I have not seen it yet, but it sounds like it's where a steep short half assed clay bank is visible, that runs out to a shelf on the hatchery side, that gets deep on the edge? In years past I have stood on the shelf and bank fished it. It must drop into that deep hole causing the boil. Wonder if the left finger of the split can get around it? You can see it on Google Earth or Maps. Being technically challenged prevents me from posting the aerial view. Many steelhead showing up yet?
