'A five-alarm fire': Western reservoirs that supply California fall to record low levels

Summary by The Los Angeles Editorial Desk · Based on reporting by Ian James, Los Angeles Times - California · July 21, 2026 · 1 min read

The Colorado River's largest reservoirs, Lake Mead and Lake Powell, have declined to the lowest combined levels on record. Researchers say this underscores the urgent need to cut water use.

Why this matters in The Los Angeles

The record low levels of Lake Mead and Lake Powell have significant implications for Los Angeles, which relies on the Colorado River for a substantial portion of its water supply. As the city's water management officials scramble to respond to the crisis, Angelenos can expect increased emphasis on conservation measures, such as restrictions on outdoor watering and incentives for installing low-flow appliances. The city's existing water-saving programs may also be expanded or strengthened in an effort to reduce demand on the dwindling Colorado River supply. With the region's hot and dry summer months approaching, the pressure to conserve water will only intensify, making it crucial for residents and businesses to take proactive steps to reduce their water usage and help mitigate the effects of this unprecedented drought.
