



As the Hondo Reservoir in New Mexico was not com- 

 pleted in time to receive the full flood discharge of Hondo 

 River, the settlers have requested that the project be not 

 declared open this year, but that the members of the Water 

 Users' Association be permitted to buy such water as may 

 be required ; precedence in purchasing to be given to those 

 whose lands are already in cultivation. In view of the action 

 taken by the Secretary of the Interior in the Carlsbad project, 

 which in many respects involves similar conditions, the 

 Supervising Engineer has been directed to provide for the 

 sale of water to the settlers on the Hondo project for the 

 season of 1907. 



Northwestern contractors are offered an excellent oppor- 

 tunity to bid on government work by the Reclamation 

 Service which is now soliciting proposals for the construction 

 of an earth-filled dam and accessory structures located on 

 Willow Creek, about five miles northwest of Augusta, Mont. 

 This work is in connection with the Sun River project for 

 the irrigation of lands near Great Falls. It involves about 

 7,500 cubic yards of open cut excavation ; 170,000 cubic yards 

 of embankment ; 620 linear feet of lined outlet tunnel, and 130 

 cubic yards of reinforced concrete. Bids will be received 

 until March 15, 1907, at the office of the United States Recla- 

 mation Service, Great Falls, Mont., and particulars may be 

 obtained by addressing the engineer at that place. 



The Secretary of the Interior has granted an extension 

 of time to Orman & Crook, of Pueblo, Colo., for completing 

 the work of Schedule 3, South Canal, Belle Fourche irriga- 

 tion project, South Dakota, to June 1, 1907. 



The delay in the work which made this extension neces- 

 sary was caused by the severity of the weather.

 1 year, and The Primer of Irrigation 



In connection with the construction of the Keno Canal, 

 Klamath irrigation project, the Secretary of the Interior has 

 authorized a portion of the work to be done by force account. 

 The estimated cost of this part of the work is about $19,000, 

 and it is proposed by the Reclamation Service to divide it into 

 small schedules so that local contractors can bid on the work. 

 This has been deemed advisable owing to the necessity for 

 delivering water by October 1, 1907. 



Contractors are asked to bid on the work of excavating 

 the Keno Canal, near Klamath Falls, Klamath irrigation proj- 

 ect, Oregon, involving about 80,000 cubic yards of rock and 

 earth excavation. 



The plans, specifications and forms of proposal may be 

 obtained by application to the Supervising Engineer, United 

 States Reclamation Service, Portland, Ore., or the Project 

 Engineer, Klamath Falls, Ore. 



The Secretary of the Interior is soliciting proposals for 

 the construction of twelve miles of main canal, sixty-seven 

 miles of laterals, seventeen miles of waste water ditches and 

 appurtenant structures in connection with the Sun River 

 irrigation project, near Great Falls, Mont. 



The work involves approximately 481,000 cubic yards of 

 excavation, 1,200 cubic yards of concrete, 900 cubic yards of 

 paving and riprap, 290,000 feet board measure of lumber, the 

 placing of 182,000 pounds of steel, and the furnishing of such 

 other material and the performance of such other work as may 

 be necessary for the completion of the work. 



The bids will be opened at Great Falls, Mont., on April 

 3, 1907. Detailed information may be obtained at the office 

 of the Reclamation Service, Washington, D. C, or from the 

 Project Engineer at Great Falls, Mont. 



The Secretary of the Interior has executed a contract on 

 behalf of the United States with the Expanded Metal and 

 Corrugated Bar Company, of St. Louis, Mo., for furnishing 

 1,800,000 pounds of structural steel for the Tieton irrigation 

 project, Washington. The contracting company agrees to 

 furnish this material for the sum of $38,315.99.

Corbett Tunnel. 



Work on the Corbett Tunnel, which is an important unit 

 of the Shoshone project in Wyoming, progressed satisfactorily 

 during the month of ' December, being only slightly delayed 

 by reason of cold weather, which interfered with the laying 

 of concrete. 



The Government is doing this work by force account and 

 in December excavated 791 linear feet of tunnel, drove 801 

 linear feet of heading and concrete-lined 305 feet of arch and 

 side walls. 



On January 1st the Corbett Tunnel had been driven 9,323 

 feet, of which 3,503 feet are lined. 



On the great Shoshone dam, which is to be the highest in 

 the world, the contractor has not made satisfactory headway. 

 His work during the past month consisted of driving a road 

 tunnel and excavating for temporary flume and spillway. 



The engineers report a great improvement in 'labor con- 

 ditions.
