PARSHALL PROJECT, COLORADO

would receive additional water from the tributary streams mentioned and
the water would be replaced from the canal to the lower lands on which
it is n01v used.

The Big Lake ditch which diverts westward frOll! 1-Tilliams Fork River
about 7 miles below the Ute Park Reservoir site provides water for the
largest block of land presently irrigated in the Williams River basin.
The Parshall Flats Canal with a capacity of 30 second-feet would branch
from the Big Lake ditch a few hundred feet below the ditch head, cross
Williams Fork River 'by siphon, and continue northeast about 8 miles, pro-
viding water for presently dry lands located northeast of the Williams
Fork Reservoir. Irrigation laterals and drains would be provided as
needed, but existing facilities would be used for project purposes so
far as practicable.

The locations of project works and lands are shown on the frontis-
piece map. Physical data on project works and irrigated areas are shown
for each plan in the following table.
