Winchester is a public utility located in the city of Winchester, Oregon, along the North Umpqua River. This dam, with a height of 17 feet and a length of 485 feet, was completed in 1904 for the primary purpose of recreation. The dam has a storage capacity of 700 acre-feet and covers a surface area of 27 acres, serving as a popular spot for outdoor activities.

Despite its recreational benefits, Winchester Dam is classified as having a high hazard potential and is currently in poor condition. The last inspection in July 2021 revealed the dam's deteriorating state, prompting concerns for its structural integrity and safety. With a designated inspection frequency of once per year, ongoing monitoring and maintenance are crucial to mitigate potential risks associated with the dam.

Managed by the Oregon Water Resources Department, Winchester Dam plays a significant role in the local water resource management and climate regulation efforts. As climate change continues to impact water availability and quality, the maintenance and upkeep of dams like Winchester are essential in ensuring the sustainability and resilience of water resources for future generations.
