Trout Valley Ranch SWSP June 19, 2017 Plan ID 5900 Page 3 of 7 • Distance from the pond centroid to the river (X) = 3,400 feet • Specific yield (S) = 0.16 • Transmissivity (T) = 58,900 gallons per day per foot Lagged depletions resulting from use of ground water at the site are estimated to total 7.62 acre-feet from the start of this plan period through October 31, 2017; 20.09 acre-feet for the period of November 1, 2017 through October 31, 2018; and 13.03 acre-feet for the period of November 1, 2018 through May 31, 2019. A monthly breakdown of projected replacements is shown in the attached Table 5. This office was unable to replicate the AWAS results obtained by the Applicant using the provided aquifer parameters and consumptive use. In addition, a review by the Division of Water Resources’ hydrogeological staff indicated that a transmissivity of 42,400 gallons per day per foot may be more appropriate for the area. However, the replacements proposed to be provided by the Applicant are greater than the depletions calculated by this office, and therefore the Applicant’s values will be accepted for the purposes of this SWSP. Replacements The Applicant has entered into an agreement with North Fork Associates, LLC and Mountain Mutual Reservoir Company for the lease of an annual amount of 28.0 acre-feet of replacement water, with the option of leasing an additional 10.0 acre-feet (copy attached). The lease is currently valid through October 31, 2017. The Applicant has the option of leasing replacement water for two additional one-year periods. This SWSP shall expire on October 31, 2017 unless an extension of the lease is obtained and provided to this office. The water rights available pursuant to the lease include: 1) fully consumable water attributable to the Slaght Ditch (WDID 8000660) and Mack Ditch No. 2 (WDID 8000661) water rights as quantified and decreed in case no. 2003CW238 (located on the North Fork of the South Platte River); 2) fully consumable water attributable to the Nickerson No. 2 Ditch (WDID 8000797), Parmalee No. 1 Ditch (WDID 8000790), and Carruthers No. 2 Ditch (WDID 8000789) water rights as quantified and decreed in case no. 2000CW174 and all located on Deer Creek, a tributary to the North Fork of the South Platte River; 3) fully consumable water attributable to the Guiraud 3T Ditch (WDID 2300679), located on the Middle Fork of the South Platte River downstream of the point of depletion, previously quantified and changed in various decrees; and 4) fully consumable water stored in Lower Sacramento Creek Reservoir No. 1 (WDID 2304494) located on Sacramento Creek, upstream of the point of diversion in Section 32, T9S, R77W, pursuant to the decree in case no. W-7741-74. The water quantified and decreed in case nos. 2000CW174 and 2003CW238 may also be stored in Maddox Reservoir (WDID 8003929), located on the North Fork of the South Platte River, and released from Maddox Reservoir for use in this SWSP. Reservoir accounting is required for the proper administration of such water diverted to storage and stored for later release. Replacement water will be delivered at the headgates of the referenced ditches and/or the outlets of the referenced reservoirs. To the extent that the decreed place of use of any of the leased water rights conflict with the proposed place of use, this SWSP constitutes approval of a change of place of use of the leased water to allow for use at the location of the Trout Valley Pit or upstream of the calling right.
