Pleasant Valley and Lake Canal Company (ID 0300910) <br />Note: The list consists of all mutual ditch companies having direct flow rights from the Cache la Poudre River. <br />The 66 water rights associated with the ditch companies in the Poudre Plan have priority dates <br />ranging from 6/1/1861 to 9/28/1914 and a total decreed flow rate of about 4,019 cfs. The Poudre <br />Plan allows the wells to divert as alternate points of diversion the unused portion, up to the full <br />entitlement, of the in priority assigned rights in addition to their original in priority decreed <br />ground water rights. None of the wells were historically metered or have calibrated electric <br />coefficients; therefore, no actual pump records are available. <br />Recommendations <br />Recommendations for representing the Cache la Poudre Water Users Plan in the initial <br />development of the SPDSS StateMod Water Resources Planning Model input files are presented <br />below based on review of the decree and interviews with Water Commissioner George Varra. <br />Augmentation Plan Demands <br />To represent pumping for the entire SPDSS study period (1950 to present), well pumping to <br />supply irrigated lands should be estimated by the consumptive use algorithm in StateCU and <br />StateMod, to meet the irrigation water requirement less simulated surface water deliveries. <br />Lagged depletions should be accounted in one Poudre Plan structure (ID 0303336) on the Cache <br />la Poudre River above the confluence with the South Platte River. <br />Augmentation Plan Supplies <br />No recharge water rights are used as part of the Poudre Plan since all wells are operating as <br />alternate points to surface water rights. The structures related to the Poudre Plan recommended <br />for inclusion in the SPDSS model are summarized in. Augmentation supplies are as follows: <br />Table 2. <br />Table 2 <br />Poudre Plan Structures (Plan ID 0303336) <br />Com onent WDID Comment <br />Augmentation Plan 0303336 Plan ID used to track total pumping and depletions. <br />Augmentation Plan Operations <br />Operation of alternate point diversions at the wells in the plan could be addressed similar to the <br />StateMod Type 24 rule (StateMod Version 11_50) currently used to simulate diversions at <br />alternate points. <br />A-32 of A-106 <br />
