For optimum crop production the monthly dis- <br /> <br />tribution of the total diversion requirement through the growing season <br />is estimated as followsl April .27 acre-feet, May .52, June .55, July <br />.53, August .50, September .34, October .19--a total of 2.90 acre-feet <br /> <br />for the growing season. Although the average annual estj~ted diver- <br /> <br />sion requirement and the average annual historical diversions to the pro- <br /> <br />ject area agree very closely in total amount, a study of individual years <br /> <br />indicates a wide variation on a yearly and monthly basis between his tor- <br /> <br />ical diversions and estimated requirements for optimum crop production. <br /> <br />25. Existing storage and regulatory facilities are inadequate for <br /> <br />complete regulation of the available water supply for maximum crop util- <br /> <br />ization. It is apparent that additional storage facilities are essential <br /> <br />in order to accomplish the necessary regulation and permit maximum effec- <br /> <br />tive use of the available water supplies. <br /> <br />26. Water rights. - The water supply studies are based on the re- <br />corded flows of the Purgatoire River at Trinidad, and upstream diversions <br /> <br />are automatically taken into account. No future upstream depletion of <br /> <br />the river which would adversely affect the use of water by the project <br /> <br />area is anticipated. The Model Reservoir and Johns Lake, units of the <br /> <br />Model irrigation system, are the only storage facilities in the project <br />area. They have decreed water rights for the storage of 20,345 acre-feet <br />
