Too bad they haven't figured out how to store the excess for future drought conditions.  What do you think they're storing behind that dam.

That's a good point, what's the elevation of the bottom of primary spillway gates? Looks like we're in the clear for now, will be interesting to see how much storage they're able to generate in the next few days, and how bad the next storm really turns out to be. We may end up seeing several feet of water going over the E-spillway yet. |

Then again, given the remote location, rough terrain, limited access, and the fact a Mavic Pro has a range of about 6 miles and 21 minutes flight time (plus 5 min. reserve), using autopilot to have it autonomously fly a path and the return to a hard to discover location, not much they can do about it anyway, lol. Piss on the gov idiots! |

So, flood-control capability seems to be gone or severely constrained. All they have is spillway flow diddling that to my inexpert eye seems like it will be quickly erased/overmatched by the next surge or water in "a couple" days?
What does that mean in terms of flooding downstream as the storms and spring melt pass over that structure? Is there enough information that someone can take the estimated volume of water to come down and timeplot that through computer magic onto a flood map? Kinda curious; people seem to be starting to look through this current flow toward the next one and its consequences. |

Quote HistoryQuoted:
They won't stop spilling out the primary for long...they really need the storage to be able to smooth out any inflow spikes that may happen this week. If you look at the p spillway damage it has migrated significantly uphill toward the gates. They will stop the flow to eyeball that when they can. Drones will be used. That erosion is the driving factor going forward and they need real facts to make good decisions about what spillway to use. They survived round 1. Once they get a little storage space they will evaluate and make a plan for the coming weeks. They need that power plant so clearing the channel and setting up new transmission lines will be a priority. Still if a major melt/rainfall event happens they are pretty screwed. No storage means it's just a wide spot in the river now. Quote HistoryQuoted:
