The flow of the river is influenced by several factors including snowmelt, precipitation, and dam releases. The Klamath River has several tributaries, including the Shasta River, which provides additional water flow. However, dams on the river can impact the flow and temperature of the water, affecting fish populations. Seasonal trends show that the river tends to have higher flows during the spring and lower flows during the summer months. A unique feature of the Klamath River is its role in the local economy, supporting agriculture, fishing, and recreation.
