BLM studying metals in fish, insects near Red Devil Mine

On the Y-K Delta


The Bureau of Land Management is studying the concentrations of metals in fish and aquatic insects along the Kuskokwim River and several tributaries upstream and downstream of Red Devil Mine. The study covers non-salmon species that make up a large portion of the diet of subsistence users in the area.

During the summer and fall of 2010 and 2011, the Alaska Department of Fish and Game collected fish tissue samples for the BLM from adult northern pike, sheefish, burbot (or lush), Dolly Varden, and arctic grayling in the lower stretches of the George and Holitna rivers, in addition to 73 miles of the Kuskokwim River from Stony River to Crooked Creek.
