A few years back I had the great pleasure of water skiing in the desert on this lake, with Mr MF Mackin at the helm.

Seeing the water lines stories above our head, back then, was really eye opening. When a couple of us were dropped off to have more power to ski, once the boat turned the corner, we were all alone. It was surreal, like being on the moon with an oxygen atmosphere.

Super clear water. You could ski near the bank and see straight down the water was so clear, easily 30 feet.

Great memories from that day

It's crazy how much water is gone from there.

As I have said, to live in rural California is to experience persistent low-level stress about fire, wind and water. The latter takes many forms: drought, flood, blizzard. We don't worry about earthquakes much though.

In the two local drainages (Merced River and the Tuolumne River, which supplies most of SF's water), April 1 snowpack was just 64% and 63% of average, following on a low winter last year.

Giant sequoia still smoldering from 2020 Calif. wildfire
https://www.sfgate.com/news/article/Tree-still-smoldering-from-2020-Sequoia-National-16153776.php

After a not-tragic 63% of normal snowpack on April 1, the May 1 snowpack in Yosemite is at 25% of normal in the Merced drainage. In other words, three quarters of our water is missing. In Sequoia it was 59% on April 1 and presumably following a similar trajectory.

The upshot is that we did not get enough moisture this winter to fully extinguish the fire still smoldering from last summer. The last time I recall this happening was after the 2013 Rim Fire which happened during the severe drought of 2011/12 to 2015/16

The idea that golf courses and green lawns are tolerated in one of the hottest, driest places on earth is not just arrogance, but folly.

I don't understand the obsession. There is not a single lawn in our neighborhood of 200 houses and I would venture to say that if someone planted one there would be rebellion in the streets (basing that assessment on the outrage when there was talk of selling up to 5,000 gallons per day to a brand-new $12 million educational campus up the road that is unable to open due to lack of water).

>Lake Oroville

California's Sierra Nevada Mountains show what climate change can do as it worsens. The mountain snowpack, which provides 30% of the state's water supply annually, has vanished about two months ahead of schedule.

Water runoff from snow melt has been paltry, and major reservoirs like Lake Oroville are running even lower than they did during the record drought from 2012-2016.

Climate change is playing a key role in the drought, by boosting temperatures and increasing the loss of water to the atmosphere. Much of the snow went directly from frozen form back into the air, rather than melting into runoff.

Warming is also thought to be leading to increasing chances of dry fall seasons in the Golden State and shortened rainy seasons, according to Daniel Swain, a climate researcher at UCLA and the Nature Conservancy.

Good, bulleted article. Worth a scan.

Much of the snow went directly from frozen form back into the air, rather than melting into runoff.

More and more precip is falling as rain too. If the reservoirs are empty, that's fine, but if full, there's no storage.

I forget the exact numbers, but the historic (1970-2000) snowline was 5700 feet. Above that altitude >50% of precip falls as snow. I think a 2 degree rise pushes that to 7200. A 4 degree rise pushes it to 9000. Again, I forget the exact numbers, but it roughly means that you go from 20% of the park being below snowline to 20% being above. It might be more dire than that even. 15% sticks in my mind for one of those numbers

Don't quote me on that. I know most of those numbers are incorrect to some degree, but the general idea is that a relatively small increase in temperature makes for a large decrease in storage for the simple reason than mountains are pointy and get smaller as you go higher.

I don't have any data to back this up but based on what I am seeing they are really trying to keep as much water dammed up in the lakes and reservoirs as they can so there is irrigation water in the Columbia Basin this summer. One big lake up in Idaho we visited last weekend had the water level up 6-8 feet vs what it was about a month ago.

That sounds right. At least in CA reservoirs should peak in July normally (though it appears not this year). Essentially, most of the runoff is May-June and the biggest irrigation needs are June-September, so that ideally yields a high point in July.

Wildly so.  All I can think of is cooling towers or many, many miles of deeply buried pipe in a closed loop.  I guess it could be pumped back into the aquifer, but what would be the long-term ramifications of slightly raising the ground water temperatures? Dunno.

But the water could be potable (though it might be salty). The 'mineral water' discharge of my geothermal heat pump is fine to drink, in fact we use it for daily coffee lately.  So pump it into retention ponds then over to city reservoirs?

Thanks. Interesting read.

It seems that if San Diego can filter out feces, drugs, cleaning products, and make the water fit to drink, data centers could certainly treat their water and make it fit to recirculate as coolant.

One of the fundamental ideas in Marc Reisner's Cadillac Desert is that through most of the West, water is artificially cheap and that until it gets priced according to its actual cost, it makes sense to build a data center in the desert and let it use 1.25m gallons per day.

The book is old and there have been some positive changes. When it was written, many districts made it illegal to meter water. In other words, state law prohibited municipal districts from putting meters on houses or irrigation pipes. That's all past. In Fresno, as they rolled out meters sector by sector, they saw a 50% reduction in usage very quickly. But overall, I think most of what Reisner says holds up.

During the last severe drought, many farmers switched to *more* water-intensive crops.

Why? If you are the guy with the well and can pump enough water, you can grow those crops when others can't, so they're worth more. So hedge funds put millions into very deep wells so farmers could switch to crops that drank more water and made more money.

"As drought worsens, there are few, if any, protections in place for California’s depleted groundwater. The new law gave local agencies at least 26 years — until 2040 — to stop the impacts of over-pumping."

California enacted a groundwater law 7 years ago. But wells are still drying up — and the threat is spreading

I think I recounted that this is what was keeping me up. In 2020, I was telling everyone that I would be so relieved when Nov 5 was passed. They kept saying, "You mean November 3?" meaning election day. I said, "No, November 5, when our utility district makes the final decision on adding new customers to the water system."

In coastal CA and to some extent the Owens Valley, earthquakes are a significant threat. But for most of CA there are only two threats that matter: fire and water, and the both tend to be bad at the same time.

California's Marin County could run out of water next summer as climate shifts drought patterns
Quote
Welcome to the future in Marin County, one where a $2 million house with an ocean view doesn't necessarily come with a reliable water supply.

"There used to be at least 10 years in between droughts in California, which was time enough for water ecosystems to recover." No longer. The last California drought, which persisted six years, ended in 2017. The current one began three years later and poses an existential threat to places like Marin County, which rely on local water sources for most or all of their supply. The past year has been the second driest on record in California.
https://www.sfgate.com/news/article/California-s-Marin-County-could-run-out-of-water-16554942.php

Bolinas, which is in Marin but has its own water system, limits water use to 125 gallons per household per day. That seems lavish for someone living alone in an apartment, but draconian for a family like Littleman's...

We're anxiously awaiting the May 1 snow survey, the most important one of the year. The April 1 survey was 41% of normal in the Merced and Tuolumne River watersheds. This might rise a bit because we've had colder, wetter April.

Still, the 1.5 feet that fell on Thursday night is gone, so it won't change it much. Also, "normal" is a moving target. I assume that snowpack is like temperature in that it is a 30-year moving average. So 41% of normal in 2022 is not the same as 41% of normal in 1922.

>>wildfire

I was just going to post that. We took the niece to the airport and got caught on the wrong side if it and had to drive around. Living in the CA mountains (well, most of the state actually) in the summer is like going to Stoicism Boot Camp. "What will we do if we lose everything?"

The most active flank is an area that I have thought about skiing, but have begged off because it's a tangle of vegetation. Lots of fuel. On the other hand, the world has lost something like 20% of its sequoia trees in the last few years (and the grove in question lost six trees in a wind event last year). Thus there will likely be a lot of resources thrown at this.

After a day of unfavorable conditions, they have started up with the LATs and VLATs again (Large and Very Large Air Tanker). But there are only 200 personnel on this one so far, which is a drop in the bucket. On big fires, it seems like they don't usually start making serious headway until they get up to about 2,000 personnel. But we're only at 1,190 acres right now, so if they VLATs can hammer it until dark, maybe there's a chance they can keep it small. Most likely outcome is a significant fire for a month.

“This isn’t a drought, it’s something else,” he said. “Myself and other scientists are trying to use a different term: Aridification.”

Aridification is defined as “the gradual change of a region from a wetter to a drier climate.” According to Udall, it also means “declining snowpacks, it’s earlier runoff, it’s a shorter winter, it’s more rain, less snow, it’s higher temps. It’s drying soils, it’s severe fires, it’s forest mortality, it’s a warm, thirsty atmosphere.”

There is one point where he has video of the governor of Utah beseeching people of all faiths to pray for rain. The lip syncing is so far off, it seemed like a comedy voice over, not even very well done. But actually, it's legit. The governor did in fact make a video in which he says "we need some divine intervention" and says that if everyone prays together for the weekend of June 4-6, "we may be able to escape the deadliest aspects of the continuing drought."

As the Colorado River Shrinks, Washington Prepares to Spread the Pain - The New York Times

"The seven states that rely on water from the shrinking Colorado River are unlikely to agree to voluntarily make deep reductions in their water use, negotiators say, which would force the federal government to impose cuts for the first time in the water supply for 40 million Americans."

>> 205%

The bigger question is what percentage of the annual total is that? Answer, 100%. In other words, if we add nothing to the snowpack and receive as much snow as melts off between now and May 1, we will have a "normal" year.

Whether the drought is "over" or not is a somewhat different question. This may be a brief interlude in a long mega-drought or possibly turning the corner on a decade plus of drought. Not likely the latter.

California Wants to Keep (Most of) the Colorado River for Itself
https://www.nytimes.com/2023/02/23/opinion/colorado-river-california-arizona-drought.html

Quote
As climate change shrinks the river, California argues, it’s Arizona that should take the biggest cuts. If the water in Lake Mead dips below 1,025 feet above sea level, California’s proposal would cut Arizona’s allocation in half, but California’s share, which is already larger, would be cut only 17 percent.

Quote
A rapidly growing California could have locked up rights to the biggest drink of the Colorado River, but it needed the federal government’s help to build dams and canals — so it agreed to share the water with its neighbors.

For a good long time, that agreement was mostly theoretical. The other states hadn’t yet built sufficient infrastructure to access their share of the water. But by the 1960s, Arizona tried to build a canal to carry the river’s water to Phoenix and Tucson — and California fought hard to block it.

In 1968, California agreed to stand down, but only if Arizona agreed to give California priority if the river ever shrank. With no other way to get the water it needed, Arizona took the deal.

The biggest user of this water is to grow alfalfa, much of which is exported and the rest is used to feed cattle. It's a crazy crop to grow in the desert.

California Drought Status Looks Very Different After Extreme Rain and Snow (Newsweek via MSN)

Warm atmospheric rivers in California forecast could spell trouble for massive snowpack (Yahoo! News via MSN)

Majority of CA sites already past annual average rainfall (keep in mind, that we are almost at the end of the rainfall year - March is the last important month, so this is expected given two huge storm cycles)

Statewide daily snowpack readings (official March 1 numbers from manual surveys not in yet, so I assume this is based on remote sensing)

And this is cool - you can compare curves for the year with any other year, including record-setting 1982-83. In the southern and central parts of the state, we're close to those levels.

Can't find the link right now, but I saw something that said Lake Mead had risen something like three feet but Lake Powell only a foot and it is dropping fast. The article I did find from today said Lake Powell dropped 1.5 feet in the past 11 days and is only 20 feet from the level at which it can no longer generate electricity.
