AND THEIR RELATION TO IRRIGATION. 
27 
Taking all these sources into consideration, it seems 
safe to conclude that while the supply will most likely 
exceed 600 feet per second, it is not apt to reach 1,500. 
The average flow of the present wells in the valley 
may be taken as twenty-five gallons per minute, whence 
their combined flow is in the neighborhood of 110 cubic 
feet per second. 
It is probable, therefore, that the number of wells 
may be increased until the flow is six times as great, but 
not likely that it may become fifteen times as great. 
Assuming the smaller amount as the amount of 
water eventually available, if it were all used in irriga¬ 
tion, it might irrigate, at seventy acres to the second foot, 
some 42,000 acres ; and, if used with storage, three or 
four times as much. 
ARTESIAN WELLS ON THE PLAINS. 
A word may be said in answer to the numerous in¬ 
quiries which come as to the probability of finding arte¬ 
sian water on the plains of Colorado. We all know 
that it would be of great importance if it could be found 
even in comparatively limited quantities. Attempts have 
been made at several places, widely scattered, to consider¬ 
able depths. At Fort Lyon a flow of three gallons per 
hour was met at 430 feet, but no other to the depth of 700 
feet, where the boring was stopped. At Akron, no flowing 
water was found. Water from a depth of 1,155 feet came 
within fifty-five feet of the surface. At Otis/not far east 
of Akron, a boring was made to the depth of 2,400 feet, 
but no water of any kind is reported. At Kit Carson no 
water was found within 1,500 feet. A well was sunk at 
Sheridan Lake, no water; also at Calhan, with the same 
result. At Cheyenne Wells two have been sunk, but 
without finding flowing water, though one is pumped for
