Since we've morphed beyond Mead, if CA is having so many ppower and water problems, why are they closing 4 dams?


Did you read your own article?

"The dams don't store agricultural water, aren't used for flood control and aren’t part of the 200,000-acre Klamath Project, an irrigation project further north that straddles the Oregon-California border. Removing the structures would affect homeowners who live around man-made lakes created by the dams.

If the dams remained, PacifiCorp would likely have to spend hundreds of millions of dollars to retrofit the structures to comply with today's environmental laws. As it is, the utility has said the electricity generated by the dams no longer makes up a significant part of its power portfolio."

Why dont we just build a pipeline from the great lakes to cali?

Yes. The fox ravaged one hen house, let's give him access to another, bigger one..

No! Children need to show they are ready, and have learned a lesson, before they are trusted with greater responsibility.

Do the math on how big that pipeline would have to be. Just the canals around Fresno are ~20 feet wide and 6’ deep. We are talking about a Colorado River size pipeline spanning 1,000 miles and climbing at least a mile in elevation.

Okay, I did the math. Assuming you completely replace the Lake Mead flow of 9.8M acre-feet/yr. You'd need a 60 foot diameter pipeline, the never had down time.

Even if you just made up for the current annual deficit it would need to be 21 feet in diameter.

The pumping energy would likely represent at least a few new nuclear power plants.

It makes more sense to send the water from the Columbia River in Washington state. They need to reroute the Columbia River from Hanford which is a superfund site. We also need a pipe from the Pacific through all the rivers and stream along the journey for salmon. There is an unlimited supply of fresh water there. We have these rivers that flood every season in Washington. They could build overflow (parallel to rivers) pipelines that run empty and dry until the flood season. When the rivers flood they would channel excess water through gates along rivers that would open during flood conditions. They could feed into the Columbia pipeline.

It makes more sense to cut off CA, AZ and NV from use of excess water, not local to them. If it isn't in your immediate area, tough noogies.

Pretty sure it's still cheaper to ship snow from canada by train than it is to desalinate ocean water to the levels it'd require for our southwest needs.

Really this whole thing is like watching someone play a civ game that's terrible at it. Like missing all the terrain bonuses, ignoring logical places for cities, industry, etc. Put people where there's no food or water? Sure! Put crops where there's no water? Sure! Solar panels in the desert? WHOA NOW, NO CRAZY TALK ROUND HERE.
Is it really cheaper to send snow over distance by rail?? It seems pretty obvious to me that long-term, California will have substantial desalination plants.

Outside of the Southwestern deserts, most of the larger SW region is fairly hospitable. There's just too much population and agriculture for the available water to serve. Las Vegas and Phoenix metro areas are still growing briskly.

You are aware the water comes from the Colorado River and it is the border for all the states you are saying it’s not local to them. It’s part of their border, ie they are down stream. Which is why the federal government determines the allotment between the northern upstream states and the southern downstream states.

What we need to do is stop wasteful at practices. Growing nuts, alfalfa and corn in arid climates is stupid and wasteful.

Non ag use accounts for 20% of the use of the Colorado River water. Take out the commercial bottling of water and residential use from population growth is fairly small.

Ag is the main problem, followed buy commercial uses, and residential use is the least biggest concern.

I was making a joke, desalination is incredibly energy intensive though. They do make use of it, but not nearly as much as simply draining lakes elsewhere.

I'm curious what he expects the government to do.

Will an unsustainable situation back into what we perceive as normal I guess. Somehow.

The places with money, like Southern California, are doing things though. They're investing heavily in water recycling projects having decided supplies of imported water might not always be available at historic levels.

Keep pumping til the pump stops working.
And then dig deeper wells to drain limited groundwater reserves, undercutting neighbors, until the groundwater reservoirs are all also permanently depleted - down to several thousand feet underground. Then continue to whine about it and beg for further major government subsidies to truck in water to keep the almonds growing.

This is acceptable.

If you think nuts and trees consume water, you should check out how much water is consumed by cattle and pork.

Your going after small potatoes while ignoring extreme waste in the ranching states.

Maybe almonds should be grown where there is still an abundance of water. Obviously not California.
