A GREAT IRRIGATION DAM 



We now have under construction perhaps the most important dam for irrigation ever built on this 

 continent. It is for the Canadian Pacific Railroad and is a diversion dam on the Bow River about one 

 hundred miles from Calgary. 



That which gives peculiar significance to this piece of hydraulic engineering is the severe flood in 

 connection with the foundations. For at least one month in each year the river attains a maximum flow 

 of 100,000 second feet. We were able to secure a railway 720 ft. long on the crest, on which there is a 

 variable control of 11 ft. by means of Tainter or Stoney gates operated by motors from a bridge crossing 

 the dam. The total head created is 52 feet. Allowing for the contractions due to the roadway piers the 

 flood water at times will reach or exceed a depth of 10 ft. on the rollway. 



This problem would present no difficulties except for the foundations. In that country there is no 

 ledge rock for hundreds of miles in any direction and for an unknown distance vertically downward. The 

 foundations offered are from 3 ft. to 4 ft. of cemented gravel resting on from 15 ft. to 18 ft. of blue clay 

 and this on sand of an unknown depth. To so handle the standing wave that it will not under-scour the 

 foundations of the dam is the engineering problem involved. 



We have built many dams on foundations of this general character, but this example on account 

 of its magnitude is especially noteworthy. 



The purpose of this article is not to enter into an engineering description of this dam but merely to 

 point out its interesting features. Both the engineering and the construction of this important piece of 

 work have been entrusted to. us. Work has already been commenced and will be carried on through- 

 out the winter until the dam is completed.
