Social media users are playing the blame game when it comes to California鈥檚 drought. Read enough comments online and you鈥檒l see many similar responses blaming the state government for its management of water: California should have more water storage. California dumps water into the ocean. Northern California sends too much water to Southern California.
新澳门六合彩内幕信息 Davis experts said those assertions are incorrect.
鈥淭he characterization that this is just government malfeasance is wildly inaccurate and unfair, and misses the key points,鈥 said Richard Frank, professor of environmental practice and director of the California Environmental Law and Policy Center at the 新澳门六合彩内幕信息 Davis School of Law.
While some criticisms that appear frequently on social media have a basis in reality, others are completely untrue, Frank and other 新澳门六合彩内幕信息 Davis experts said.
They provided responses to common drought questions.

Why don鈥檛 we just build more dams?
Shouldn鈥檛 the state have seen the current drought coming and planned with more storage? Of course, more storage could help, but all the obvious places to build dams were turned into reservoirs years ago, Frank said. The state has more than 1,500 reservoirs, and each remaining additional option is more expensive and less effective than the last, he said.
Jay Lund, co-director for the Center for Watershed Sciences and a distinguished professor of civil and environmental engineering, agreed.
鈥淵ou can get some more water from building more reservoirs, but you don鈥檛 get much and it鈥檚 very expensive,鈥 Lund said.
Besides, none of that matters when the storage we do have is running dry (Lake Oroville, the state鈥檚 second-largest reservoir, ), so we should work harder to conserve, Frank said.
鈥淭here鈥檚 not enough water to fill the existing water infrastructure,鈥 he said. 鈥淚t鈥檚 not just a matter of readjusting expectations among water users 鈥 we have to redouble our efforts to conserve and use water more efficiently.鈥
He pointed to more efficient farm irrigation and drought-resistant urban landscaping as two possible ways to save more.
Are we dumping water into the ocean?
Then-president Donald Trump made headlines in October when he said the state was wasting countless gallons of water by dumping it into the Pacific Ocean 鈥渢o take care of certain little tiny fish.鈥
The state does release water into the Sacramento-San Joaquin Delta, an estuary where salt water from the sea mixes with fresh water from Sierra snowpack runoff. Water from the delta is used for irrigation and drinking water, and if too little freshwater is present, then seawater would fill the gaps.
鈥淚f you stopped allowing some fresh water to migrate, what you would have is salt water,鈥 Frank said. 鈥淭he water that is diverted would be salt water, and it would be unfit to drink and unfit to irrigate crops with.鈥
Water released into the delta also helps wildlife like endangered salmon, steelhead and others 鈥 but those animals are the first to suffer in a drought.
鈥淭his year most of the salmon stocks are going to perish and not be able to spawn,鈥 Frank said.
Karrigan B枚rk, an associate director at the Center for Watershed Sciences and an acting professor at the School of Law, said droughts can do quick and lasting damage to wildlife populations.
鈥淵ou can fallow a field for a year, but if fish are unsuccessful for a year, you can lose those populations pretty quickly,鈥 he said.
Lund said fish are likely suffering more than farmers and ranchers, who tend to have other options.
How can agriculture survive the drought?
California鈥檚 farmers and ranchers sold their products for more than in 2019, but all that output comes at a high cost to the state鈥檚 water supply 鈥 80 percent of all water use goes to ag, .
Lund said farmers and ranchers should reduce their irrigated footprint, swapping out less profitable crops like corn, cotton and wheat for more valuable ones like grapes or almonds.
鈥淚t鈥檚 going to be smaller in terms of acres, but it could easily be larger in terms of gross profits,鈥 he said. 鈥淲e鈥檙e still seeing a shift from low value crops to high value crops.鈥
A water marketplace could also help alleviate some of the tension between agricultural and urban water uses in the state, B枚rk said. Such a system would allow cities running low on water to 鈥渂uy鈥 water from farmers by paying them to leave fields fallow.
鈥淭hat could go a long way to mitigating problems in drought periods,鈥 he said.
One way or another, the agriculture industry will need to cut its water use, Frank said.
鈥淚 think what the [state] water board and most government regulators are saying is everybody is going to have to bear a share of the pain and cutbacks,鈥 he said. 鈥淔or those farmers and ranchers who think they have a right to the same level of water they used 20, 40, 50 years ago, they鈥檙e whistling past the graveyard.鈥
Is it Southern California鈥檚 fault?
In the blame game, Southern California 鈥 and large cities in general 鈥 are popular targets.
But again, the experts urged a look at the bigger picture.
鈥淵ou鈥檝e got to look at all the sectors in California,鈥 Frank said. 鈥淒omestic and urban use is considered the highest and best use of water [according to the law]. Are you going to tell cities they can鈥檛 provide water for their residents for cooking, cleaning and bathing? I don鈥檛 think so.鈥
B枚rk said the state could do a better job of setting expectations during good years, so people know where to make cuts once droughts hit.
Would desalination plants solve the drought?
Living in a coastal state beleaguered by drought might feel like 鈥渨ater, water everywhere, and not a drop to drink.鈥 So why don鈥檛 we use existing technology to remove the salt from the Pacific Ocean鈥檚 water? Some in Southern California are doing just that, , just 60 miles from the country鈥檚 largest facility.
That plant, which opened in Carlsbad in 2015, .
鈥淓ngineering-wise it鈥檚 quite possible, but it鈥檚 also very costly,鈥 Lund said. 鈥淭hat would essentially more than double most water bills in urban areas. 鈥 There might be some potential there, but it鈥檚 never going to be a big contributor, I think.鈥
He added that desalinated water would never be used for agriculture, because it would cost more than the price anyone could likely get for their crops.
Will we survive the drought?
Even as worsening droughts continue to threaten the state, California鈥檚 economy and people will be just fine, the experts said. that this state is one of the most prosperous Mediterranean climates in the world. (Australia鈥檚 gross domestic product per employed person is higher, but California produces more food.) Yet our native ecosystems haven鈥檛 suffered as much as those in other areas.
鈥淚 like to tell people we do a terrible job managing water, but if you grade on a curve we do pretty well,鈥 he said, adding that the main drivers of the economy 鈥 cities 鈥 are the parts of California best prepared to deal with droughts. He added that people in most other Mediterranean climates use much less water than Californians, so more lawns will likely have to turn brown here.
B枚rk said he is optimistic about the state鈥檚 water policy.
鈥淐alifornia has this long history of consistently, over time changing its water rights system to match the physical reality that鈥檚 facing the state,鈥 he said. 鈥淐alifornia has a remarkable ability to adapt, and I think we can find a way through this together.鈥
