<br />Near Alfalfa <br />At Nine Mile Dam <br />At Highland Dam <br />Near La Junta <br />At the mouth <br /> <br />1905-1907; 192.5-l928. <br />192.5-l937. <br />1931-l937. <br />l898. <br />l889; 1909j 1923-l93l. <br /> <br /> <br />W18C4 <br /> <br />. <br /> <br />other records of the Purgatoire River flow are as follows: <br /> <br />Automatic gages have been used since 1922 in obtaining <br /> <br />daily canal diversions from the Purgatoire River. Until 1929 <br /> <br />the records are fragmentary but since that date they are practically <br /> <br />complete. <br /> <br />Table 6 shows the annual discharge of the Purgatoire River <br /> <br />at Trinidad, at Nine Mile Dam, at Highland Dam, and at the mouth, <br /> <br />with the annual diVersion from the river between the dam site and <br /> <br />.' <br /> <br />Nine Mile Dam. Diversions in e~cess of the annual runoff at Trinidad <br /> <br />are due to flood flows and return flow which enter the stream <br /> <br />below the gage. <br /> <br />Regulated Flow <br /> <br />Since the project plan contemplates the regulation of <br /> <br />flood flows only, the reservoir would have little effect on normal <br /> <br />stream flow. Storage capacity would be seriously depleted by silt <br /> <br />if water is retained in storage. It is considered best to provide <br /> <br />uncontrolled outlets to regulate flood discharges to a point where <br /> <br />they can be utilized fully by existing canals near Trinidad. Table <br /> <br />5 shows 300 second-feet of early direct rights ahead of lower valley <br /> <br />. <br /> <br />26 <br />
