<br />r:~) <br /> <br />N <br />co <br />1',:- <br />o <br /> <br />B. Summer storage in John lIartin Reservoir shall commence <br />on April 1st of each year and continue to and include the <br />next succeeding October 31st. During said period, except <br />when Colorado water users are operating under decreed <br />priorities -----, all water entering said reservoir up to <br />the limit of the then available conservation capacity shall <br />be stored: Provided, that Colorado may demand releases of <br />water equivalent to the river flow up to 500 c.f.s., and <br />Kansas may demand releases of water equivalent to that <br />portion of the river flow between 500 c.f.s. and 750 c.f.s., <br />irrespective of releases demanded by Colorado. <br /> <br />C. ---- Unless increases to meet extraordinary conditions <br />are authorized by the Administration, separate releases <br />of stored water to Colorado shall not exceed 750 c.f.s., <br />separate releases of stored water to Kansas. shall not exceed <br />500 c. f. s., and concurrent releases of stored water shall <br />not exceed a total of 1,250 c.f.s.: Provided, that when <br />water stored in the conservation pool is reduced to a quantity <br />less .than 20,000 acre-feet, separate releases of stored water <br />to Colorado shall not exceed 600 c.f.s., separate releases <br />of stored water to Kansas shall not exceed 400 c.f.s.. and <br />concurrent releases of stored water shall not exceed 1,000 <br />c. f.s. <br /> <br />12. Reservoir stage. Plate 2 shows the stage of thq reservoir at the <br /> <br />end of each month during the period from 1 January 1943 to March 1972. The <br /> <br />maximum stage during each calendar year is also indicated. The reservoir <br /> <br />is considered empty when .the water surface is at elevation 3,764.25,. the <br /> <br />invert of the sluicing conduits. The highest reservoir stage recorded <br /> <br />during the entire period of operation was elevation 3,856.16 feet. This <br /> <br />occurred on 25 August 1965 and was 5.16 feet above the hottom of the flood <br /> <br />control pool, elevation 3,851. <br /> <br />13. Operation of reservoir. John Martin Reservoir has been officially <br /> <br />in operation since 11 ~larch .1943; however, storage of water actually began <br /> <br />in December 1942. Even before December 1942, there were significant changes <br /> <br />in the original capacity caused hy a flood of large magnitude that occurred <br /> <br />6 <br />
