OKLAHOMA RESERVOIR REPORT

Last Updated: December 25, 2025

Amidst the complex network of water bodies that sustain life and agriculture across the United States, the current landscape of reservoirs and dams presents a mixed tapestry of storage levels. As we delve into the latest observations, we witness a panorama of surfeit and deficit, each body of water narrating its own story of plenitude or paucity.

A closer look reveals that significant variances in storage measures exist, some reservoirs brimming over average capacity while others languish below. For instance, Lake Almanor in California is currently holding water volumes well above its historical average, providing a buffer against potential dry spells. Conversely, Elephant Butte Reservoir in New Mexico holds significantly less than its average storage, reflecting concerns of drought and water scarcity. These conditions may be influenced by a variety of factors, including regional precipitation patterns, water management practices, and the resultant impact on local ecosystems and communities.

On the other end of the spectrum, Colorado's Granby Reservoir showcases an uptick in storage, hinting at healthy snowpack contributions or efficient water management. However, the narrative alters starkly in the same state, where Vega Reservoir's storage levels have plummeted, potentially signaling alarm for downstream water needs. Similarly, in Utah, the Willard Bay Reservoir's storage levels have diminished, indicating possible implications for agricultural irrigation and urban water supplies in the region.

This intricate web of water bodies across states is a testament to the variability inherent in hydrological systems and the importance of strategic water management. As researchers and hydrologists monitor these vital resources, the dance between natural forces and human influence continues to shape the fluid story of the nation's dams and reservoirs.

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.
