• E-16 and E-17 had several feet of scour and deposition. The high flows lowered the E-16 thalweg by 3 ft while creating a sand bar off the right bank 4 ft high. Conversely, the E-17 thalweg was filled with 3 ft of sediment. •E-17.5 experienced the most radical response to the high flows. A left bank sand bar was deposited 9.5 ft higher than the original bed at the thalweg. At the same time, a thalweg developed at the original location of the center bar where the bed was lowered by 5 ft. High flows also created a sand bar on the right bank. •The last cross section of the entire river reach E-18 was left with a sand bar extending from the right bank approximately 200 ft to mid-channel. In summary, some of the cross sections experienced very dramatic changes mostly involving sand deposition or sand bar removal. Throughout the reach, more cross sections experienced net deposition than scour by a 10 to 6 ratio. The implication is that more sand moved into this reach than was transported out of the reach. The height of some of the deposits surveyed in August indicated that large volumes of sand were in transport during the peak flows. B. Wetlands Topographic Survey. One day in August was devoted to a preliminary survey of the Escalante wetland area. The purpose of this survey was to determine the potential for restoring the wetlands by inundation with Green River high flows. Several survey control points were established using a total station and two geodetic state plane coordinate benchmarks. From these control points several of the cross section endpoints were surveyed to establish elevations for the spot surveys in the wetlands. The following features were surveyed: • The excavated earth levee near the river paralleling this reach of river. • The cross section left endpoints where they could be viewed. • Five wetlands cross sections across the upper reach of the wetlands to locate an inflow channel to the area of ponded water. • A portion of historic meander thalweg of the eastern most channel along the bluff overlooking the wetlands. • Several wetland water surface elevations. • A return flow drainage channel from the wetlands to the river. 15
