The table shows that while the average flow for no month equals 

 one-half of the sum of the decreed rights, at times during the months 

 of April, May, June, and July there has been more than enough 

 water to supply all decreed rights, leaving some water to flow down to 

 lower ditches. On- the other hand, the table shows that there have 

 been times in each month when the flow of the stream does not equal 

 one-twentieth of the decreed rights in this one section. Some of the 

 ditches farther down on the river have decreed rights which must be 

 supplied from this flow, but the river receives some tributaries below, 

 so that the table does not present the exact situation, although it gives 

 a good illustration of the general condition on the South Platte. At 

 times there is more water than all the ditches can divert; at other 

 times only a few can be supplied, with the average far below the sum 

 of the rights. 



The following table gives similar facts for the Cache la Poudre. 

 The record extends from 1894 to 1903, inclusive. The sum of decreed 

 rights to the river below the point of measurement, where the river 

 leaves the mountains about 12 miles above F'ort Collins, is 3,988 cubic 

 feet per second.
