Osborne Creek, also known as Cascade Ranch #, is a private water resource located in Jackson County, Oregon. This earth dam, completed in 1964, serves primarily for irrigation purposes and stands at a height of 60 feet with a hydraulic height of 56 feet. The dam has a storage capacity of 775 acre-feet and covers a surface area of 35.4 acres, drawing water from a drainage area of 3.25 square miles.

Despite its essential role in providing water for agriculture, Osborne Creek's dam is rated as having a high hazard potential with a poor condition assessment. The last inspection in July 2021 highlighted its need for maintenance and repairs. The outlet gates consist of a slide (sluice gate) design, and the dam is regulated by the Oregon Water Resources Department, with permitting, inspection, and enforcement processes in place to ensure its safety and compliance with regulations.

Located in Brownsboro, Oregon, Osborne Creek's dam serves as a critical infrastructure for water management in the region. As climate change continues to impact water resources, the maintenance and improvement of structures like Osborne Creek are crucial for sustainable water use and resilience to changing environmental conditions. Efforts to address the dam's maintenance needs and mitigate potential risks are essential to safeguarding this important water resource for the community and the environment.
