<br />
<br />
<br />PLAN FORMULATION
<br />
<br />This plan would provide water for a large coal gasification indus-
<br />try, as well as for irrigation, and for a small oil-shale industry. In
<br />addition, recreational facilities, wildlife mitigation, and historical
<br />preservation would be provided for. A total annual water supply of 112,700
<br />acre-feet would be developed for the project uses shown in the following
<br />table.

<br />The project would provide a gravity-supplied pressure system for
<br />sprinkler irrigation in the Little Beaver area. In addition to increased
<br />efficiency of, water use by sprinkler irrigation, some land areas which
<br />could not be reached with surface methods would be irrigated. This pres-
<br />sure system is possible because the conduit required by year-round de-
<br />livery for coal industry use would also be available for irrigation.
<br />Irrigation water would be supplied to approximately 12,180 acres of
<br />land, as summarized below.

<br />Project plan
<br />
<br />Water for the Milk Creek Segment would be stored in Thornburgh
<br />Reservoir and released directly to the stream as needed. Water for coal
<br />industry use would be available at any point downstream to meet full
<br />industry needs. Irrigation water would be diverted to an existing ditch
<br />and delivered to presently irrigated but water-short lands for con-
<br />vention?l surface application.
<br />
<br />\~ater for the White River Segment would be provided by both storage
<br />and direct flows from the White River. Lake Avery would be enlarged to
