In about 30 minutes, it is predicted that the flow over the emergency spillway will stop because they are letting 100k down the regular but damaged spillway. If they pull this off they will avoid further problems for now.
However, keep in mind that rain starts again Wednesday night or Thursday morning. How much of a problem this becomes depends on how much water they can safely let out of the reservoir between now and then.
Also, I spoke now with my source, who tells me to look for a problem with a debris dam developing below the dam, and difficulty developing with water backing up into the powerhouse. Already today, the managers had to stop releases through the powerhouse due to too much water. As can be seen from some of the videos posted earlier today, the flow down the hill from the emergency spillway has deposited a big bank of mud and debris in the river, impeding the river's flow down canyon.
My source points out that the controls to the dam are in the powerhouse and thus they cannot allow that to flood. He told me that if he were in charge, he would be doing everything he could to cut an alternative channel or otherwise to keep a debris dam from developing, as water in the power house could conceivably cause the authorities to lose control of the dam operation.
He noted that with panic releases of 100k down the normal spillway, the huge hole there may be eroding back up the hill toward the gates. More will be known once they cut the flow, but it is something to watch, especially since the damage is unrepairable before the spring melt hits, and if the erosion gets too close to the gates, they will have to stop or slow releases.
He also agreed that there has been a colossal screw up here in managing the dam, and that the fingers of blame are being pointed behind the scenes. He predicted that there has already been "fisticuffs" in meetings at the top of the state water management over this highly dangerous and continuing crisis, and the botched management that allowed this dire situation to develop.
Although the immediate crisis seems to have passed, the evacuations are increasing in scope:
