corrected regression analysis). Whereas Elliott et al. (1984) and Andrews (1978) did not apply a bias correction factor, O'Brien (1987) and Koch and Smillie (1986) did apply the bias correction factor to the Lily Gage data base and computed comparable sediment loads. Based on the sediment rating curve derived for Mathers Hole, O'Brien (1987) showed that the sediment moving through Yampa Canyon was approximately equal to the upstream supply. This was confirmed by applying the sediment rating curves for the Lily and Maybell gages to the daily discharge for the period from 1921 to 1984 to compute an annual sediment load and then comparing it to the Mathers Hole predicted sediment load. The difference in average annual upstream sediment supply and the sediment load predicted by the Mathers Hole regressed rated curve was only 5%. The sediment load in Yampa Canyon is therefore supply limited and depends on the sediment transport capacity of the Deerlodge Park reach. O'Brien (1987) attempted to determine the effects of water depletions from the Yampa and Little Snake rivers by reducing the annual hydrographs in each river and computing a sediment budget based on the mean daily sediment loads calculated with the sediment rating curves. The drawback of this analysis is that the Mathers Hole sediment rating curve data is limited to two years of data and the rating curve data at the gages may have been shifting over the period of record. O'Brien (1987) concluded that some sediment storage should be expected if the Yampa River was depleted by 100,000 af per year or more while Little Snake River flows were undiminished. Two reports were prepared by Butler (1988a and 1988b) which address the Little Snake River flows and effects of reduced stream flows. The first report addressed the potential impacts of the proposed Sandstone Reservoir on the 36
