Slide Creek is a hydroelectric dam located in Douglas, Oregon, along the North Umpqua River. Built in 1951, the dam stands at 30 feet tall with a gravity design and a multi-arch core type. It serves the primary purpose of hydroelectric power generation and has a storage capacity of 43 acre-feet with a maximum discharge of 15,000 cubic feet per second. The dam features a controlled spillway with a width of 92 feet and two Tainter (radial) outlet gates.

Managed by the Federal Energy Regulatory Commission, Slide Creek has a low hazard potential and a very high risk assessment rating. Despite not having a recent condition assessment available, the dam undergoes inspections every three years to ensure its structural integrity and safety. While the dam is not state-regulated, it is crucial for providing renewable energy to the region and managing the flow of the North Umpqua River. For water resource and climate enthusiasts, Slide Creek presents an intriguing blend of engineering marvel and environmental impact within the picturesque landscape of Oregon.
