Hemlock Meadows Dam, located in Douglas County, Oregon, stands as a vital structure along Hemlock Creek, serving multiple purposes since its completion in 1962. Managed by the Oregon Department of Fish and Wildlife, this earth-type dam stands at a height of 61 feet and has a storage capacity of 1150 acre-feet. Despite its low hazard potential, the dam has a moderate risk assessment rating due to its condition not being rated and the lack of updated emergency action plans.
The dam's primary purpose remains listed as "Other", with a spillway type of "Uncontrolled", raising concerns about its ability to manage potential overflow events effectively. The presence of uncontrolled spillways coupled with its location in a state-regulated area under the Oregon Water Resources Department adds complexity to its risk management measures. With a drainage area of 0.7 square miles and a maximum discharge capacity of 180 cubic feet per second, the dam's role in regulating water flow and storage in the region is crucial for maintaining ecological balance and mitigating flood risks.
Engagement with the Hemlock Meadows Dam not only highlights the intersection of water resource management, climate resilience, and regulatory oversight but also underscores the need for updated inspections, assessments, and emergency preparedness protocols to ensure the safety and sustainability of this critical infrastructure in the face of evolving environmental challenges.
