Woodrat Knob is a private irrigation dam located in Lake Creek, Oregon. Completed in 1960, this earth dam stands at a height of 90 feet and has a storage capacity of 1,789 acre-feet. It primarily serves the purpose of irrigation for the surrounding area, drawing water from Lake Creek and its tributaries.

Despite its vital role in water resource management, Woodrat Knob poses a high hazard potential due to its unsatisfactory condition assessment. The dam is equipped with a slide gate as its outlet structure and an uncontrolled spillway type. Regular inspections are conducted to ensure the safety and integrity of the structure, with the last inspection taking place in July 2021.

With a moderate risk assessment rating of 3, Woodrat Knob requires ongoing risk management measures to mitigate potential hazards. Its location in a picturesque setting in Jackson County, Oregon, makes it a focal point for water resource and climate enthusiasts interested in the intersection of infrastructure, sustainability, and environmental stewardship.
