resulting in aggradation in the lower Little Snake River channel. This portends a decrease in sediment yield to the Yampa River. RCI quotes Butler (1989) as stating that Sandstone would reduce sand loads to the Yampa River by about 12% over baseline conditions and 32% over historic conditions. This reduction in sediment load may impact the Green River, but RCI states that it is inappropriate to assume that the impacts on the Green River resulting from water development on the Little Snake River will be similar to the impacts of Flaming Gorge on the Green River. RCI (1991) also reported on the application of a bias correction factor to the rated curves. The bias correction for the log transformation of the regressed sediment load and discharge data tended to over predict the mean annual sediment load whereas the uncorrected rating curves underestimated the mean annual sediment load. As a result RCI (1991) only applied the bias correction to discharge data greater than 2,000 cfs (57 m3/s). This was justified on the basis that the sediment load for discharges less than 2,000 cfs (57 m3/s) is minimal. It should be noted that O'Brien (1987) adjusted the bias correction factor to reproduce the measured mean annual sediment load for the 5 years of data collected at the Lily gage. Lyons et al. (1992) investigated the Green River sediment transport data, aerial photography, channel width surveys, and previous studies analyzing the post-reservoir Green River morphology from about Jensen to Ouray for the period 1952 to 1987. This included an extensive analysis of Andrews' 1986 data on channel width changes. Bed material load mass balance and effective discharge was also evaluated. A review of the aerial photos from 1952 to 1964 confirmed that the active channels were more or less constant during this period (Lyons, et al. 1992). Andrews (1986) had concluded that a quasi-equilibrium existed between sediment load and channel morphology pre-Flaming Gorge. RCI (1991) 43
