FAX NO. : 970 641 7606 Aug. 21 2002 03:55PM P9 TABLE 1 (continued) PROCEDURE TO ESTIMATE DEPLETIONS AND DIVERSIONS Code Structure T o f Use Procedure used to Estimate Diversions and Depletions 1 2 3 4 LC Well and Lake City DWR recorded d"nrersion at structure 621022 equal 465 ac-ft and estimated depletions Ditch equal 167 ac -ft (38% depletion factor from StateCU). No DWR diversion records for Structure 625=. Diversions at structure 625000 estimated as 45 BGft (= people x 120 gpod x 305 days, population from 1995 census, 120 gpcd from 3taleCU) and depletions estimated to be 16 ao-ft (45xU.36, 36% from StateCU). Meek Ditch Transbasin Diverts water out of Crystal creek into the Smith Fork Basin. All of the diversions are den letions relative to the As inall Unit. Ot Non - Other Diversions and depletions are estimated at 0.44 ar ft which is the value estimated by the Reservoirs Division 4 Engineer for other water rights when no additional information is available. Sri Pipeline Snowmaking Created Butte Mountain Resort (CBMR) snowmaking wafer right. Diversions of 216 ac-ft From CBMR records. Depletions estimated to be 20 based on other water right transfers involving snowmaking water rights St Well and Stock Diversion and depletions equal .40 ac- fUwater right based on estimated deve loped by the Springs Division 4 office. This is equal to 100 cattle using 8 gallons/head/day for 163 days. StsteCU1 Diversion Irrigation with Uscd if the DWR determined via satellite imag55 that irrigated acreage was associated Structure identified irrigated with this structure_ The DWR program STATECU was utilized to estimate the diversions acreage and depletions. For further documentation of the StatraCU program eoa `StateCU Documentation - StateCU Interface Version 4 - Statem FORTRAN Version 10, December 2000' available on the COSS website (address as of Oct. 1. 2001 httw/Yedss.state.co.us). 5tateCU2 Diversion Irrigation with Usea if DWR determined via satellite Images that Irrigated acreage was assoeialed with Structure identified irrigated this structure. The DWR program 3TATECU was utilized to estimate the diversions and acreage and mere dap6vat7ons at the struolura The diwersiorm and depletions from StsteCU were then than one water right divided between the water rights using the decrees amounk on a pro-nda basis. For junior to the Aspinall further documentation of the SWeCU program see "StateCU Documentation - StateCU Unit water rights Interface Version 4 - StateCU FORTRAN Version 10. December 2000" available on the CDSS website (address as of Oct. 1, 2001 httpJ /cdss.state.co.us). StsteCU3 Spring Irrigation with Used if DWR dete nlned vier satellite images that irrigated acreage was associated with identified irrigated this structure. The DWR program STATECU was utilized to estimate the diversions and acreage depletions at the structure, The dluerslons and depletions from StatQCU were quantified in the "Other" category for all diversion structures that are springs. For further documentation of the StateCU program see "StdeCU Documentation - StateCU Interface Version 4 - StateCU FORTRAN Version 10, December 2000" available on the CDSS webs$e (address as of Oct. 1, 2001 http: /Icdss_statacaus)_ To 2nd Reservoir Taylor Park 2nd fill The diversions asaaci sled with the Taylor Park 2nd 1511 are 106,230 ao-ft as stated in the Division 4 accounting sheets for Taylor Park Reservoir. The depletions. aRSoeia15ad With the Taylor Park 2nd fill are the reservoir evaporation losses of 2.086 ac -ft as shown in Division 4 accounting. One of the decreed uses for the Taylor Park 2nd fill is irrigation. Because the Division Engineer has reported that he does not consider that a call from the Gunnison Tunnel was placed this year, we have not made calculations for the supplesrtev5t irrigation diversion allowed under tree refill decree. Zero All Fire, fishery. power Depletions and consumptive uRa ossecivtod with these uses are estimated to to zero ao- generation, wildlife, ft. and recreation Note: Some Water rights have multiple deeonxd users and therefore may be subject to a combination of method codes (Column 1) to estimate dhprsion andlor depletions (o,g„ Oo-St — water right dcorood for domeStio and stock purpo5e5),
