Salmon Endangered By Dams In Þjórsá River

Originally published by Reykjavík Grapevine

A plan to build three dams in the river Þjórsá could wipe out salmon in the river. National power company Landsvirkjun insist they have measures on the table to keep the salmon alive. Vísir reports that an environmental assessment has already confirmed that should the three proposed dams be built, the salmon that use the river will disappear.

Plans to dam Þjórsá have not been without their controversy, as the project has been heatedly debated for years now. In fact, the notion that damming up the river would wipe out salmon from the river was known as far back as 2002. While Landsvirkjun says they would construct what effectively amounts to a sperm bank for salmon to fertilise eggs, the Ministry for the Environment has looked at the plan and concluded that nothing in the plan indicates that it would even work.

The three dams have been green-lit, though, so the options now on the table are to either find some other way to save the river’s salmon while construction goes underway, or to pull the plug on construction, either temporarily or permanently. Neither option will be inexpensive for the parties involved.
