New April 19 DWR photo captures a view of the Optical Target Panel. Hi Resolution zoom of the target reveals a "downslope shift" of up to a max of 1.16 inches with a 0.87 inches mean avg. note: EXACT value not released or noted to public by DWR.
Very troubling that the last section of “intact” spillway has moved. They’ll probably have to demo that part during the rebuild. I can’t imagine any technology that could “shove” the entire section back into place.
Wonder if the anchor bolts sheared, or the rock beneath the slab moved?
so what exactly does this shift mean? If it shifted 1 inch at that location does that mean it has shifted more than 1 inch at the end of the spillway since its 50 feet away and at an angle?
