This earth dam, designed by URS Grenier Woodward-Clyde, stands at a hydraulic height of 61 feet and a structural height of 45 feet, completed in 1946. With a storage capacity of 5100 acre-feet and a normal storage of 4420 acre-feet, the dam plays a crucial role in supplying water to the surrounding areas.
Situated on the Tr-Skagit River, Judy Reservoir Dam A covers a surface area of 140 acres and has a drainage area of 1.5 square miles. Despite its satisfactory condition assessment, the dam is classified as having a high hazard potential, emphasizing the importance of regular inspections and maintenance. The last inspection conducted in January 2019 revealed no immediate concerns, with an inspection frequency of every 5 years to ensure the safety and stability of the structure.
With its significant contribution to water supply and the potential risks associated with its high hazard classification, Judy Reservoir Dam A stands as a critical infrastructure in the region. As water resource and climate enthusiasts, understanding and monitoring the condition of such dams is essential to ensure the resilience and sustainability of water systems in the face of changing climate patterns and environmental challenges.
