Even if you don’t pay attention to the news, you’re probably aware that Los Angeles has been unusually dry for the past few years. If you do follow the news, you may have heard that right now California’s snowpacks are well below their 20th century average. And if you really pay attention to this stuff, you probably saw the news that the past 22-year period is the driest the American West has experienced in over a millennium.
Scary stuff. And as the impacts of climate change grow more pronounced, there’s a good chance things will get even scarier. Since it doesn’t seem likely that government officials or the public at large are going to make any real progress in cutting back on fossil fuels, the weird weather we’ve been seeing for the past couple decades is likely to get a whole lot weirder.
So what can we do? Well, the first thing we should do is stop lying to ourselves about how much water we have access to. A recent study from UC Davis shows that water rights allocations to California’s water users are about five times the state’s annual runoff. In other words, we’ve promised to deliver about five times more water than we actually have.
How did this happen? Well, back in the 20th century, when everyone was convinced that California was going to keep growing forever and that we had endless supplies of everything, Federal, State and regional agencies built a ridiculous number of dams and canals to deliver lots of water to everyone who wanted it. Two decades into the 21st century, it should be clear to all of us that we can’t keep growing forever and that our resources are definitely limited.
CalMatters recently ran an excellent piece by Carolee Krieger, Executive Director of California Water Impact Network, where Krieger clearly states the most important takeaway from the UC Davis report: We have to manage our water resources based on the amount of water that’s actually available. Here’s the link to Krieger’s article.
California faces huge challenges in meeting its future water needs. The first step is to be honest about how much water we actually have. Let’s stop pretending. It’s time to get real.
