<br />Pw'!:PORT OF THG ELEGIONAL DIRECTOR <br /> <br />Plan of Development <br /> <br />5. To bolster the livestock industry through irrigation, the <br />Lyman project would be undertaken by the Bureau of Reclamation to pro- <br />vide urgently needed supplemental water forapproxirnately 40,600 acres-- <br />the amount of land presently irrigated. It would incidentally improve <br />the area's domestic water supply during the late irrigation season by <br />augmenting the supply of its wells with unavoidable seepage from irri- <br />gated lands and distribution canals. The project would result in only a <br />negligible reduction in fish and wildlife values since all practicable <br />provisions have been made for their preservation. HydrOelectric power <br />development in connection with the project would be infeasible, and recre- <br />ational values would be only slightly impro",~d. Industrial water supplies, <br />flood and silt control, navigation, stream pollution abatement, and Indian <br />lands would not be affected. <br /> <br />6. To provide the additional late-season irrigation water, an <br />earthfill dam would be constructed at the Bridger site on Willow Creek <br />to store the spring flood flows of Blacks Fork and ~ts tributary, West <br />Fork of Smiths Fork. Surplus flows of these streams, now largely used <br />for e.xcessi ve irrigation in the spring run-off season, would be diverted <br />to the'reservoir through a canal of 6$0 second-foot capacity diverting <br />from Blacks Fork and through a canal of 250 second~foot capacity diverting. <br />from West Fork of Smiths Fork. The water thus diverted and stored would <br />yield an average of about 32,500 acre-feet of late-season water annually. <br />It would be retained in the reservoir until needed and then released into <br />
