KANSAS UNI\ERSITV ()UARTERLV, 



A few measurements of the flow of the Huerfano and Purgatoire 

 have been made, but not enough to be of much value. They show 

 this, however, that the minimum flow is very small, and the flood 



flow large and sudden, due to cloud-bursts and the sudden melting 

 of snow. The same is true of the other tributaries which we have 

 mentioned. 



From this table we see that the discharge of the river at any point 

 varies much from year to year; thus the mean discharge at Canon 

 City in 1891 was 2^2 times that at the same place in 1S89. 



Table V, which we have compiled from the report of the State 

 Engineer of Colorado for 1889-90, gives data for eleven water dis- 

 tricts of the Arkansas and its tributaries. Column one gives the 

 number of the district, two the name of the principal stream in the 

 district — from which the location of the district may be seen, 

 three the number of canals in the district, four the decreed capac- 

 ity of the canals, five the computed capacity in case a court decree 

 has not been obtained. 



Five of the canals in Dist. No. 10, constructed prior to 1888, have 

 a capacity of 71 cu. ft. per sec; 142 in Dist. No. 11, constructed 

 prior to 1888 have a capacity of 581 cu. ft. per sec. ; 121 in Dist. 

 No. 12 were constructed prior to 1888. 



From this table we see that the capacity of the canals in these dis- 

 tricts is at least 41,743 cu. ft. per sec. This is more than five times
