Table 7. Description of the transects used to describe hydraulic and habitat conditions at the Ruple Ranch study site, Green River (RM 332.3 - RM 333.0). Transect Description 1 and 2 Transect one is a good control for upstream transects. Narrow channel containing runs of moderate depths and velocities. .Cobble and sand are the dominant substrates with silt present near river left. The banks are sparsely vegetated sandy soil that adjoin a wide alluvial floodplain on river left and a sheer sandstone wall on river right. 3 A wide run with deep, slow moving water near the right bank. A large cobble bar is exposed near the left bank at lower flows. Silt/cobble is the most common substrate combination. Steep vegetated banks adjoin the wide flood plain on river left and a"-sheer sandstone wall on river right. 4 and 5 Wide runs of moderate depth and velocity. Depths and velocities are fairly uniform in this area. The dominant substrate at both transects is cobble; sand and gravel are also present. The banks are steep and sparsely vegetated. The wide bottomland adjoins the left bank;- the bank on river right forms the base of a very steep hill which lies between the sheer sandstone walls are prominent on river right. 6 An excellent control. This is the narrowest transect and is located downstream from a riffle. A deep pool with slow moving water, it contains a variety of substrates. Cobbles, sand, clay and silt are all present on this transect. Steep, narrow, sandy and sparsely vegetated banks adjoin the wide floodplain on river left and the sheer sandstone wall on river right. 28
