<br />PLAN FORMULATION
<br />
<br />This alternative plan is based on an assumption that the oil shale
<br />industry would choose to develop its own water supply, or that the in-
<br />dustry would not materialize within the time period considered in this
<br />study. The chief project purposes would be the development of a water
<br />supply for coal uses, irrigation, and municipal uses, and of facilities
<br />or measures for recreation and fish and ~ildlife. In terms of cost, the
<br />plan would have the smallest scale of development of the five Federal
<br />development plans. The plan also presents a concept of low capital cost
<br />for irrigators. The use of open canal for conventional surface irriga-
<br />tion would require less initial investment for individual farmers than
<br />the relatively expensive equipment for sprinkler irrigation. The com-
<br />parative tables in Chapter V show the relative magnitudes of features,
<br />facilities, and costs associated with each plan.
<br />
<br />An annual water supply of 72,600 acre-feet would be developed for
<br />the project uses shown in the following table.

<br />About 11,140 acres would receive irrigation water, as shown in the
<br />following table. The full service lands to be served are now in culti-
<br />vated dry-farm production or improved range land. There would be no
<br />sprinkler irrigation in this plan.
