the Colorado River. Future export diversions include the
conveyance of an average of 40,000 acre feet per year from
the upper tributaries of the Yampa River for use in the
South Platte River basin of eastern Colorado, and the con-
veyance of an average of 3,300 acre feet per year from the
head tl~butaries of the Williams River for use in the White
River basin of western Colorado. The total anticipated
average annual depletion for the three export diversions
would be 46,100 acre feet.
The projected average annual water export diver-
sion from the basin is summarized in the following table:

Diversion for use in the drainage
basin of the main stem of the
Colorado River 2,800 Acre Feet
Diversion for use in the drainage
basin of the South Platte River 40,000 Acre Feet
Diversion for use in the drainage
basin of the White River 3.300 Acre Feet
Total export diversion 46,100 Acre Feet

Basin Runoff and Stream Depletion
The historic average annual basin runoff from the
watershed in both Colorado and Wyoming for the 18-year period
of study (1943 - 1960) was 1,502,900 acre feet. Of this,
1,297,700 acre feet originated on the Colorado watershed and
205,200 originated on the watershed in Wyoming. The 1,297,700
acre feet of historic runoff from the Colorado watershed added
to the stream depletion within Colorado of 85,900 acre feet,
