But because of the prioritization of fish above people. The infrastructure needed to support people, never got built (theDailySignal):
Even now, in the Sierra foothills, state officials empty reservoirs to protect “unimpeded” river flows to benefit small numbers of non-endangered hatchery fish. The California Coastal Commission, the powerful agency with control of development along the shoreline, is holding up a privately planned desalination plant over concerns about its impact on plankton. The environment-friendly commission want to force the developers to build a pumping system that destroys the economics of the plant.
[...] Even the federal government is in on the action. In the far northern part of the state, along the Klamath River, federal environment officials want to remove four dams that provide water storage near the Oregon border. Their goal is to help preserve the habitat of non-native salmon. The “destroy the dams” movement had gained so much steam in recent years that San Franciscans were asked in a 2012 advisory vote to destroy the O’Shaughnessy dam in Yosemite National Park and drain the Hetch Hetchy Reservoir—the main source of water for the state’s third-largest city. Even that city’s notoriously lefty voters said “no” to shutting their main water spigot.
[...] Recent reports showed that farmers use 80 percent of California’s water resources. It’s true that farmers are an important interest group. And because of the state’s old and quirky system of water rights, we see infuriating misuses of resources—e.g., farmers growing water-intensive hay in one of the driest regions on Earth, the southern Imperial Valley.
But that 80 percent number was deceptive because it completely omitted environmental uses of water, which constitute more than 50 percent of the state’s flows. Farmers, businesses, and residents fight over what remains. What we’re seeing—water releases to benefit a small number of common fish, removing dams along major rivers, delays of desalination plants, failure to build adequate water storage—is not an anomaly. It is the cumulative effect of water policies dominated by environmental interests.
