Dams protected Columbia River from negative impacts of climate change

This is a study that anti-dam organizations won’t tell you about. Because it weakens most of their critics portraying dams as powerful agents of river destruction.

That study suggests on the contrary that large dams provide “ecological and engineering resilience” to climate change in the Columbia River basin.

Oroville Dam, ICOLD President intervenes on the radio

Oroville Dam, ICOLD President intervenes on the radio

There is now a rush to repair the spillways at the Oroville Dam in Northern California and lower the water level in Lake Oroville before rain arrives again. It is feared that damage to an emergency spillway could dump large amounts of water into the Feather River, which runs through downtown Oroville. This fear led to the evacuation of nearly 200 000 people living under the lake. The main dam (235m high) was never in danger and remains safe. The Oroville Dam issue started with an unexplained structural failure of a lower part of the 3000-foot-long gated service spillway.
