 engineers of Colorado. The measurements in 1903 were made by Mr.

In 1903 measurements were carried on down the river in Nebraska 

 so far as there was any visible flow in the stream. These measure- 

 ments were made by Prof. O. V. P. Stout, of the University of Ne- 

 braska. The first section measured extended from the head of the 

 Western Canal to Ogallala, 26.5 miles, and showed a loss of 74.8G 

 cubic feet per second. The second section extended from Ogallahi to 

 Korty, a distance of 13 miles, and showed a loss of 7.71 cubic feet per 

 second, making a total loss between the head of the Western Canal, 

 which is very near the State line, and Korty, where the river was dry, 

 of 82,57 cubic feet per second, or all the water in the strealn. 



The table given above shows that there is no uniformity in the gain 

 in any section from year to year or in the stream as a whole. The 

 amount of return seepage depends on so many factors which vary 

 from year to year that it is not to be expected that there would be any
