Reservoir Levels Weather Hydrology

Howard A Hanson Reservoir, located in Washington State near Palmer, is a large water storage reservoir that was constructed in the 1960s for flood control, water supply, and hydroelectric power generation. The reservoir is fed by several major creeks and rivers, including the Green River and its tributaries. The surface flow of the reservoir is primarily from the Green River, which provides over 80% of the water volume. The reservoir also receives water from snowpack, which contributes to the reservoir's water levels during the spring and early summer. The reservoir has been used for agricultural irrigation and recreation, including fishing, boating, and camping. However, in recent years, the reservoir has faced problems with sediment buildup, water quality issues, and potential dam safety concerns.
