ALASKA RESERVOIR REPORT

Last Updated: March 13, 2026

As of the latest observations, Alaska’s dams and reservoirs are experiencing varied storage levels, with some areas affected by snow drought conditions. The 'Snow Drought Current Conditions and Impacts in the West' report from Drought.gov indicates that certain regions in Alaska have lower-than-average snowpack, which could lead to reduced inflows to reservoirs. However, this impact is not uniform across the state, as the weather forecasts from AOL.com around Christmas indicated significant snowfall in other parts of Alaska, which may have contributed positively to reservoir levels. It is crucial to note that snowpack levels are essential for spring and summer water supplies in reservoirs, as they act as natural storage that gradually releases water.

Cross-referencing with multiple sources, including the 'California and National Drought Summary' and the '10 Day Weather Outlook' from the Sierra Sun Times, as well as hydrological data from a specific March 12, 2026 blog update on coyotegulch.blog, it is apparent that while 14% of California is abnormally dry, Alaska’s reservoir storage levels have not been uniformly impacted. This discrepancy underscores the localized nature of weather patterns and their subsequent effects on water storage. Current storage measurements in Alaska’s key reservoirs such as the Eklutna Lake and Bradley Lake indicate that while storage levels are within the seasonal expectations, vigilance is necessary as the state progresses towards the drier months. As the spring thaw commences, these levels are expected to fluctuate, and continued monitoring will be essential to manage water resources effectively and prepare for any potential shortages due to the snow drought in affected areas.

Alaska has over 1,000 named lakes and reservoirs, with the largest ones being used for hydroelectric power generation, flood control, and water supply. The major reservoirs include Eklutna Lake, Chena Lake, and the Bradley Lake Reservoir, which are fed by glaciers, snowmelt, and several rivers and creeks. The snowpack in the mountains is a vital source of water, and the timing of its melting affects the streamflow and reservoir levels. The hydrology in the area is complex, with various geological formations and climatic patterns. Alaska has experienced record-high temperatures and drought conditions in recent years, leading to reduced water availability in some areas. However, the seasonal trends, such as the increased precipitation during the summer months and the snow accumulation during the winter, generally ensure sufficient water supply for the state's needs.
