The maxImum Inflow of 13,060 cf. <br />occurred on July 1. The minImum relea88 for <br />power generation Is 500 cfs; the maximum <br />relea.e through the powerplantl., ,750 cf. at <br />rated heed. A total of 1,629,000 acre-teet was <br />releesed from the reservoir with 796,000 <br />Bcre.-feel bypassIng the powerplant. <br /> <br /> <br />Self propelled .prlnkler .yatem, Yuma M.,.. <br /> <br />Wata, Vea, 1983 <br />At the beginning of water year 1983, tM <br />etevat\'3'i'\ a' F()n~ene\\e ReservoIr was 6504 <br />feet with e content of 328,000 acre-feet. <br />Releases from the reservoir, assuming <br />average runoff conditions, will be scheduled <br />to draw the water down to 6479 teet pr\or \0 <br />the spring runoll. <br /> <br />During October, the reservoir was drawn <br />down 131eot In order to In....estlgate the cause <br />of Increased seepage a!ong the left abutment. <br />A drilling and te.t program I. being conducted <br />to determine whether remedial action should <br />be taken. <br /> <br />The maximum release from Fontanelle <br />ReservoIr Is dependent primarily on the <br />magnItude ollhelnllow, It the Inllow Is In the <br />upper quartile, peak outflow I. expecled to be <br />les. than 10,000 cfs, With an averagelnllow, <br />the anticipated peek outflow I. la.. lhen 5,000 <br />ets.
