Carty Reservoir, located in Arlington, Oregon, is a vital water resource managed by a public utility agency for irrigation purposes. Completed in 1976, this reservoir boasts an impressive dam height of 80 feet and a storage capacity of 150,000 acre-feet, providing essential water for agriculture in the region. With a surface area of 1450 acres and a drainage area of 65 square miles, Carty Reservoir plays a crucial role in water management along the Columbia River.

The reservoir's significant hazard potential underscores the importance of regular inspections and maintenance to ensure its structural integrity. Despite being classified as "Not Rated" in terms of condition assessment, the reservoir's emergency action plan and risk management measures are key aspects that need to be continually updated and improved. With a maximum discharge capacity of 22,000 cubic feet per second, Carty Reservoir holds immense potential in water resource management and climate resilience efforts in the region.

As a key water infrastructure project in Morrow County, Oregon, Carty Reservoir stands as a testament to the importance of sustainable water management practices. With its strategic location along the Columbia River and its critical role in irrigation, this reservoir serves as a cornerstone for agricultural activities in the area. Moving forward, continued investment in inspection, maintenance, and risk mitigation measures will be essential to ensure the long-term viability and safety of Carty Reservoir for generations to come.
