Hi Ray76, FYI - Here's a superimposed photo of DWR's captured geologic 3D image data with your original topo map & stream denotations. There is an addition topographic inferred stream erosion path marked in blue arrows. This path follows the edge of the main spillway. Note: the 3D perspective image is rotated in the Z axis with respect to the topo map. This shifts a bit of the alignment references (such as historic roads).
