The Willamette Valley Project

Map of the Willamette Valley Project

The Portland District operates 13 dams in the Willamette River basin. 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 Willamette River and many of its tributaries. 

For more information about a specific dam, click on its name on the map.

Since their completion, the dams have cumulatively prevented more than $20 billion in flood damages to the Willamette Valley. The Willamette River Basin is bounded by the Cascade Mountains on the east and the Coast Range on the west.

Although Corps dams only regulate about 27 percent of the water flowing into the Willamette River, our efforts help reduce flood damage in the Willamette River Basin, as well the North and South Santiam, McKenzie and Middle Fork Willamette river tributary basins.  

During the rainy season, potentially disastrous flooding is controlled by storing water in the reservoirs behind the dams. During the summer, water levels in the reservoirs are maintained as high as possible to provide water-related recreation opportunities. In the drier summer and fall months when rivers are at low levels, stored water is released from the dams to improve water quality and conditions for fish.  

Eight of the Willamette Valley dams generate hydroelectricity from the power of water passing through the dams. These dams can provide enough power to service about 300,000 homes.

Federal, state and local agencies and many Willamette Valley stakeholders are united in their commitment to protect native fish populations and their habitat. They have been working together for many years, along with private interests, on improvements essential for the successful protection and recovery of this Northwest treasure.  The Corps is a partner in efforts to revitalize our streams and habitats throughout the Willamette Valley.

There are more than 50 developed recreation sites within the Willamette Valley Project. Activities available at each reservoir vary, but may include: camping, picnicking, boating, water skiing, fishing, swimming, hunting, hiking, biking, equestrian use and wildlife viewing.
