A wet Sierra Nevada snowpack, full reservoirs, and a Fresno County supervisor saying flatly that California is not in a drought. That's the setup for a KMPH report this week, in which Supervisor Bianco argues the state's ongoing water shortages are a product of policy choices — export rules, environmental flow requirements, infrastructure decisions — not a lack of precipitation.

You can agree or disagree with his politics. But the household-level implication is the same either way: California water availability can tighten even in good rainfall years. If your preparedness plan assumes shortages only happen during droughts, your plan has a gap.

What's actually changing

The Central Valley and much of Southern California have operated for decades under a water system that moves supply from where it falls (the Sierra and the Sacramento-San Joaquin Delta) to where people live and farm. That system is governed by a dense web of water rights, state and federal environmental rules, and aging conveyance infrastructure. The Oroville Dam spillway failure in 2017 was a reminder that infrastructure stress can cut off delivery even when the water physically exists.

What Bianco's remarks point to is a structural vulnerability that doesn't track neatly with weather. Regulatory constraints on pumping at the Delta, court-ordered environmental flows, and disputes between the State Water Resources Control Board and agricultural water districts mean that even in above-average precipitation years, delivered water can be short. For California households — particularly in the San Joaquin Valley, the Inland Empire, and parts of Los Angeles County served by the Metropolitan Water District — this creates a preparedness problem that weather apps won't warn you about.

The honest caveat: water policy in California is genuinely contested. Scientists, engineers, and water managers disagree on how much current policy costs in deliverable supply versus how much is simply constrained by physical limits. We're not adjudicating that. We're noting that the gap between water-in-the-state and water-at-your-tap is real and not shrinking.

What we'd actually do

Know which water district or agency serves your address. Most California households receive water from a local municipal utility, a special district, or a private water company — each with different supply portfolios and reliability profiles. Look up your provider at the California State Water Resources Control Board's drinking water database. Some smaller districts in the Central Valley and rural foothill communities are on systems that have failed before.

Understanding your supplier tells you whether your water comes primarily from groundwater (more stable in the short term, but overdrafted in many basins), state water project deliveries (subject to the policy constraints Bianco is describing), or local surface water. That distinction shapes what kind of disruption is most plausible for your address.

Store two weeks of drinking water, not 72 hours. FEMA's three-day standard is a floor, not a plan. The California Department of Public Health recommends one gallon per person per day for drinking and sanitation. A household of four needs roughly 56 gallons for two weeks. Food-grade 5-gallon jugs stored in a cool, dark location and rotated every six to twelve months cost under $10 each at most hardware stores. This is the least glamorous prep on this list. It is also the one that will actually matter.

Learn where your home's main shutoff is and test it. If a water main breaks in your neighborhood or your district implements emergency shutoff rotations, you need to be able to isolate your home's plumbing quickly to prevent backflow contamination. Find the shutoff, confirm it turns, and make sure every adult in your household knows where it is. This takes ten minutes.

If you have a water heater, know how to use it as an emergency reserve. A standard 40- to 50-gallon tank water heater holds potable water that most households don't think about. In a supply interruption, that water is accessible via the drain valve at the base of the unit. The water must be treated before drinking if the heater has been off for more than a day or two, but it is a meaningful emergency buffer. Learn the procedure before you need it.

The bigger picture

California's water infrastructure was built for a version of the state that no longer exists — smaller population, different regulatory framework, different climate patterns. The system is being renegotiated in real time through the courts, the legislature, and agencies like the State Water Board. That process will take years, and its outcome is not certain.

Your household doesn't need to resolve that debate. You need enough stored water to get through a disruption, enough information to understand your local supply, and a basic physical understanding of your own plumbing. That's durable preparedness. It's not exciting. It works.
