<br />'7..) <br />'-:J <br />~ <br />o <br />to) <br />~ <br /> <br />29 <br /> <br />and September; and increases occurred during June, <br /> <br />July, and October. <br /> <br />Based on the results of the reservoir operation <br /> <br />simulation that used the maximum release equation, the <br /> <br />following plan for the operation of the irrigation <br /> <br />features of John Martin Reservoir is recommended. <br /> <br />1. During November through March releases at <br /> <br />John Martin Dam should not be allowed. Diversions by <br /> <br />ditches should be limited to the amounts that are <br /> <br />available from return flow and other accretions. <br /> <br />2. Releases can be made during the irrigation <br /> <br />season, as demanded by irrigators in Water District <br /> <br />67, at maximum rates that are computed on a bimonthly <br /> <br />basis from the following equation, which was obtained <br /> <br />from the previous equation after adjusting for the <br /> <br />change in the time periOd and for the change in the <br /> <br />units. <br /> <br />R = 0.9785 (DD) - 71.48 (AVPRCP) - 424 <br /> <br />where R <br /> <br />= maximum release rate in cfs <br /> <br />DD = degree-days during the bimonthly period <br /> <br />AVPRCP = average precipitation during the <br /> <br />bimonthly periOd <br />
