I was just watching Ryan McBeth on YouTube and he's attributing that north end spillway/bridge damage to Russians around Nov 12th, as well as showing some satellite imagery I hadn't seen before from March to June this year, suggesting structural failure.
Ryan's video (link in previous) was curious enough that I took a closer look at the satellite images he purchased and shared. Cropped & annotated versions attached. It certainly looks like the dam may not have needed a detonation to collapse - it may have simply spilled over due to neglicence!
