Each dam contributes to a water resource management system that provides flood risk management, power generation, water quality improvement, irrigation, fish and wildlife habitat and recreation on the Columbia River and some of its tributaries.

 

There are many developed recreation sites along the Columbia River. Activities available at each area vary, but may include: camping, picnicking, boating, water skiing, fishing, swimming, hunting, hiking, biking, equestrian use and wildlife viewing.
