Nice picture but I've never seen the water anywhere near blue like that.
That's a youtube thumbnail. I believe it's been altered, which also explains the strange brown substance that looks out of place.

Most of the video content has the correct coloring, from my experience observing the aqueduct.

I think it's edited to look like water he uses in his garage demos.
Really enjoyed watching that. Good luck with water LA.
I wonder at what point the up-front costs of massive desalination would overcome the (often hidden and externalized) costs of projects like this.

The California aquaduct system is an engineering marvel.
Being from LA, I am used to a water system that works without needing power. I think most of CA is like that. It was a surprise to lose the water back east when the power went out during a storm.
I was surprised to find out it was largely uncovered, though I guess it probably makes it much cheaper to construct. I usually think of aqueducts as pipes or tunnels, like Persian qanāts. I wonder how much water is lost due to evaporation.
I was in Owens River Gorge last week, it's a very interesting place. It has some of the tallest single pitch rock climbing in the world, sometimes requiring 80M ropes: https://www.mountainproject.com/area/105843226/owens-river-g...
The Owens river gorge has the highest concentration of sport climbs anywhere in North America, but there's not much variation, they're mostly edge ladders on weirdly slippery rock.

Not far away are the world's most photogenic boulders, the Buttermilks, and when I visited (from Canada) I was surprised to find that the boulders are on LA municipal property and the pipe that takes Owen's River's water over the Sierras is nearby.

Sometimes it feels like the US has lost its appetite for grand structural projects like that. Maybe it’s just that I’m unaware of them and that impression is the result of survival bias, but given how impossibly hard it is to just build anything where I live (Seattle), I’m not so sure.
The grand projects the US has embarked on have been completed using unethical means and without regard for real environmental consequences.
This particular grand structural project was never a good idea, as the video describes. So it might not be the best basis for comparison.
I really dig the editorial viewpoint of this article. New journalism style meets fun facts about engineering.
Growing up in LA, I was fascinated as a kid watching the water flow down this aqueduct. Anytime we drove by it on the way to Magic Mountain, I'd hope that it would be a water-on day.
The norcal/socal divide caused by the river is funny to me. I grew up in LA, then moved to the Bay Area for college. In LA we never really talked about where our water comes from. But we were always 'in a drought' and always taught to conserve water.

My wife grew up in the Bay Area, and was told the same.

But her family is from Sacramento. Up until about 15 years ago, everyone in Sacramento paid the same for water (based on square footage of your home). There were no water meters. So they didn't conserve. They ran the sprinklers in 100 degree heat for hours, they washed sidewalks with water instead sweeping, and all the other things.

But when the meters came, her Uncle blamed SoCal for "stealing his water". He complained every month when the bill came about how he has to pay more now because of SoCal.

I grew up in Sacramento and I remember when my parents were had a flat rate water bill. Those were the good ol' days!

It frustrates me how everyone moralizes water use rather than accepting that free markets allow for people who are simply willing to pay for it. For example, if you live in Sacrmanto and don't have a pool, you're just doing it all wrong (in my opinion, of course).

I watched my friend's family farm in Modesto flood their fields to irrigate them. No meter, just a valve off the canal and they pay a flat rate. So it offends me that my shower head is legally required to restrict it's flow. Or that neighbors decide that a pile of rock in the front yard is "better for the environment" as it radiates heat on a 105°F day...

I remember hearing years ago that this aqueduct was going to be shut down and then it just... never was? Does anyone else recall that?
Some say the LA aqueduct saved Owens Valley from development. (I’m sure the old timers out there would have a different opinion)
For anyone interested in a deep dive, I recommend the book Vision or villainy: origins of the Owens Valley-Los Angeles water controversy.
There's a poem carved into the stonework of Washington Union Station, part of the art installation The Progress of Railroading from c. 1909:

the old mechanic arts / controlling new forces / build new highways / for goods and men / override the ocean / and make the very ether / carry human thought

the desert shall rejoice / and blossom as the rose

Looking at what Tehran is facing (not related to the war, water shortage), I'm wondering why california isn't investing in more desalination for SoCal, especially for LA.

I see some here:

https://lynceans.org/all-posts/status-of-desalination-plants...

But there are only a few in SoCal and they're for smaller communities like carlsbad or santa barbara. So it is there and it is working for some, why not more? naturally i assume it's because everything costs more at the coast.

I’m in a rare community in Southern California (part of north county San Diego) where my water is 27% from the ocean (10% for rest of San Diego county).

It’s cool. Still totally hard and makes everything fail early.

Because the economics of desalination require locking in long term purchase/production rates at prices that dwarf current and other sources of water. SD's Poseidon desal is projected at ~$3.7k per acre ft for 2026 whereas SDCWA SWP water is ~$1.5-1.9k acre ft. Leak fixes, groundwater recharge, local aquifers, water banking, potable reuse, etc. are all more economical means of bolstering water supply.

A big factor in determining desalination placement in the region are the groundwater basins. Limited size and availability makes the case for desalination as means for resiliency. Another is that situating adjacent to power plants so as to use their already coastally degraded intakes/outfalls. Doheny is to use subsurface slant wells for intakes, but it's also lower output too.

As for LA. they're working on getting their potable reuse plants/projects up and running. The largest indirect potable reuse plant in the world has been operating in OC for ~18 years. Lower operating costs than desalination, reduced wastewater discharge, and reduced coastal impact.

The US needs a national water grid.

It would pay for itself after a few flooding events where were are able to redistribute the water more quickly. It also provides clean energy storage.

I've posted about it before with links to the studies but it usually just starts an argument by people worried the rest of the country is going to steal their water...

My favorite part of this video is where they divert and dry up one lake, and then build two reservoirs further downstream.
Pretty upsetting history along with the interesting engineering.
Is it really considered the Cascades all the way down near LA? I thought the mountains down there were the Sierra Nevada? Did Grady just get that detail wrong, or am I wrong in thinking that the Cascades stops in Northern California?
