RESPONSE BY DIVISION ENGINEER TO CONSULTATION BY REFEREE
COMMENTS:
This application seeks to adjudicate an underground water right and plan for augmentation for a gravel
mining operation on 9.9 acres near Gunnison, Colorado. The underground water right is referred to as
Seahorse Pond Well which is a gravel pit. Source of supply to this structure will be intercepted ground
water tributary to Tomichi Creek. The pond will have a 7.3 acre surface area and is anticipated to have a
30 foot depth. Location of the pond is within 100 lineal feet of Tomichi Creek; therefore, the impact to the
stream is considered instantaneous.
.a
Depletions to the Tomichi Creek and-.Gunnison River systems will accrue from pond evaporation (17.20
AF), water used in gravel washing (0.22 AF), and water removed from the site in the form of moisture
content in the gravel (2.66 AF) for a total of 20.08 AF/yr. It is anticipated the mine will be in operation for
four years. Upon completion of mining activity, the annual consumptive use will be limited to annual
evaporation losses of 17.20 AF.
To offset the depletion, applicant claims dry-up credits for irrigated ground under the Griffing No. I Ditch.
Applicantelaims 6.0 acres as historically irrigated under the Griffin No. I Ditch and an additional 3.4 acres
that was sub-irrigated. It is appropriate to recognize only the amount actually served by the Ditch, or 6.0
acres. Use of the Blaney-Criddle method for irrigated haylands at this elevation and geographic location
