Huh. And this has Lowell George offering an oil check...

Aw, he's no fun, he fell right over.

It should be noted that the damaged spillway is a bit longer than a half-mile and about 150 feet wide. About 1/3rd of the way down a crack formed while the spillway was being used to move the excess water from above the dam and eventually it formed a hole that was at least 100 feet across and about the same along the length which was spilling out water at a tremendous rate towards (but NOT at) the dam itself. Most of that water continued down along the right side of the damaged spillway.
Remember that that Google Maps image was taken sometime during the drought which is why there is all that area surrounding the lake not covered by trees. Instead, imagine that all of the tan areas are covered by water as well. That grey rectangle at the top of the red arrow is a parking lot for a marina that was on the lake side of that grey patch, and the auxillary spillway is that thin grey line between the bottom-right corner of that parking lot and the top of the damaged spillway. The flow from that auxillary spillway is almost directly up-and-down in the image so somewhat following that trail you can see but there some fear that some of that flow can further undercut the damaged spillway.
We were discussing this today in the Engineering Geology class I'm sitting in on. Much of the area is underlain by volcanic rocks, and those weather into clays which like to swell when they're wet, and shrink when they're dry. The previous drought likely desiccated the clays underlying the spillway, and then the more recent rains rehydrated the clays, causing a rather sizable heave, which may have compromised the concrete in the spillway.
