AL00494-HERMAN-GIBSON-NO-2 RESERVOIR REPORT

Last Updated: January 27, 2026

Across the nation, a comprehensive dataset of the latest observations reveals that water storage levels in dams and reservoirs exhibit a tapestry of conditions, ranging from surpluses to concerning droughts. Major water bodies like Lake Powell in Arizona and Lake Mead in Nevada are reporting storage levels significantly below average, showcasing the stark reality of prolonged drought conditions in the Southwest. Conversely, reservoirs such as Lake San Antonio in California and Lake Texoma near Oklahoma have experienced surges in their water storage, reflecting above-average inflows and potentially favorable hydrological conditions.

The fluctuations in reservoir and dam storage levels are intricately linked to a variety of factors, including regional precipitation patterns, snowpack melt rates, and river flows. For instance, the substantial deficit at Lake Powell — currently at about 42% of its average storage — can be tied to reduced Colorado River flows and below-average snowpack in previous seasons. In contrast, northern reservoirs like Lake Almanor in California are experiencing higher-than-usual storage, possibly due to abundant snowfall in the Sierra Nevada Mountains enhancing the spring meltwater influx. These varying conditions across the country not only have significant implications for water availability and management but also highlight the need for adaptive strategies to cope with the challenges posed by climate variability and change.
