Thanks for the information.

Thanks ER333 for the corrected data width on the spillway. While my width was way off the point of how photographs don’t show the scale still applies I believe.

As another photo above shows, the water going into the lost gap in the spillway has eroded so much that it isn’t even making it to the end, I would still bet that the erosion has cut out a great deal in excess of the 20’ and once mucked out the fill is going to need to be 50 to 60 foot in height if they attempt to get back to original grade.
