The Columbia River is the primary flow provider, but there are also several smaller tributaries that contribute to the overall flow. The Dalles Dam, which was completed in 1957, regulates the flow of water and generates hydroelectric power. Seasonal trends in flow are influenced by snowmelt and rainfall, with the highest flows occurring in the spring and early summer. Interesting facts about the hydrology of the Columbia River at The Dalles include the presence of salmon runs and the historic use of the river as a transportation route by Native American tribes.
