warranty at the site. With each successive SWSP renewal request, the Applicant shall demonstrate
continued diligence in this effort, including maintaining satisfactory status in obtaining proper bonds
through DRMS.
Conditions of Approval
This substitute water supply plan is hereby approved in accordance with section 37-90-137(11), C.R.S. and
subject to the following conditions:
1. This SWSP is approved with the effective date of November 1, 2023 and shall be valid through
October 31, 2024 unless otherwise revoked or superseded by a decree. If this plan is not decreed
in water court by the SWSP expiration date, a renewal request must be submitted to this office with
the statutory fee of$257 no later than September 15, 2024. If a renewal request is received after
the expiration date of this plan, it will be considered a request for a new SWSP and a filing fee
of$1,593 will be required.
2. The total surface area of the groundwater exposed at the site must not exceed 0.91 acres
resulting in annual evaporative losses of 2.60 acre-feet during the approval period of this SWSP.
3. This SWSP does not permit any water use for dust control, aggregate production, or any other
purpose, other than evaporation.
4. Total consumption at the site must not exceed the aforementioned amounts unless an amendment
is made to this plan.
5. Well permit no. 57723-F is in good standing for the current use and exposed surface area at the site
in accordance with sections 37-90-137(2) and (11), C.R.S.
6. Approval of this plan is for the purposes as stated herein. Any additional uses of this water must
first be approved by this office.
7. All releases of replacement water must be sufficient to cover all out-of-priority depletions in time,
place, and amount and should be made on a daily basis. The release of monthly replacement water
may be aggregated in a single release to maximize beneficial use at the direction and approval of
the Water Commissioner.
8. The Applicant must replace all out-of-priority depletions resulting from operation underthis SWSP,
including those lagged depletions that occur to the stream after the expiration date of this SWSP.
9. As part of any renewal of this SWSP the Applicant must specify the proposed replacement source
that will be used to replace all lagged depletions that result from operation under the SWSP,
including those that extend beyond the approval period of the SWSP. If the intent is to obtain a
short-term lease for such future replacement water, an executed lease for depletions that extend
beyond the SWSP approval period is not required; however the Applicant must demonstrate that
there is a reasonable likelihood that such a lease could be obtained.
10. Conveyance loss for delivery of augmentation water to the South Platte River is subject to
assessment and modification as determined by the Division Engineer. Currently, conveyance losses
are being assessed at 5.39% (0.5% per mile) during the irrigation season (April through October) and
2.7% (0.25% per mile) during the non-irrigation season (November through March).
11. The Applicant shall provide daily accounting (including, but not limited to depletions, replacement
sources, and river calls) on a monthly basis. The accounting must be uploaded to the CDSS Online
