This is the video linked above, which was made yesterday in anticipation of the main spillway being used again in the next couple of days. The relevant part starts at 2 mins. 30 secs. in and continues to about the 10 min. mark. In the first part of that recording there is a reasonable high level view of the present condition of the areas at the base of the spillway where any discharge of water is likely to enter the diversion pool: Source: https://www.youtube.com/watch?v=qIwzJ0Dnz9E This is another one of Juan Browne's videos although much more on point than the last one linked in post 1437 above that concerned the river outlet valves. On that subject, there is a useful (largely speculation-free) news article here: https://yubanet.com/regional/key-oroville-drain-plugged-as-heavy-storms-pounded-the-reservoir/ One of the things it notes (not included in the Browne video) is "Because the river outlets are also the lowest drain in the dam, they have become important for accessing the coldest water at the bottom of reservoir to sustain endangered salmon runs. But they have rarely been used for that purpose until recently." Browne's thesis is that the river outlets, if run at full capacity, combined with the Hyatt Power Plant output could cope with the current inflow into the reservoir thus sparing the main spillway from use for another extended period. That does not seem realistic given the actual purpose for which the river outlets were designed and the possible impact on the river habitat of drawing water from the colder depths of the reservoir.
