Gold was discovered in the later 1800’s<br />
in the upper Koyukuk Drainage. The US<br />
Bureau of Land Management is currently<br />
conducting two reclamation projects in<br />
the drainage. The Gold Bench and<br />
Ironside are located in the upper<br />
reaches of the drainage.<br />
Other impacts to the drainage include<br />
the LRRS at Indian Mountain, FUDS<br />
locations, petroleum spills and historic<br />
mining. The Trans-Alaska Pipeline<br />
