California Has Plenty of Water

Setting the Record Straight on California’s Water Supply Situation

I have 25 years of experience as a researcher and analyst in water resources. I know the history. I know the policies. I have seen the data. I know what I am talking about when it comes to water in California. The state has been prone to vicious battles over water and related false propaganda since long before I entered this field, but it seems to have reached a new high. When I started working in this field, it was a niche industry. The public did not think about water policy or water resources unless there was an incident to make it salient (e.g. if water bills skyrocketed or water failed to come out of the tap).

Water resources did come to the forefront of the public consciousness in 2015, when amid a severe and unrelenting drought and after calls for voluntary conservation failed, then-Governor Jerry Brown issued an executive order directing the California Water Resources Control Board to develop a mandatory conservation framework. I wrote an article about the extensive regulatory approach to deal with the drought in the Journal of Water and followed-on with a series about the unintended consequences of the mandatory conservation standards in the Hydrowonk Blog.

However, the recent dominance of water in the mind of the public is not due to implementation of a draconian policy or its impact. It was an ill-informed (read: false) statement by Donald Trump. I am not anti-Trump, but I’m not MAGA either. My interest lies with policy, and on the water policy thing he’s wrong.

On January 8, 2025, some fire hydrants in Pacific Palisades failed while firefighters were trying to battle a devasting wildfire. News reports showed an empty water tank in Palisades, and President-elect Donald Trump (President-elect because the inauguration had not yet happened) was quick to fire off an accusation that there was no water because of California Governor Gavin Newsom failed to sign a water restoration declaration.

Nothing about Trump’s statement was accurate. There was no water restoration declaration, and not because Newsom didn’t sign one. No such document had been proposed. That type of edict is contrary to the California Constitution and would be contrary to a complex set of state and federal laws governing water in California. The fire hydrants failed because of infrastructure limitations, not because of water supplies or water policies. California, and even Southern California, has plenty of water available, and it is flowing.

California Has Plenty of Water

Also on January 8, the California Data Exchange Center (CDEC), a website that reports telemetry readings from the reservoirs in the state, showed that we had 26.1 million acre-feet (or more than 8.5 trillion gallons) of water in storage, which is 122% the average amount of water in storage for the date. Looking at individual reservoirs, not just the collective statewide figures, most of the state’s reservoirs were at least 70% full and some quite a bit more than that. From an operational standpoint, that is full, maybe even over full, because of the capacity that should be left available for flood control purposes. Current figures (as of January 29), show the trend continuing. There is now 26.4 million acre-feet in storage, which is 117% of the average for the date. (The volume has increased, but the percent of the historical average has gone down because we usually have increase in storage due to winter storms during January). California is not out of water. In fact, the state has more water in storage than usual, and a lot of this is held in south-of-the-Delta reservoirs.

What about the empty tank in Palisades?

A social media troll accused me of spreading false information when I said that California has full reservoirs. He cited the empty tanks in Palisades that were shown all over the news. The problem with a non-expert is that they don’t know the vocabulary. While anything that holds a volume of liquid can technically be called a “reservoir,” there is a big difference between the water supply reservoirs I was referring to and the tanks that used as pressure regulators in the municipal water system in Palisades. The tanks, which each hold 1 million gallons (or about 3.07 acre-feet, which is a year's supply for about 6 families) ran dry because, under the extreme emergency situation, water was being pulled out of the system faster than it was being put in, so there was not enough pressure to move water to and through the hydrants.

California does have issues to resolve, but they lie in the sustainability of its water supplies, not in the current reliability. Strategies currently being used, expanded, or developed, include reuse, stormwater capture, conjunctive management (primarily using groundwater basins to store surface water), desalination, reducing demands, and developing new supplies where they exist.
