That section you were worried about near the parking lot IS the emergency spillway. Water was over topping the dam there as it is supposed to. They were worried about erosion at the base of that spillway as it had never been used since the dam was built. The hole in the main spillway was another problem altogether.

No, if you look at pictures from the time that the emergency spillway was in use, you’ll see the outflow from it, but look to the left (while looking up the hill) and you can see two relatively small trickles of water that appear to be well to the northeast of the emergency outflow. It starts downslope from the crest, so it doesn’t appear to be from overtopping, but perhaps from a sand boil.
