OKLAHOMA RESERVOIR REPORT

Last Updated: December 19, 2025

In a comprehensive overview of the nation's dams and reservoirs, the latest observations reveal a diverse array of storage levels, with some water bodies experiencing surpluses and others facing drought-like conditions. Notably, Lake Mead in Nevada and Lake Powell in Arizona are significantly below their average storage levels, reflecting the ongoing water scarcity challenges in the southwestern United States. Conversely, reservoirs such as Lake Almanor and New Bullards Bar in California are reporting storage levels above average, indicating a surplus that benefits local water supply and ecosystem management.

Diving deeper into specifics, Colorado's Blue Mesa Reservoir and New Mexico's Elephant Butte Reservoir are experiencing low storage levels compared to historical averages, underscoring the impact of prolonged drought and climate variability in these regions. On the other hand, reservoirs like California's Lake Almanor and New Bullards Bar have seen an increase in storage, likely influenced by recent precipitation events that have somewhat alleviated the water stress in their respective watersheds. These insights reflect the complex and dynamic nature of water resource management, as hydrologists and researchers work to balance ecological needs with human consumption, agricultural demands, and the challenges posed by changing climatic conditions.

Oklahoma has numerous reservoirs and dams, with the largest being Lake Texoma on the Red River. Other major reservoirs include Lake Eufaula, Lake Tenkiller, and Keystone Lake. These reservoirs are fed by various streams, rivers, and creeks, with many of them originating in the surrounding mountains of the Ozarks and Ouachitas. Snowpack is not a significant contributor to the water supply in Oklahoma, as the state typically receives little snowfall. Drought conditions are common in Oklahoma, with some reservoirs experiencing record low levels during prolonged dry spells. Seasonal trends show varying levels of precipitation and streamflow throughout the year, with the highest levels typically occurring in the spring and early summer. Overall, the hydrology of Oklahoma is heavily influenced by precipitation patterns and the unique geology of the region, with reservoirs and dams serving as crucial components of water management and conservation efforts.
