Year-to-year variability isn't enough to make up for cumulative multi-year effects. See this UC Boulder webinar - here's the timepoint where they discuss multi-year droughts:

Notice the increasing tempo of drought frequency? That's in line with long-term climate model predictions of the drying of the American Southwest, linked to a general trend of rising interior temperatures in midlatitude continental zones (in particular, decreased soil moisture, declining summer snowpack, possibly expanding Hadley cell circulation).

It might be true that these reservoirs could be refilled if most outflow was eliminated, but that would mean the end of regional agriculture and severe restrictions on household water use across the entire region.
- WalterBright 4y ago> severe restrictions Why do people always turn to regulation and rationing rather than simply increasing the price of water?
- photochemsyn 4y agoEssentially the effect is the same, but one reason is reducing conflict. A bidding war over water rights, for example, might mean that some regions don't get enough water to survive while others get enough to keep their golf courses green. Historically in the American West, that kind of thing has led to people dynamiting canals and so on. A more balanced option might be setting a minimal delivery baseline for everyone in the watershed, with prices rising steeply above that baseline for the remaining water. This would encourage adoption of recycling, aka 'toilet-to-tap'...
- Ancalagon 4y agoNot to mention restricting water use for agriculture would more than solve the problem for residential users.
- fallingfrog 4y agoBecause the people with the most money (golf courses) and the people with the most legitimate need for water (thirst) are not the same people. Many Americans have this bizarre fixation on the idea that markets are magic and freedom means that whoever has the most money gets whatever they want. Sorry but that is an incredibly cruel and inefficient way to make decisions.
- RhysU 4y agoI would rather accept the wisdom of the cruel and inefficient markets, in which literally the whole world has input in some fashion, over the edicts issued by a local board of the well-connected and appointed.
- fallingfrog 4y agoNo, the world's people are not what has the input- the world's money does. Very different. Money does not think or feel, it's just a measure of power. Money is power. If you think money should purely decide this question you are in effect saying "whoever is the most powerful gets what they want", which is anti-civilization. Markets only function at all because powerful governments moderate and regulate them. Otherwise the world would quickly decay into a hobbsian war of all against all. Unregulated markets always self-destruct. Rationing on one level or another is the only reason that markets in limited areas are even possible. Try having markets without "rationing" who can print money, for example.
- WalterBright 4y ago> Unregulated markets always self-destruct. I hadn't noticed the US self-destructing. Maybe I read the wrong history books?
- fallingfrog 4y agoBecause our markets are tightly regulated. And where they aren’t you get things like the financial crisis.
