McNary Dam Fish Attraction Project - Hydroelectric Power Plant in the United States

McNary Dam Fish Attraction Project is a hydroelectric power plant located at McNary Dam on the Columbia River in the United States. With a capacity of 10 MW, it is a small-scale facility within the hydroelectric sector, primarily serving to attract fish to the dam's fish passage systems. The plant is owned and operated by Northern Wasco County PUD, a public utility district serving parts of Oregon and Washington. The plant operates under the regulatory framework of the Federal Energy Regulatory Commission (FERC) and must comply with the Clean Water Act and the Endangered Species Act, given its location on a major river system. Hydroelectric power in the Pacific Northwest is a significant energy source, with many dams providing both power and water management. The McNary Dam Fish Attraction Project uses a portion of the dam's flow to generate electricity while aiding fish migration. Environmentally, the project plays a dual role: generating renewable energy and supporting fish passage, which is critical for salmon and steelhead populations in the Columbia River basin. Its small capacity means a relatively low environmental footprint compared to larger hydroelectric facilities. The plant contributes to the regional grid's renewable energy mix and supports local ecosystem health.

The McNary Dam Fish Attraction Project operates in the Columbia River basin, a region with significant hydropower development and salmon migration routes. The facility's hydroelectric generation produces no direct air emissions, but its operation is tied to water flow management and fish passage. The plant's small capacity (10 MW) limits its ecological impact, while its fish attraction function helps mitigate the effects of the dam on local aquatic species.
