Although identified as NW Region actions regarding Federal Energy Regulatory Commission Licenses, this map gives an idea of the many dams on both large rivers and small streams in the Pacific Northwest. There are nearly twenty major dams on the Columbia River and Snake River shown here and at least 100 smaller sites shown.

Graphic showing the decimation of the salmonid population between 1850 and 1986 in the Columbia River Basin.

1980's graphic showing the extent of driftnet fisheries on the high seas of the North Pacific Ocean. This fishery indiscrimately caught numerous species contributed to the loss of salmon stock in the Pacific Northwest.

Water for irrigation requires dams and also reduces stream flow contributing to degradation of salmon habitat.
