The dam stands at a height of 90 feet and has a maximum storage capacity of 800 acre-feet, with a normal storage level of 700 acre-feet. The dam regulates the flow of Bear Creek, a 3.2 square mile drainage area, with a maximum discharge of 530 cubic feet per second.
Despite its critical role in water supply, Bear Creek Dam has a high hazard potential and poor condition assessment, highlighting the need for maintenance and potential upgrades to ensure its long-term safety and efficiency. The dam is owned by the local government and falls under state jurisdiction for regulation, permitting, inspection, and enforcement. The last inspection in November 2021 revealed its poor condition, prompting further assessment and potential risk management measures to be considered.
Located in the scenic city of Svensen, Bear Creek Dam serves as a vital infrastructure for water resource management in the region. With its historical significance and crucial role in providing water supply, safeguarding the dam's integrity and improving its condition will be essential for ensuring the continued resilience of the water system in Clatsop County, Oregon.
