Mercer is a vital water supply dam located in Dallas, Oregon, along the Rickreall Creek. Completed in 1961, this earth dam stands at 81 feet high and spans 460 feet in length, with a storage capacity of 1550 acre-feet. Despite its critical role in providing water to the region, Mercer has been flagged for its high hazard potential and poor condition assessment, requiring frequent inspections due to safety concerns.

Managed by the local government and regulated by the Oregon Water Resources Department, Mercer serves as a key source of water for the community. With a maximum discharge capacity of 8700 cubic feet per second and a drainage area of 17.8 square miles, this dam plays a crucial role in managing water resources in the area. However, its deteriorating condition and high hazard potential highlight the need for ongoing maintenance and risk management measures to ensure the safety and reliability of the dam.

As climate change continues to impact water resources and infrastructure, the importance of maintaining and upgrading dams like Mercer becomes increasingly crucial. With its strategic location in Polk County, Oregon, Mercer serves as a reminder of the intricate balance between water supply management and climate resilience. As water resource and climate enthusiasts, it is essential to monitor and support initiatives that promote sustainable water management practices and strengthen the resilience of critical infrastructure like Mercer for the benefit of future generations.
