The first was earlier today, the second is closer to the present.

Given enough time, moving water wins, every time. The generator outflow is unusable, the intakes are clogged. The primary spillway is slowly self-destructing, despite being run at about 25% designed capacity. The emergency spillway is holding up, it appears, but it is an uncontrolled spillway, which simply allows water, of any amount, to spill over its top. I hope the bedrock lasts longer than the rainy season and snow melt. |

Spillway Failures Are How Many Earthen Dams Fail! Read this and read this carefully Overtopping or overflow of an embankment dam beyond its spillway capacity will cause its eventual failure. The erosion of the dam's material by overtopping runoff will remove masses of material whose weight holds the dam in place and against the hydraulic forces acting to move the dam. Even a small sustained overtopping flow can remove thousands of tons of overburden soil from the mass of the dam within hours. The removal of this mass unbalances the forces that stabilize the dam against its reservoir as the mass of water still impounded behind the dam presses against the lightened mass of the embankment, made lighter by surface erosion. As the mass of the dam erodes, the force exerted by the reservoir begins to move the entire structure. The embankment, having almost no elastic strength, would begin to break into separate pieces, allowing the impounded reservoir water to flow between them, eroding and removing even more material as it passes through. In the final stages of failure the remaining pieces of the embankment would offer almost no resistance to the flow of the water and continue to fracture into smaller and smaller sections of earth and/or rock until these would disintegrates into a thick mud soup of earth, rocks and water. Therefore, safety requirements for the spillway are high, and require it to be capable of containing a maximum flood stage. It is common for its specifications to be written such that it can contain a five hundred year flood.[5] Recently a number of embankment dam overtopping protection systems have been developed.[6] These techniques include the concrete overtopping protection systems, timber cribs, sheet-piles, riprap and gabions, reinforced earth, minimum energy loss weirs, embankment overflow stepped spillways and the precast concrete block protection systems.

Spillway Failures Are How Many Earthen Dams Fail! This is a huge developing story and needs to have major attention on it. I had another thought as well...Everyone knows that the weight of WATER is significant in triggering fault lines. If this dam should suffer a major breach and that water does flood the Sacramento Valley, the water-weight it gives this land mass so close to San Francisco is like a mouse triggering the ACTION at the bottom of a mousetrap. Let's all pray the Oroville Dam stays in tact. A runaway train is a sad thing to watch. This situation is beyond bad. Great job, OP! "Know ONE thing absolutely...and you will UNDERSTAND everything.
