1. Adapted from EVAPOTRANSPIRATION AND AGRONOMIC RESPONSES IN
FORMERLY IRRIGATED MOUNTAIN MEADOWS, South Park, Colorado, March 1, 1990;
Revised September 1, 1991
12. The approval of this substitute water supply plan does not relieve the Applicant and /or
landowner of the requirement to obtain a Water Court decree approving a permanent
plan for augmentation or mitigation to ensure the permanent replacement of all
depletions, including long -term evaporation losses and lagged depletions after gravel
mining operations have ceased. If reclamation of the mine site will produce a permanent
water surface exposing groundwater to evaporation, an application for a plan for
augmentation must be filed with the Division 1 Water Court at least three (3) years prior
to the completion of mining to include, but not be limited to, long -term evaporation losses
and lagged depletions. If a lined pond results after reclamation, replacement of lagged
depletions shall continue until there is no longer an effect on stream flow.
13. Reclamation of the North Tower Pit produced a permanent water surface exposing
groundwater to evaporation, therefore an application for a plan for augmentation was
filed with the Division 1 Water Court in Case No. 1990CW39. The approval of this plan
does not imply a position by our office on any litigation associated with case no.
1990CW39 or any other case. If a renewal of this SWSP is required (that includes
the North Tower Pit) the Applicant must include information that describes what
steps they have taken towards obtaining a final decree in case no. 1990CW39, to
assure that the court application continues to progress through the court process.
14. This substitute water supply plan may be revoked or modified at any time should it be
determined that injury to other vested water rights has or will occur as a result of this
plan. Should this substitute water supply plan expire without renewal or be revoked prior
to adjudication of a permanent plan for augmentation, all excavation of product from
below the water table, and all other use of water at the pit, must cease immediately.
15. In accordance with amendments to §25 -8- 202(7), C.R.S., and "Senate Bill 89 -181 Rules
and Regulations" adopted on February 4, 1992, the State Engineer shall determine
whether the substitute supply is of a quality to meet requirements of use to senior
appropriators. As such, water quality data or analysis may be requested at any time to
determine if the water quality is appropriate for downstream water users.
16. The decision of the state engineer shall have no precedential or evidentiary force, shall
not create any presumptions, shift the burden of proof, or serve as a defense in any
pending water court case or any other legal action that may be initiated concerning this
plan. This decision shall not bind the state engineer to act in a similar manner in any
other applications involving other plans, or in any proposed renewal of this plan, and
