Oroville and Don Pedro Dam and gold prospecting

(peaceful acoustic guitar music) – Hey! It’s Prospector Jess again. I wanted to talk a little bit more about this dam condition we have going on here. We now have Lake Oroville, and its dam is over topping the spillway, as well as Don Pedro, which is another lake here in California. Both of these are very large reservoirs, and they both are in gold country. So it’s of interest of us to look at when it comes to gold
and gold prospecting. The conditions that led up to this are related directly to what
we would global warming, but it’s natural causes,
not man-made causes. That is, the solar influx has changed due to sunspot activities
in the recent years. This is a very important thing, because it dwarfs anything
man would ever do. And it gives rise to
these atmospheric rivers that we’ve heard so much
about in recent times. These rivers can deliver
huge amounts of water, tens of inches in an overnight period, that when they go into
one of these reservoirs can cause them to over top
in a matter of days. So it’s an important thing to recognize. The thing I wanted to talk
about right now is erosion and how erosion takes place
and drives gold downstream. I’m gonna talk specifically
about the case of Don Pedro, because it’s something of
interest related to earth, wind, as in these atmospheric
conditions, and fire. So earth, wind, and fire. Let’s take a look. Oroville and Don Pedro dams
overflow, 2017 edition. So this is Prospector Jess. I’m picking up what we talked about, how massive atmospheric
rivers impact gold. Remember the pictures
we looked at last week. These are Oroville Dam going
over the emergency spillway, which is another word
for disaster in action. Notice the way it’s cutting a massive chunk of bedrock out right here, and it’s already cut the
road bed and well below it. When all this cleared out, there’s like a hundred foot
hole right in this area. And behind this is another
30 to 40 feet above that goes up to the top of the spillway. So this water is moving down pretty fast. Notice how red and muddy it
is, and if you look carefully, you’d notice it’s just
a big stream of gravel. It’s not really water. Another view. After it cleared out,
you can see this scoured all the way to bedrock down
the side of the mountain. Notice the beautiful striations of what looks like serpentine
formations, greenstone. This is a soft, ultramafic rock, and it is known to be
associated with gold. Notice the red water and the red soils. The redder, the better. Again, known to be associated with gold. Over here, we still have
the regular, standard, non-emergency but overflow
nonetheless spillway running berserko and cutoff
halfway down the mountain, and it’s also digging a massive hole, hundreds of thousands of cubic yards, from what I understand, of
earth that’s spilled down and washed out the mud and silt and left gravel and
any gold that was there down at the bottom in the riverbed. What happens is it’ll
come down these chutes and shoot into the river
flow, which right now isn’t moving very fast
at all except from this, and then it’ll deposit as
soon as it can downstream. So when you see this thing in pictures that were cleared out afterwards, you see these great big gravel bars all along where this
heavy, heavy whitewater is. So let’s take a look at another case. This is the Tuolumne River watershed, and it’s associated with the
Don Pedro Reservoir right here. Don Pedro has just now started
going over its spillway. It had done the same thing
20 years ago in 1997. So if you look carefully, you’ll see this is a huge amount of
acreage feeding that one dam. Now, I wanted to show you
something special, though, ’cause we talked about
earth, wind, and fire. Well, this represents the earth region for which the water will flow. This represents the outline of a fire that occurred in 2013. It’s called the Rim Fire. It was about 256 or 260,000 acres, a very large fire. That is dead center, for the
most part, in this watershed. Translation, this is all bare earth, very much like what you saw
on the side of that mountain, having water flowing off
of all these feeder streams into the Tuolumne River, which feeds the top end of Don Pedro. That means that water goes
in here and comes out here not a day or two later. And if there’s any snow back up in here, which there has been, that can melt due to these new atmospheric rivers coming from down near the Equator. That warm, moist air
will drop a lot of water, a foot or so, in a short period,
and melt the snow to boot and send it shooting down these areas, looking just like that
muddy thing we saw earlier. This is another outline of the same fire. You can kinda see the size of it here, and here’s Don Pedro in the corner. So over here is Yosemite
and Yosemite National Park. It moved right up into Hetch Hetchy, which is also a feeder reservoir
into the Tuolumne River, which feeds Don Pedro. Now this is another shot superimposing the two
effects and looking closer. You can see this blue line shows the major Tuolumne River Basin moving through this zone. This round line surrounds
the river drainage system. Right here, the arrow I’ve shown, is where the exit ramp and the overflow emergency spillway is, and you can see that feeds
into the Tuolumne River coming out here by
what’s called La Grange. And down below that it feeds
into the Tuolumne River, and that goes on into down
into the Central Valley. And right now, they’re experiencing
flood due to this thing, and it’s likely to get worse as each of these dams starts to overtop. The primary purpose of these
dams is for flood control, and it does a wondrous
job in normal years. This is an extraordinary
situation that we face, and I would say it’s really
extraordinary in the case where you have big fire
conditions in the backdrop, because that means these
flooded river basins will be moving gold and boulders and all kinds of mud and silt and sand that redeposit gold into
new pockets and plasters as we speak. And so it’s something to be
aware of in your hunt for gold, is how these atmospheric
conditions can in turn move gold and concentrate it in ways that you never would’ve thought of before. Here’s the Don Pedro
Reservoir spillway opening up and dumping over Bond’s Flat Road. They actually dug a whole
through it this time. In 1997, they weren’t ready for this and it wiped out this whole area. It was a pretty big flood, similar to what’s
happening up at Oroville. This is the residue after 1997, the New Year’s flood, they called it. They opened up the floodgates and wiped out this whole
segment down below, and it took out the road and
several things down below that. It was a bit of a surprise to them, so this time they’re a
little more prepared, but don’t be surprised if there’s more of this kind of damage. This is really what these
systems are designed for. The problem is, they need a higher lip. They need more capacity. And they need a little less politics controlling the actual levels, because what happens when you
start manipulating the levels, you guess it wrong, and
you’ll get a condition like one of these solar flares and the next thing you know, you’ve gotta have extra
room and you don’t have it. Or you don’t have enough room because you’ve already dumped
all your water downstream because of feeding the fish. It just doesn’t play to play God. So, in the meanwhile,
when the rivers clear up, don’t go out there now,
but when they do clear up, you should have a great gold season. Good prospecting. Prospector Jess, over and out.

  1. You were doing good until you said "due to atmospheric rivers down near the equator." What? All this rainfall is due to the tail end of El Nino. Now if El Nino is due to "atmospheric rivers at the equator," I don't know. Maybe you could explain that more thoroughly and discuss El Nino.

  2. Mainstream Media said that Vladimir Putin was Allegedly seen Riding a
    Tiger up the Spillway with a Pick Axe just before the hole was found :-}
    Как дела Плохо До свидания

  3. Jess HELP me find any water level Data for Dams on the Columbia River being many. Its as if there is NO DATA AVAILABLE. In light of all these dams are being comprimissed now Lake Powell is FULL and could pose a threat of tunnel cavitation. I am not bying the "This is by accident theory" I believe its deliberate. And when I posted on Facebook looks like Obama defunded Public DATA INFORMATION on the dams in NW before leaving office it was not allowed to be posted which tells me it could be classified information.

  4. I suppose the mayor will still want citizens to pay for all the repairs, even though he filled his bank with gold

  5. Now where did they haul off all the rubble they scooped out of the Feather river. Also you mentioned the red soil associated with gold, Orville dam used the gold mine tailings during it's construction & back then it wasn't worth getting out every fleck as it is today. I'm bet'n your right on about the migration of gold during these floods. Can't wait for you to show us how it panned out for you.

  6. The thing is, none of that new gold from above the lake is going to make it past the Dam. If one could legally dredge, then right at the mouth of the lakes would be there past to go.

  7. Flash back of 9/11 what happen to gold that bush had taken out from under the world trade center the day before it all happen i am calling bullshit brown is behind this and they fucking get away with it.

  8. You stated climate change is not done by man, but I have a serious question. Observations: the earth has never housed 7.5 billion humans to known history, the atmospheric CO2 has risen cointegrated with human population and accelerated cointegrated with industrialization, and the average global temp has also risen cointegrated with the population and CO2 curves. They are moving together. Is this evidence that human population and human activity is having an effect on average global temp? In the videos, notice the timing of the 3 factors….population, temperature and CO2. A first grade science experiment demonstrates how an atmosphere of more CO2 , when struck by photons, retains more heat than atmosphere with less CO2. In statistical analysis, when trends break, volatility ,or extremes, are observed. When global temp rises, polar ice melts, diluting the salt seas, raising the freezing point of sea water, causing more sea ice than normal during colder months and longer melting periods during the warmer temperature retracements, causing things like massive ice shelf cleavage, like what was observed in Antartica this past year. https://www.youtube.com/watch?v=PUwmA3Q0_OE&list=PL7BgC2rd3uXQu9KjDuXpkufKmkug33oSA
