“There’s too little supply and too much demand,” said Brad Udall, a water and climate scientist at Colorado State University. “Ultimately, I think what we’re going to see here is some major rewriting of Western water law.”

“We’re seeing a collision right now between 19th century water law, 20th century infrastructure and 21st century population and climate change,” Udall added. “And how this works out is anybody’s guess.”

The snow and rain seen in the west this year isn’t enough to stabilize Lake Powell either, Andrechak said. “Now, the reality is, they’re all going to get a cut. Everybody should give,” he said.

“There’s no time left. The crisis is here. They don’t necessarily have to give it up forever. It might be temporary for several years until there’s improvements,” he said. But even if water levels do improve in the future, states cannot expect to return to former water usage entirely.

“Climate change is making sure that it’ll never get back to those levels,” Andrechak said.
