This is an area on the North Fork of the Holston in Smyth County, approximately three miles above Saltville. It extended from the riffles approximately 600 feet upstream from the bridge on State Route 633 to about 300 feet upstream from the bridge. The river bed in this area was mostly sand and gravel although some bedrock was present. Patches of Potamogeton and Chara were common. In the riffle were rocks and rubble. A small island covered with Polygonum occupied the center of the station. Scattered here and there were very small patches of mud. The immediate banks were grassy. They merged almost immediately into the edges of the flood plain which were covered by deciduous trees - sycamores, walnuts and willows. Behind the trees on the right bank was crop land, while on the left bank the trees gave way to pastures. These trees bordering the edge of the river produced a considerable amount of shade.
