About the lewis river
The Lewis River is located in southwestern Washington state and stretches 95 miles, originating from the western slopes of Mount Adams. Historically, the river was used by the Chinook Indians as a trading and fishing route. Today, it is primarily used for hydroelectric power and is managed by the Pacific Power and Light Company. The river is dammed in several locations, including the Merwin Dam, Yale Dam, and Swift Dam, which create reservoirs for power generation and recreational activities such as fishing, boating, and swimming. The river also supports agriculture in the region, with farms located along its banks producing crops such as berries and vegetables. The Lewis River remains an important resource for the community, providing power, recreation, and sustenance.
