ARKANSAS RESERVOIR REPORT

Last Updated: February 11, 2026

Across the nation, dams and reservoirs play a crucial role in water supply, agricultural irrigation, flood control, and recreation. Currently, there is a notable variance in storage levels, reflecting diverse hydrological conditions. For instance, Lake Powell, straddling Arizona, exhibits storage levels significantly below average, with current storage at 6,058,625 acre-ft compared to the historical average of 14,671,042.6 acre-ft, indicating potential water supply stress and hydroelectric power generation challenges. In contrast, Utah Lake in Utah is experiencing a surplus, with storage levels rising to 690,563 acre-ft from the average of 629,839.45 acre-ft. These variations are indicative of broader environmental patterns, such as precipitation, snowpack conditions, and river flows that feed into these critical water bodies.

On a more granular level, California's Lake Almanor and Lake San Antonio are above their historical storage averages, possibly a result of targeted conservation measures and above-average precipitation. Conversely, Colorado's Dillon, Granby, and Green Mountain reservoirs are all reporting storage below average, which may raise concerns about water availability for the upcoming dry season. Similarly, New Mexico's Heron and El Vado reservoirs are well below their average storage levels, pointing to ongoing drought conditions that could affect local water restrictions and management decisions. As hydrologists and water management experts continue to monitor these vital resources, the data underscores the importance of adaptive water management strategies to navigate the variability and challenges posed by changing climatic conditions.

Arkansas has numerous reservoirs and dams, with the White and Arkansas rivers being the major sources of water for these bodies. Some of the prominent reservoirs in the state include Lake Ouachita, Greers Ferry Lake, and Beaver Lake. These reservoirs are fed by several creeks and tributaries, and the water levels are largely influenced by factors such as rainfall, snowpack, and seasonal trends. The Ozark and Ouachita mountains are significant in the hydrology of the area and contribute to the snowpack that ultimately feeds the reservoirs. In recent years, Arkansas has experienced severe drought conditions, with record-low water levels reported in several reservoirs. Lake Ouachita, the largest reservoir in the state, has experienced severe drought conditions and reached record-low levels in recent years. The drought conditions have also impacted other reservoirs in the state, with Beaver Lake and Greers Ferry Lake experiencing lower-than-normal water levels. Overall, the hydrology of Arkansas is influenced by several factors, including rainfall, snowpack, and seasonal trends. The state has experienced both record-breaking highs and lows, with drought conditions being a significant concern in recent years.
