Built in 1937 for irrigation purposes, this earth dam stands at a height of 28 feet and has a length of 480 feet. With a storage capacity of 130 acre-feet and a maximum discharge of 250 cubic feet per second, the dam plays a significant role in managing water resources in the area.
Despite its importance, Blair Reservoir Dam has been assessed to be in poor condition with a high hazard potential. The dam is under the jurisdiction of the Washington Department of Ecology, which oversees its regulation, inspection, and enforcement. The last inspection in October 2021 revealed the dam's deteriorating condition, highlighting the urgent need for maintenance and risk management measures to ensure public safety and the continuous functioning of the reservoir.
As a vital structure in the Tri-Columbia River watershed, Blair Reservoir Dam faces challenges in maintaining its integrity and safety. With its poor condition and high hazard potential, there is a pressing need for investment in rehabilitation and maintenance efforts to safeguard the surrounding communities and water resources. Climate and water resource enthusiasts should monitor developments related to this dam to ensure sustainable management of this critical infrastructure in Washington state.
