A review of these curves <br /> <br />indicates that a significant amount of flow is available for <br /> <br />generation during the non-irrigation months of January, <br /> <br />February, March, November and December'. This data indicates <br /> <br />that there is sufficient water in the Gunnison River to <br /> <br />divert 924 cfs during the non-irrigation months.

It is <br /> <br />anticipated that a year-around flow of up to 924 cfs could <br /> <br />increase the flooding potential on the Uncompahgre River <br /> <br />during the high runoff months of May and June. Such <br /> <br />flooding potential will however be significantly decreased <br /> <br />by the completion of the Ridgway Dam in 1987. The operating <br />plan proposed here also anticipates shut down periods of up <br /> <br />to thirty days duration to perfor~ necessary maintenance on <br /> <br />the canal. Such periods are anticipated to occur on a <br /> <br />schedule of every several years, as required by the Bureau <br /> <br />of Reclamation to maintain the primary irrigation function <br /> <br />of the tanal system. <br /> <br />A- ti <br />
