Green River Basin Advisory Group
Kemmerer High School Auditorium, Kemmerer WY
September 12, 2000
Facilitator Joe Lord welcomed the group and the meeting was opened at 5:15 p.m. The meeting
agenda was reviewed followed by an introduction of all attendees. A sign-in sheet was passed
around to record attendance.
Planning Team Issues
Jon Wade provided a rundown of the upcoming meeting schedule:
|October 10, 2000||Green River||5:00||TBA|
|November 14, 2000||Farson||1:00||TBA|
|December 12, 2000||Rock Springs||1:00||TBA|
It is noted that the November meeting was moved back from the 7th, which is Election Day. Jon
Wade then updated the group on the progress of the Bear, Powder-Tongue, and Northeast basin
Jon then discussed the dissemination of the various planning products. While products will be
available on the Internet, some provision must be made for those without Internet access. In
that case, providing the information on CD is a possibility. The planning team is trying to
avoid mailing everything as paper copy to the entire BAG.
Mr. Ben Bracken was introduced to the group to discuss the status of Huell Howser's video
production on behalf of the Colorado River Water Users Association. According to Ben, only
Wyoming and Utah turned in their agendas on time. Absent agendas from the other states, the
video will not be created in the near future. Ben isn't sure when the issue will be elevated
again. He will be traveling to California next month to discuss the matter further.
Pat Tyrrell of States West was introduced and presented an overview of the entire plan, in draft
form. The intention of this presentation was to give the BAG as much plan-generated results as
possible in one meeting, so that they can use the remaining project time to comment on those
results. Mr. Tyrrell then began the presentation, which first discussed current uses followed
by projected uses, both in reference to Wyoming's allocation under the Upper Colorado River
To review, Mr. Tyrrell presented current municipal and industrial uses, both using surface and
groundwater. Agricultural uses (depletions) were presented after discussion of the use of
diversion records, Consumptive Irrigation Requirement data and the estimation of "irrigation
days" in wet, dry and normal years. Mr. Tyrrell also explained that basins with storage
typically demonstrated longer irrigating seasons. A copy of the dry-year agricultural use
calculations was presented. Other uses, including evaporative losses from man-made sources,
recreational and environmental uses, were discussed individually. The reason for the relatively
large evaporation amount is that Wyoming's proportion of main-stem reservoir evaporation is
included (currently 88,500 AF). This number is not always included in depletion discussions
because it is not strictly an "in-state" use.
Following a discussion of current uses, a comparison of those uses to the compact allocation was
given. Availability numbers were discussed, with model results given on the screen (and on
poster-board). Surface water availability is a determining factor in future water development
Mr. Tyrrell then made presentations on projected uses, for low, moderate and high growth
scenarios. These uses were broken down by type, i.e. municipal, industrial, agricultural,
recreational and environmental.
Agricultural demands are the most difficult among the use sectors to project into the future.
Primarily, this is due to elasticity of demand, or the degree of effect cost has thereon. While
municipal and industrial uses are relatively inelastic (i.e. when a municipality or industry
needs water, they basically "go get it" with cost less of a factor), agricultural demands are
heavily influenced by the price of water. Hence, future demands for agricultural water are as
much affected by the financing terms for delivering the water as they are by the sheer desire to
add irrigated acres to an operation, or firm up a water supply. Therefore, the BAG was asked to
review the agricultural use projections carefully.
The presentation also included discussion of institutional constraints on water development as
well as a pre-list of items that will be on the first long-list of water development
As a homework assignment, Mr. Tyrrell passed out a copy of draft project ranking criteria
prepared by the Wyoming Water Resources Center in 1990. The BAG was asked to review these
criteria and discuss if these, or some other criteria, were appropriate for ranking the final
At the end of the presentation, comments surfaced regarding whether the BAG should contact
members of the Joint Agriculture, Public Lands and Water Resources Interim Committee of the
legislature to recommend their voting against proposed water law legislation (i.e. the salvage
water and temporary use rules discussed by Sue Lowry of the Wyoming State Engineers Office at
the last BAG meeting). After intense discussion, it was decided that the BAG would, if
anything, recommend that the legislature not pass this legislation until the basin planning
process is complete. Until that time, passage of such legislation would be premature. Joe Lord,
facilitator, was asked by the BAG to draft a letter for submittal to the Joint Ag. Committee (on
behalf of the Green River BAG members in attendance), which relayed these concerns and suggested
a course of action.
The meeting was adjourned at 8:00 p.m.
