 take it out of the Marias River by a 

 canal to Big Sandy Creek, a tributary 

 of Milk River. 



An examination of the Milk River in 

 Canada to ascertain if the water could 

 be taken out of that river on its course 

 through Canada was made. It was

 One of the most importanf 6 noted - 



the present outlet of St. Mary's Lake, projects, and certainly the mc RIZO NA 

 Tliis dam will have a maximum eleva- 

 tion of 50 feet above the bottom of the 

 river, and will form a reservoir with a 

 >acity of 250,000 acre-feet. 

 The canal to conduct the water from 

 the reservoir to Milk River will be 30 

 feet wide at the bottom and will carry 

 water to a depth of ten feet, and it is 

 supposed that in a canal of these dimen- 

 sions the mean discharge at its head 

 will he 1,380 second feet. From the
