As of March 2026, California's aging dams face a 'double whammy' of climate whiplash and structural decay.

Rapid swings from 'snow droughts' to massive atmospheric rivers are overwhelming 20th-century spillway designs.

The ASCE 2025 report card gave CA dams a D+, noting many are decades past their intended 50-year design life.

Following the 2017 crisis, Lake Oroville is monitored 24/7 as early snowmelt tests its restored spillways.

Whittier Narrows and Prado dams are labeled 'high urgency' due to potential collapse in extreme floods.

A failure at Folsom Dam would threaten downtown Sacramento, highlighting the high stakes for the state capital.

By March 2026, 20% of peak snowpack has already vanished due to record warmth, straining reservoir capacity.

Operators must dump water for flood safety even if it means less supply for summer. It's a high-stakes gamble.

Over 3,800 state properties sit in dam-failure inundation areas. Transparency and maps are now law.

Retrofitting aging dams costs billions. New projects like Sites Reservoir aim to provide safer storage.

As weather turns extreme, California must modernize its 'water bank' to ensure safety and survival.
