As a result, 95,000 tons of sediment flowed into the river for six years year until environmentalists, government entities and mining companies stopped the breach.
I suspect contractors hired by the mining companies actually stopped the breach while the govt and environmental groups stood in the way.
There will be 17 million yards of sediment sent down the Klamath if the dams are breached. Thats about enough
to cover I5 from Hornbrook to San Diego with about 2 feet
of sediment.
