<br /> <br />'. ,"' <br />'O.A ;~~ 'l <br />. U L- Jj-j"j <br /> <br />. <br /> <br />. <br /> <br />8 <br /> <br />project area. This would amount to about 600 man-days annually <br />comprising 100 man-days of pheasant hunting, 100 man-days of dove <br />hunting, and about 400 man-days of rabbit hunting. Thus the water <br />salvage project would result in a loss of 2,600 man-days of upland- <br />game hunting comprising 1,100 man-days of pheasant hunting, 100 <br />man-days of dove hunting, and 1,400 man-days of rabbit hunting <br />annually. <br /> <br />The project would eliminate important waterfowl production and win- <br />tering habitat in the water salvage area of the Closed Basin. Low- <br />ering ground-water levels to a minimum of 8 feet below the ground <br />level would reduce the vegetation to a varying extent over at least <br />100,000 acres. Construction of small surface drains to divert ir- <br />rigation return flows and ponded water into the main channel would <br />materially reduce available wetland habitat in the project area. <br />As a result, some 100,000 acres of seasonally flooded wetlands of <br />value for waterfowl production and migration would be lost. A rest- <br />ing area would be established in the main channel and the laterals, <br />but nesting would be insignificant because of the lack of food and <br />cove r. <br /> <br />Lowering the water table 8 feet would eliminate much of the water- <br />fowl hunting in the project area. Some waterfowl hunting would re- <br />main along the 39 miles of the main conveyance channel, the 92 miles <br />of laterals, and on San Luis Lake. Waterfowl hunting with the proj- <br />ect would average 1,000 man-days annually. Other wildlife-oriented <br />recreation would be concentrated around San Luis Lake and would aver- <br />age about 500 man-days annually. Thus, the water salvage project <br />would result in a loss of 1,200 man-days of waterfowl hunting and <br />500 man-days of wildlife-oriented recreation. <br /> <br />The project would eliminate fur-animal habitat, thus reducing the <br />population on the project area. Trapping would continue at a low <br />level. <br /> <br />Table 2 summarizes wildlife and wildlife-oriented recreation with- <br />out the project and with the project. <br />
