Water rights for the 20,000 acre-foot irrigation pool will be
provided by transfer of the storage decree from the existing Model
Reservoir to the Trinidad Reservoir. The joint use capacity will be
used for the storage of irrigation water and for the accumulation of
sediment. The Trinidad Reservoir will store and regulate surplus
flows as well as flows accruing to the Model storage right. The use
of project water will be limited to 19,717 acres of irrigable land
to be served by the 11 existing ditch systems. Exhibit 2 is a
schematic diagram showing the general location of the various ditch
systems.

Because of erratic and poorly controlled water supplies, the
irrigated acreage served by the 11 existing ditches has not been
constant from year to year. Land classification studies disclose
that about 19,149 acres of land have been irrigated, consistently
or intermittently, during the 1955-1959 period. The following
tabulation summaries the classification and status of those lands:
