A proposed gold and copper mine at the headwaters of the world's largest sockeye salmon fishery in Alaska would cause "unavoidable adverse impacts," the U.S. Army Corps of Engineers said in a letter to the developer released Monday, Aug. 24, 2020. The corps is asking the backers of Pebble Mine to come up with a mitigation plan within 90 days for nearly 3,000 acres of land and nearly 200 miles of streams it says could be affected if the controversial mine moves forward.

This Sunday, Sept. 8, 2019 photo provided by the U.S. Army Corps of Engineers shows a boat lock on the Bonneville Dam on the Columbia River that connects Oregon and Washington at Cascade Locks., Ore.
