In the Sierra Nevada mountains, the transition from winter to spring is usually a gradual melt. But this year, the process was violent. By April 1, the California Department of Water Resources (DWR) found no measurable snow at a Phillips Station survey site where more than two feet of snow had stood just weeks earlier in late February.
A record-breaking hot and dry March effectively sizzled away the snowpack, leaving behind a landscape of mud and grass. The rapid disappearance of this “frozen reservoir” has raised immediate questions about the state’s water security and whether the region is sliding back into a period of severe scarcity.
The sudden shift has left state officials cautious. Speaking at the snow survey, DWR Director Karla Nemeth questioned whether the state is entering a new hydrologic drought. “The answer is, I don’t know,” Nemeth said. “We could be . . . We’ll know with more clarity next year if this year in fact is the start of a hydrologic drought in California and throughout the West.”
Despite the uncertainty, the state is operating with a different playbook than it did a decade ago. California is now implementing a comprehensive strategy to mitigate the impact of record heat and dwindling snow, combining aggressive infrastructure investment with new legal mandates to protect the most vulnerable water systems.

Building Resilience After Decades of Crisis
California’s current readiness is a direct response to a brutal history of precipitation deficits. The state endured five consecutive dry years from 2012 to 2016, followed by its driest consecutive three-year period on record between 2020 and 2022. These crises exposed critical failures in the state’s water grid, particularly in rural areas where private wells and small-scale systems often failed first.
To address these gaps, the state has shifted from reactive emergency management to proactive resilience. Large urban water districts have already spent decades diversifying their supply sources and expanding storage, allowing most city dwellers to weather dry spells without major service disruptions. However, the focus has recently shifted toward the “disadvantaged communities” that historically bore the brunt of drought impacts.
Since 2019, the State Water Resources Control Board has utilized the Safe and Affordable Funding for Equity and Resilience (SAFER) program to distribute over $1.8 billion in grants. These funds are earmarked for bringing safe drinking water to small, marginalized communities. The impact is measurable: the number of Californians lacking access to safe and affordable water has dropped from an estimated 1.6 million in 2019 to fewer than 600,000 today.
Beyond funding, the state has focused on structural stability. More than 170 water system consolidations have been completed, successfully connecting over 360,000 people to more reliable, professionalized water networks.
Legislative Guardrails and Groundwater Management
In 2021, the California Legislature and Governor enacted a law specifically designed to eliminate the “surprise” element of drought. The legislation mandates that water suppliers with fewer than 3,000 connections must maintain a water shortage contingency plan and report their supply conditions and usage monthly. This ensures that small-scale providers are no longer invisible to state planners until their wells run dry.
At the county level, new requirements demand interim and long-term solutions for the highest-risk systems—those with only five to 14 service connections and individual household wells. To support this, the DWR developed the Water Shortage Vulnerability Tool and established the DRIP Collaborative, an interagency task force that monitors drought indicators and defines the roles of state agencies in protecting household wells.
Perhaps the most significant long-term shift is the implementation of the Sustainable Groundwater Management Act (SGMA). Passed in 2014, SGMA requires local agencies to bring groundwater basins into sustainable conditions. By preventing the over-extraction of aquifers, the state is essentially treating groundwater as a “savings account” that can be drawn upon during years when the Sierra snowpack fails to materialize.
| Program/Law | Primary Objective | Key Metric/Impact |
|---|---|---|
| SAFER Program | Safe water for disadvantaged areas | $1.8B+ in grants since 2019 |
| 2021 Drought Law | Mandatory contingency planning | Required plans for <3,000 connections |
| SGMA (2014) | Groundwater sustainability | Restoring basins to sustainable levels |
| DWR Relief Funds | Infrastructure rehabilitation | $1B+ distributed in 2020-2021 |
Infrastructure for an Unpredictable Future
While policy and grants address the human element, the DWR is also altering how it manages the State Water Project to hedge against volatility. Since 2019, the agency has increased “carryover storage” in Lake Oroville. By holding back more water each summer, the state creates a buffer that can be deployed if the following year is dry.
Looking further ahead, California is pursuing larger-scale engineering projects to capture water during the “atmospheric river” events that often precede record heat. The Delta Conveyance Project aims to improve the movement of water into storage during high-flow periods. Simultaneously, local districts are investing in the proposed Sites reservoir to bolster their own drought-year reserves.
The stakes for these investments remain high. History shows that consecutive dry years do more than just empty reservoirs; they interrupt surface water deliveries to farms, threaten agricultural jobs, imperil fish and wildlife habitats, and create the tinder-box conditions that fuel catastrophic wildfires.
For those tracking the current state of the region’s aquifers and the progress of basin management, the DWR has released a comprehensive new resource, California’s Groundwater, which details the implementation of SGMA and current basin conditions.
The next critical checkpoint for the state will be the 2027 snow survey and hydrologic analysis, which will determine if the current lack of snow was an isolated anomaly or the definitive start of a multi-year hydrologic drought.
