Oroville Spillways Phase 2 Update Mid-June 2018

oritteropo says...

To add to @eric3579's comment, the work was fairly carefully planned to occur over Summer, and after the water level had been reduced, to minimise the chances that they would get caught out like that. The hydro plant should be able to release more water than required for the duration of the second phase of works.

Their first phase was designed to leave the main spillway usable over winter, so this second phase could commence afterwards. The emergency spillway was designed never to be used, it was more like a fuse to allow evacuation if the dam fails. The revised design, taking into account the fact that the emergency spillway was required, appears to have strengthened it enough to be used as a backup instead.

The repairs would have been a heck of a lot cheaper if they had been conducted a decade ago, although I do wonder if all the flaws would have been obvious at the time.

So what if they need to use either spillway before they finish this project? It looks like even the main spillway is a long ways from being complete. While the emergency spillway can probably hold off except for another emergency of course...

I'd imagine if I lived downstream I'd be thinking, a little too late on these repairs, given they were requested a decade ago.

When dad childproofs the BBQ

I'm in complete agreement, although there are some edge-case limits. I lost an uncle (well before I was born) to one of them.

Kansas winters are cold and dry. My grandmother liked to deal with both problems by putting a pot to boil on the stove. In the 50's, my father's 3-4 year old brother managed to get enough of a grip and yank on the handle of the pot to pull it over the edge and didn't survive the burns from the scalding water.

Burned fingertips? Lesson learned, will heal. Boiling water or oil? Better keep it out of reach.

BBQs and ovens and stove tops and other hot objects are all self-solving problems for kids who like to touch things. Warn them, tell them the consequences, and then they either don't touch it (Win) or the touch it and get burnt and never touch it again (Win).

I give you the rare upvote / *ban .
While this looks beautiful and fun, it's a clear self link.
I wish I could have gone out with them when I was there, but that was summer, and I think they can only go off road like this in winter.

Hard to have a discussion when the basic psychological concept that is endemic in society is not understood by one side of the conversation. Not really worth trying to dig out of that hole, in my opinion.

I do like your idealist view of how people SHOULD be. We aren't that way, of course. I wish it for all our futures.

Including men, and the internalized messages they get that warp their view of the world.

I have contended for years that men are in a much worse psychological state than women. We at least are encouraged to delve into our emotions, with varying degrees of success. Poor men are told to buck up and be "men". What a horrible thing to say to a little boy, or a preteen, or a teenager, or a young man entering adulthood, or a grown man dealing with a difficult world. No wonder men die earlier than women. The pressures they are under are enormous, with no way to relieve that pressure.

Generally speaking. There is a movement that has been gathering steam that is encouraging men to become more fully themselves.

The hike was great, albeit too short. We don't have great big waterfalls here on the Olympic Peninsula. It has been raining a lot lately. The waterfall that we visited was THUNDERING. I have never seen a thundering waterfall here.

Then again, I don't normally hike in the winter.

As for the weather... some Norwegian told a friend of mine -- There is no bad weather. Only bad clothing.

My clothing was fine, aided by the fact it started raining after we headed back home.

I don't doubt there are some people who exhibit an absolute psychological subversion to an ideology or person that is detrimental to their general good, ie. Stockholm syndrome, but to conclude that this is representative of even a significant minority of people who eschew victimhood in favour of responsibility for ones own situation is a long bow to draw. This is in the context of the last 20 years. Going back further to the time pre the women's rights movement or the abolishment of segregation, there are more empirical examples of internalisation.

Internalised whatever is a diminished capacity argument, limiting or removing entirely responsibility for ones actions and placing the blame elsewhere. An argument I find holds water if you're talking about blacks under Jim Crow where it would have been more desirable to either be white, or be closer to white, to escape oppression. Essentially a hostage situation.

It's a concept that loses steam as society becomes more accepting over time. Women now have the might of legislation + a significant chunk of the media behind them. They no longer have to be willing victims (although as #metoo showed, many were willing to be victims or at least silent via payout/nda when it served their purposes). If a woman is an equal to man, she must have the right to make her own decisions and the responsibility to be held accountable for them.

Hope the hike goes well. I imagine it's pretty chilly this time of year?

Snow Day Fun...

CrushBug says...

My uncle had a very large frozen pond in winter, out back of his house. He used to shovel a skating area with 2-3 foot high berms of snow around it. Then he would hook up a tractor tire inner tube and tow us around with a snowmobile. It was the greatest day when we figured out how to put the tube on the other side of the berm and use the snowmobile to launch us off of the lip. We were thrown so high in the air we felt like we were flying, and only manages to land back on the tube about half the time. Didn't stop us from doing it for hours, despite the impacts.

if it's such a bulky machine, why not make it regular bike sitting position with an encloded cockpit? Better visibility and warmer in cold Swedish winters.

Fear No Weevil: Taking on the World’s Worst Weed

oritteropo says...

Nutria don't die off every winter, so the weevils are likely to be less of a problem. There was actually a small scale trial before they built the weevil greenhouses, which didn't uncover any major issues with them.

See https://features.texasmonthly.com/editorial/creature-green-lagoon/ for many more details including the lack of frost tolerance:

Still, their campaign faced a significant obstacle: Caddo’s unfortunate latitude. The bug, like the plant it craves, is tropical. Problem is, weevils are felled by frost, while salvinia can stand slightly lower temperatures. This has proven to be Caddo’s curse, said Julie Nachtrieb, a biologist who raises and studies salvinia weevils at the Lewisville Aquatic Ecosystem Research Facility, part of the U.S. Army Corps of Engineers. In places with mild or even nonexistent winters, weevils can be released a few times and then “you can walk away and let nature take its course,” she said. But at Caddo, the weevil populations must be reconstituted every spring, giving salvinia a running start.

newtboy said:

I hope this goes better than the introduction of nutria, which Texas did to combat other invasive water weeds. They are now a major problem, causing massive erosion problems and displacing naive species. It makes me wonder what problems these weevils are going to cause in 10 years....how many native plants will they eat to extinction?

Lawn Bubble

Stormsinger says...

I had to think back a bit...it's been a few decades since I spent any time on a lawn of zoysia. But once I thought a bit more carefully, it does seem that zoysia changes it's texture with the season. Over the winter (and dry times) it gets tough and spiky, like walking on a bed of nails. But during the (limited) times when it's fresh and green, it is pretty soft. I think you can tell which season sticks in my memory.

On the bubble or on the zoysia? Based on my limited reading zoysia is really soft.

I was in that exact space a couple weeks ago, had no idea this was part of the Winter Carnival or might have tried to go watch. Totally keeping it in mind for 2018. Good Pokemon hunting there too, so extra bonus!

I'm gonna have to try and go to this next year.
