Built in 1937, this Earth-type dam stands at 27 feet in height and has a storage capacity of 360 acre-feet. The reservoir covers an area of 51.5 acres and is fed by Soldier Creek, with a maximum discharge capacity of 220 cubic feet per second. Despite its age, the dam has a low hazard potential and has not been rated for its condition.
Managed by the Oregon Water Resources Department, Deary Reservoir is subject to state regulations, inspections, and enforcement measures to ensure its safety and functionality. The dam site is located in a remote area near Rome, Oregon, and falls under the jurisdiction of the Sacramento District of the US Army Corps of Engineers. Although there have been no recent modifications or assessments of the dam's condition, its emergency action plan status, risk assessment, and management measures remain unspecified.
For water resource and climate enthusiasts, Deary Reservoir presents a unique example of historic dam infrastructure in Oregon. Its role in supporting agricultural irrigation in the region underscores the importance of maintaining and monitoring such structures for long-term sustainability. As a low-hazard facility, Deary Reservoir serves as a reminder of the ongoing need for responsible water resource management and emergency preparedness in the face of changing environmental conditions.
