kunlun_shan, There is a description of the 1861 flood event in "Up and Down California" by William Brewer which is basically a diary of his years on the Whitney survey party from 1861 to 1864, most excellent read. Drop me a PM about skiing, likely heading out tomorrow for high ground.

A gust of wind hit the house night before last that was an easy 80 mph plus I thought it tore the roof off.

Floods are good the best fishing I ever had was after the 97 flood. Created a ton of new habitat and cleaned the river pretty well except for all the products that floated into the river after the wharehouses flooded in sparks.

Anyway we need it and we need it big. Flood away mother nature bring it on.

Hard to say how bad it will be. Hopefully not to many properties involved. But historically we get floods at least once every decade so most residents here are pretty aware if it is a problem for their home or business.

And that previous world record, according to Weather Underground, was 189 inches. But that took place in a six-day period. Not surprisingly, it happened at Mount Shasta Ski bowl (now Mount Shasta Ski Park) in February 1959, which was the first year that the ski resort opened.

From the newsfeed quoted, above. . .

WELL. . . just to set the record straight. . . The old Mt Shasta Ski Bowl (destroyed by avalanches in the 70s) and today's Mt Shasta Ski Park are two completely different things. . . in two completely different places on the mountain.

That alone, might render the above report a little shaky, not to mention the title of the article being:

record snowball in Mount Shasta

HA!

This system has been a lightweight for S Calif, only about a 1/2" storm total here.

It does look like a pineapple express flow is setting up pulling water up from over the SE Asia and off the Tibetan Plateau, then north of Hawaii. that's when it seems to hit us. Maybe we'll get a real storm in a week or so.

If the flow is up from the equator and south of Hawaii, like this system started out, it seems to hit north of Pt. Conception and we don't get much.

Here's the best piece I've seen on 1861.

http://www.redlandsfortnightly.org/papers/Taylor06.htm

No comparison at all to this. It destroyed 1/3 of the tax base in the state and drowned 1/4 of the cattle.

The flood ended the California cattle ranch industry and destroyed the ranchero social order.

For a week the tides at the Golden Gate did not flood, rather there was continuous and forceful ebb of brown fresh water 18-20 feet deep pouring out above the salt water. A sea captain reported that his heavily laden ship foundered in the Gulf of the Farallons off of San Francisco, due to the layer of fresh water. Fresh-water fish were caught in San Francisco Bay for several months after the peaks of the flood. These events have not happened since. (Ellis 1936)

bigs storms usually do mean great fishing in the bay. It's kind of like flushing the toilet. Out with the old and in with the new

Bluey.....nah....not the BIGGEST storm I've ever seen up here on Castle Rock Ridge. There was that one in......
but I digress
6" rain since Thursday. And still raining. 1" overnight and it didn't feel like it was raining at all by comparison to Thurs night.

c'mon up to Castle Rock for some slick rock bouldering.....bring your Wellies! your snorkel too and we'll do the falls routes.

For a week the tides at the Golden Gate did not flood, rather there was continuous and forceful ebb of brown fresh water 18-20 feet deep pouring out above the salt water
And now we have a dozen or so big dams on the Sacramento/San Joaquin so that's not likely to happen again.

In terms of the ability of dams to do much flood control in a storm series like those big historical ones, don't get your hopes up. Dams do a pretty good job on the normal and usual storms, as there is only so much water management they can accomplish. Once it gets a little unusual, like in 1998 when dam flood control was basically overwhelmed, dams pretty mcuh stop working, because when the reservoir is full, its like the dam isn't even there. Water in always has to equal water out, so those historical flood conditions might not be as unexpected as you are assuming.

The devastation caused by gold miners may have had something to do with the impacts of the flood of 1861. They created a huge amount of deforestation, especially in the foothills.

Yes, I was thinking about the possible massive overtopping. Less likely because with a forecast, extra water can be released from the reservoirs in advance. But still possible.

And then there are the unusual, but certainly possible again, conditions that created the Yosemite Valley flood of 1997.

MH.....yup.....also the upturning of the stream beds bringing rock to the top and placer mining washing the topsoil away.

Hydraulic mining was a minor contributing factor in the 1861 flood. Mostly in the debris that it liberated down stream that tore up log dams and retaining basins.

The Sacramento, and San Joaqin valleys were lakes for almost a month and Orange County was an inland sea for three weeks. Flow of the Santa Ana river at the narrows was an estimated 320,000 CFS To give that some perspective the average flow of the Missippi is 450,000 CFS.

Even the Mojave river was 20' above flood stage and most of the desert lake beds filled.

I doubt the flood cotrol system could handle it at either end of the state.

For example even if Prado Dam did hold in a repeat of 1861 there would be a deep lake streching from Pomona to Redlands and from the San Gabriels to Corona that would take months to drain without wiping out Anaheim and the coastal cities.

a RARE pic of,,,,"Ophir creek DAM".... Flood of 97- washoe valley, old us 395. Neeldess to say,, ol 395 was CLOSED lol!

About a million yards of granite and dg flowed down the highway to bowers mansion from the top of the hill at ophir creek crossing. You didnt do stuff like this every day...Used a few thousand yards in building the dam you see to re-contain ophir creek..

hey there say, TGT...

as to this qoute of yours:

WOW--the things that they did NOT teach us in our calif history...
wish they had...
thanks for sharing... i never knew of this...

hey there say, all you calif folks near this area:

brentwood, etc..


i got a friend there and she's said that she often wonders what wuold
happened, and/or, what it would take to make those levee's overflow...

she's fairly certain it just might flood her home, if they did...

they've had up to two inches around there home, from hard rains...
(not sure if she ment now, from the storm, or from a past one--put it IS raining-wet there, now) ...

thanks for any shares or thoughts or knowledge on this...
:)


edit:

say, i think, though i did not read the article, but:
it LOOKS like there is another storm system ALREADY coming
in, next, really soon?
