Table 2 <br />Lower Platte & Beaver Augmentation Plan Structures (Plan ID 0102535) <br />Component WDID Comment <br /> 0102535_1 Plan ID (by reach) used to track total pumping, depletions, <br />Augmentation Plan 0102535 <br />2 and water supplies. Water supplies include natural stream <br /> _ <br />0102535_3 flow if the downstream call is junior or no call is active. <br />Recharge Site 0100518 Rch Reservoir ID used to store diversions to a Recharge site. <br /> 0102535 P1R1 Plan IDs (by reach) used to track lagged accretions from <br />Recharge Seepage 0102535 P1R2 Recharge site seepage to locations where plan is <br /> 0102535 P1R3 administered (see Augmentation Plan Demands). <br /> 0102535 P1C1 Plan IDs (by reach) used to track lagged accretions from <br />Canal Seepage 0102535 P1C2 canal seepage to locations where plan is administered (see <br /> 0102535 P1C3 Augmentation Plan Demands). <br />Reservoir* Various Reservoir ID used to replace depletions by a storage <br /> release directly to river. <br />Augmentation Well* * Various Well ID used to track accretions from a ground water <br /> diversion directly to river. <br />* Gebauer Recharge site included in the pending 03CW443 application. <br />* * Ditch company representatives indicated augmentation well included in pending Water Court application (Case No. <br />03CW443). No augmentation wells associated with Lower Platte & Beaver augmentation plan ID in HydroBase (Version <br />20060816). <br />Lagged accretions to the South Platte River from recharge diversions are returned to the river <br />based on return flow factors and locations defined in StateMod input files. Lagged accretions <br />should be accounted in recharge accretions structures based on source of seepage water: <br />• Recharge site seepage (IDs 0102535_P1R1, 0102535_P1R2, and 0102535_P1R3) <br />• Canal seepage (IDs 0102535_P1C1, 0102535_P1C2, and 0102535_P1C1) <br />Canal seepage should be accounted based on simulated ditch losses from all diversions to <br />recharge when no other supplies (e.g., irrigation) are being run in the ditch. Canal seepage and <br />recharge seepage associated with the Lower Platte & Beaver plan should be assigned to the <br />various administration reaches based on spatial location. <br />One recharge water right is used to divert water from the South Platte River into the ditch and <br />multiple recharge sites (pits) off the Lower Platte & Beaver Canal. The capacity of the ditch and <br />number and capacities of the pits able to store recharge water is unknown; therefore, the demand <br />for the recharge water rights should be modeled at one recharge site located at the end of the <br />Lower Platte & Beaver Canal, as summarized in Table 3. <br />Table 3 <br />Lower Platte & Beaver Augmentation Plan Recharge Water Rights <br />i <br />Di <br />h <br />C Recharge Site at end of Capacity / Supply <br />arr <br />er <br />tc Ditch Target Amount Admin.
