Drews, located in Lake County, Oregon, is a privately owned irrigation dam on Drews Creek completed in 1914. With a height of 60 feet and a storage capacity of 65,000 acre-feet, this rockfill dam serves the crucial purpose of providing water for agriculture in the region. Despite being regulated by the Oregon Water Resources Department and inspected regularly, Drews has a high hazard potential due to its condition being assessed as fair.

The dam's structure, with a hydraulic height of 55 feet and a structural height of 63 feet, covers a surface area of 4754 acres and has a drainage area of 212 square miles. It boasts a maximum discharge capacity of 2900 cubic feet per second, making it a key component in managing water resources in the area. The dam is equipped with needle outlet gates, and its last inspection in August 2020 revealed an overall fair condition, prompting ongoing risk management measures to ensure its safety and functionality.

Managed by a private entity, Drews plays a critical role in the irrigation infrastructure of the region, supporting agricultural activities and water supply. As climate change continues to impact water resources, monitoring and maintaining the dam's integrity are vital for sustainable water management in Lake County, Oregon. With its historical significance and practical importance, Drews stands as a testament to the enduring value of water infrastructure in adapting to changing environmental conditions.
