This earth dam, with a hydraulic height of 18 feet and a structural height of 17.5 feet, stands on a foundation of rock and soil. The dam has a storage capacity of 578 acre-feet, with a normal storage level of 360 acre-feet, covering a surface area of 40 acres and draining a 5-square mile watershed.
Despite its age, Meadow Lake Dam is considered to have a high hazard potential and a poor condition assessment as of the last inspection in July 2017. The dam is state-regulated by the Washington Department of Ecology, with regular inspections mandated. The surrounding area offers recreational opportunities in addition to its vital role in irrigation, making it an essential structure in the region's water resource management. However, its poor condition highlights the importance of ongoing maintenance and potential updates to ensure the safety and efficiency of this key infrastructure.
