30% is 16.5 Billion gallons.
OP is saying that much rain got into a reservoir that sits on top of an ancient volcanic caldera and has no rivers flowing into? Unexpectedly? and they didn’t think to stop pumping water in from the South Branch or release some water?
The math ain’t mathing.
- joecool1029 2y agoIt's not at full capacity yet, they are pumping into it daily (around 200 million gallons) until it is. Only spruce run reservoir upstream of it fills naturally (and is spilling currently). Operations data for the reservoir updates every morning during workdays, so we'll know Monday if they paused pumping into it after the quakes, I don't have any better than daily numbers for it. Letting the water down isn't an option, most of the downstream gauges on the south branch were just at or near flood stage.

- joecool1029 2y agoJust to follow up on this, there was another way to tell they maybe shut the pumps off for a few hours after the quake (and I linked it in the same comment).
