PART VI

FUTURE DEVELOPMENT

e

Projections of industrial uses beyond 2000 were made
by Reclamation. These include 5,000 acre-feet of private rights devel-
oped for M&I purposes. Values shown are largely arbitrary and reflect
a growing use until the year 2040 when it is assumed that the State
will have reached its total Colorado River water allocation under the
Department of the Interior's present interpretation of total water
availability. No attempt has been made to identify individual indus-
trial uses.

a. Adjusted Comprehensive Framework Study

Several water uses listed in Table A were included in the
Comprehensive Framework Study. The Comprehensive Framework Study values
were, therefore, subtracted out to avoid double counting and are shown
below.

Navajo Reservoir evaporation
Hammond Project irrigation
Four Corners Powerplant
Total

31,000
10,000
15,000
56,000

b. Miscellaneous Additional Depletions

e

These are depletions that have come into being since the
Comprehensive Framework Study estimates were prepared. These include
5,000 acre-feet of private rights developed for municipal and industrial
purposes. Values shown were developed from data provided by the New
Mexico Interstate Stream Commission.

c. Navajo Reservoir Evaporation

Reservoir evaporation is based upon a 60-year Colorado
River Storage Project sequence study made in 1973.

d. Animas-La Plata Project (Colorado-New Mexico)

See discussion under Colorado on page 40. The New Mexico
Interstate Stream Commission estimates a depletion level of 14,000 acre-
feet by 2000. It is assumed the full authorized depletion of 34,000
acre-feet will be reached by 2010.

e. San Juan-Chama Project

e

The San Juan-Chama Project was authorized by Public Law
87-483. Transbasin diversions began in 1971. The May 1957 Supplemental
Project Report indicates that diversions are expected to average about
110,000 acre-feet a year, although more recent hydrologic studies per-
formed by the Southwest Regional Office indicate that the long-term
average annual yield may be closer to 104, 000 acre-feet. Historical
(1971-83) average diversion has been 99,640 acre-feet a year. For pur-
poses of this report llO,OOO acre-feet have been selected as the level
of existing and future average depletions.
