Pau i I31RIss August 3, 2021 Page 3 of 5 For the 2021-2022 plan year, the total lagged depletion is 46.76 AF (see attached Table 5a). REPLACEMENTS Deep Cut will utilize a combination of leased water and historical ditch credits to make replacements to the river. A lease dated February 26, 2018 from the City of Aurora was obtained to provide replacement supplies during this SWSP approval period for 35 acre-feet (lease attached). This lease is valid until December 31, 2023, unless terminated by either party. Chris Tomky of Deep Cut is the owner of 17.45 shares of Twin Lakes Reservoir and Canal Company, including Twin Lakes Reservoir storage associated with those shares, and approximately 19.25 acre-feet of associated storage. The water lease allows Chris Tomky to trade with the City of Aurora 35 acre-feet of Twin Lake shares for 35 acre-feet of Aurora's fully consumable water stored in the Colorado Canal System, released from Meredith Reservoir. Catlin Canal shares are dedicated for long-term replacement, but are not intended to be used for the term of this SWSP. Valco owned 2 shares in the Rocky Ford Ditch, which have been transferred to Deep Cut. However, these shares may result in consumptive use credits in excess of what Deep Cut requires for this season. Valco may, with approval from Deep Cut and the Division Engineer, use a portion of those shares as part of its SWSP replacement requirement. The two shares together are expected to yield approximately 25.72 AF/year. CONDITIONS OF APPROVAL I hereby approve the proposed SWSP in accordance with Section 37-90-137(11), C.R.S., subject to the following conditions: 1. This SWSP shall be valid for the period of August 1, 2021 through July 31, 2022 unless otherwise revoked or superseded by decree. If this SWSP will not be made absolute by a water court action by the SWSP expiration date, a renewal request must be submitted to this office and the Division 2 office (please copy Bethany Arnold at Bethany.Arnold(2state.co.us) with the statutory fee per gravel pit (currently $257) by June 1, 2022. 2. No more than 13.2 acres of groundwater may be exposed at the 22 West Pit during this plan year without first obtaining a new SWSP. Documentation of pond sizes may be required by the Division Engineer in the form of an aerial photo evaluation or survey by a Professional Land Surveyor during the term of this SWSP. 3. Subject to approval by the Division Engineer, the Applicant may lease or purchase additional replacement water from the sources approved in this plan. In addition, the Applicant must also provide a copy of a lease/purchase agreement to the State Engineer's Office and the Division Engineer for use of such additional replacement water. 4. Approval of this SWSP is for the purposes stated herein. Additional uses will be allowed only if a new SWSP is approved for those additional uses. The replacement water, which is the subject of this SWSP, cannot be sold or leased to any other entity during the term of this SWSP without prior approval of the Division Engineer.
