supplemented. This authorizes the Department to cooperate with other
Federal, State, and local agencies in making investigations and surveys
of watersheds of rivers as a basis for development of coordinated pro-
grams.

Survey work by the United States Department of Agriculture was carried
out by technicians of the Soil Conservation Service, Forest Service, and
Economic Research Service under the direction of a USDA Field Advisory
Committee, Colorado Rivers, composed of, representatives of the above
agencies.

This is Qne of a series of cooperative river basin surveys being
conducted by the U. S. Department of Agriculture and the Colorado Water
Conservation Board. Previous studies resulted in reports on Water and
Related Land Resources of the Gunnison River Basin (1962), the Colorado
River Basin in Colorado (1965), and the White River Basin in Colorado
(1966). Similar studies have been initiated for the Dolores and the San
Juan river basins.

This study utilized applicable data from previous investigations wherever
possible. The report is developed from field surveys and analysis of
material collected from many sources. It is presented in the form of an
inventory or information document rather than as an action or authorizing
report. The data provided will serve as a basic source of information
for use in the Upper Colorado Region Comprehensive Framework Study.

For these currently scheduled river basin surveys, hydrologic and water
supply studies are being standardized to include the years 1943-60 as a
base study period. These years have been selected because of the greater
availability of streamflow data and other necessary records, and because
they include periods of both above and below longtime average streamflows.
They are reasonably representative of conditions existing during recent
time periods and may be compared with other base periods through statis-
tical or analytical procedures. Where possible, other data within the
report have been developed for the same base period. There are some
instances, such as in recreation, where records are nonexistent or are
nonrepresentative of the base period. In these cases, use has been made
of existing information regardless of time periods.
