Prepare State legislation which would modify existing statutes to permit the use of water <br />conserved through structural improvements and the corresponding management <br />possibilities for instream flow enhancement while maintaining the original appropriation <br />date of the underlying decree. <br /> <br />2. Maintain historic diversion patterns and change the point of some of the administrative <br />spills to the inlet of tunnel number 3. (Tunnel number 3 is located several miles <br />downstream from the GVP Diversion Dam and an administrative spill at this point would <br />return the water to the river between the GVWUA Diversion Dam and the beginning of <br />the I5-Mile Reach.) During periods of high irrigation demand it is anticipated that little <br />or no water would be available at tunnel number 3. This alternative may not require a" j <br />change in the 730 cfs irrigation water right of the USAlGVWUA. < <br /> <br />3.
