SUMMARY Summary Table S-l.--Short- and long-term impacts resulting from alternatives--AB Lateral Project (continued) Irre- versible Resource impact 1 Irre- trievable impact' Relationship of short-term use of environmental and long-term productivity Fisheries No Soils & vegetation Yes Terrestrial wildlife No Land use & recreation No Social and economic No cultural resources No Air quality No No Yes No No No No No Significant impacts to the Gunnison River fishexy would not occur. The Uncompahgre River fishery below the tailrace would improve as a result of increased flows but would decline through Montrose. Less than one percent of the populations of clay-loving wild buckwheat and adobe penstemon would be eliminated during construction of the penstock. Widening and lining of the AB Lateral would result in the loss of 4 acres of wetland. Bank stabilization along the Uncompahgre ,River would result in the direct loss of 11 acres of wetland and an indirect loss of 11 to 29 acres. Significant impacts to terrestrial wildlife would not occur. Significant land use Changes are not expected with development. Recreational rafting usage of the Gunnison River would decrease. Hike-in angler use of the Gunnison River Gorge would increase. Short-term employment opportunities would increase as a result of construction. Minor, long-term employment could also change due to increased revenues to Montrose county and the UVWUA. Development would decrease employment in the rafting industry and increase employment related to fishing. No impacts would occur to cultural resources except under alternative C, which includes enlarqing the Gunnison Tunnel. Short-term degradation of air quality resulting from construction equipment would occur. Development would reduce emissions of air pollutants from fossil-fueled powerplants. s - 17
