This does not, however, represent the supply for the lands below 

 Saratoga, as below that jDoint the river receives maii}^ tributaries for 

 which no records are available. 



Since 1894 the Wyoming State engineer's office has kept records 

 showing the flow of the North Platte at Douglas, Grin, or (niernsey. 

 Douglas and Grin are not far apart, and Guernsey is about CO miles 

 below Doutjlas. In the table Avhich follows the nieasui-ciiiciits niv 

 averaged as if all were made at the same point. Tt is not believed 

 that the discharge varies enough between these points to introduce 

 aii}^ considerable error. Laramie River and Horse Creek enter the 

 North Platte below Guernsey, but the present and prospective storage 

 of the flow of these streams makes the supply at Guernsey a fair 

 approximation of what is available for future extension of the irri- 

 gated area along the North Platte below that point. Kights belo\\ 

 this point aggregate 11.172.66 cubic feet per second, a little less than 

 three times the average flow of the stream for the irrigation months. 

 This includes rights to water from llie main Platte, since it receives 

 its principal supply from the Nortii Platte.
