they plan to start releasing from main spillway; water level in the lake is near that point.
860 feet is their magic number, but I think that they might hold off. If they use it now, they will be bringing down a lot of debris from the unscrubbed area just below the end of the intact portion of the main spillway. If they can hold off a few more days and get that area contoured and hardened, they will have time to clear out a better path down at the bottom in the retention pool. And they will have a much more secure surface for passing water which will result in less loose debris carried down into the river below.
The bulk of the eroded area is already scrubbed down to bedrock so it shouldn’t erode much if spilling isn’t extreme. Its just that area directly under the intact part of the spillway that is a very potential area for erosion.
I think that they could ramp up the plant enough now to carry the average incoming water and perhaps a bit more. Barring wet weather or a significant thaw up on the mountains, they should have several days to work with. They’ve gotten over 1/3 of the debris removed from the pond already.
Hold on! It could get bumpy.
