| Relation | Central Utah Project; Western Waters Digital Library; this his water allocation could be provided by the water rights associated with the lands to be acquired under the proposed action approximately 60 irrigated acres could be acquired under baseline conditions and an additional 23 233 3 acres could be acquired under the proposed action the morse decree 1921 allocated up to I 1 1 cfs cs per 60 irrigated acres in heber valley outside of the north fields area during the growing season at this rate a water right of up to about 3.9 39 39 cfs cs could be acquired by the federal gov government emment as part of the public access requirements in normal hydrologic years this full fuli water right can be supplied at the beginning of the season but available water falls to about half the right by the end of the growing season this would be su fLient sufficient faient to support the proposed off channel features side channels and ponds map al A l 1 in the map pocket at the back of the EIS shows typical locations of side channels these features would be refined during final design based on local topography soils vegetation landowner preferences and other factors table 16 1 6 lists potential side channel lengths by stream reach approximately 5 50070 0070 feet of side channels would be constructed including 19340 feet 39 percent within the core area 1523 1533 L 1523 523 5.23 152.3 523 setback dikes setback dikes would be required in some areas to limit the 100 year floodplain flood plain to nonhazardous non hazardous areas after removal of the existing dikes setback dikes would have a typical height of 2 to 4 feet and atop a top width of 15 to 3 30 0 feet figure 16 1 6 shows a schematic of a typical setback dike they would be designed to blend in with existing fields and pastures to minimize visual impacts setback dikes would be located far enough from the channel to maintain geomorphically morphically geo suitable floodplain flood plain conditions most setback dikes would be located at the edge of the core area in some locations setback dikes are proposed at the margin of the expanded restoration area in locations where the expanded restoration area is not acquired setback dikes would be constructed at the edge of the core area and the 100 year flood event would be contained by the setback dikes A revegetation and monitoringmaintenance monitoring maintenance plan would be developed for the setback dikes as part of final design setback dikes would be re vegetated to 1 blend in with the restored n riparian panan zone revegetation methods are discussed further in section 196.1 1961 if property within the expanded restoration area is acquired some setback dikes would be located at the boundary of those areas locations of proposed setback dikes are shown on map al A l 1 in the map pocket at the back of the EIS table 14 1 4 lists setback dike lengths by stream reach 152.4 1524 abandoned channel abandoned reaches of the existing channel that are not in locations of proposed wetlands ponds or side channels would be filled to the new floodplain flood plain level figure 17 1 7 shows how the abandoned channel cross section would be filled these filled areas would be re vegetated and integrated into the adjacent land the source of fill material would be from excavation of the new channel because the project would have excess excavated material compared to fill requirements placing material in the abandoned channel reduces off site disposal haul requirements the abandoned channel areas that would be filled are within the baseline public access corridor and would remain in public ownership under the proposed action therefore none of these areas would be available for agricultural uses map al A l 1 see pocket at back of EIS shows abandoned channel areas that would be filled other sections of abandoned channel would be set aside for development of wetland side channel and pond features these features have been conceptually identified at this time and the impacts reported represent a worst case or maximum condition for analysis however specific decisions on treatment of particular sections of abandoned channel would be made during final design 152.5 1525 jordanelle Jor danelle wetlands the proposed action would encroach into some of the US bureau of reclamation USBR constructed jordanelle Jor danelle wetlands area to develop sufficient floodplain flood plain width in reaches 8 and 9 this would require relocating some of the outside wetland dikes and removing imported wetland topsoil to lower the ground elevation to the new design floodplain flood plain level A cross section of the typical encroachment into the USBR wetlands is shown in figure 18 1 8 dikes would be reconstructed to confine the wetland ponds at the edge of the new floodplain flood plain removed topsoil would be salvaged for use elsewhere in the project |
