A small gold permit, on a river fighting for its future

A single small mining permit filed last month is a window into a bigger fight over one of Alaska's most important salmon rivers.

Go Gulch Mining LLC has applied to run a mechanical placer gold operation at Gopher Gulch, a tributary that drains into the Susitna system. On its own, it's a routine filing — one of several placer applications that surface in the Yentna Mining District most years, reviewed under existing state and federal permits meant to limit the damage.

The Susitna supports Chinook, coho, and sockeye salmon that feed both sport fishing and Alaska Native subsistence, and much of the surrounding watershed is currently roadless.

That's the backdrop to a live debate over the proposed West Susitna Access Road, a roughly 100-mile industrial road the state and private developers have pushed to open the area to mining and other resource development. Supporters see it as unlocking jobs and Alaska's mineral wealth in a region that has long had gold and coal in the ground; opponents, including some tribal governments and subsistence users, worry about the effect of expanded mining and traffic on salmon streams.

The specific concerns raised in past Yentna District proceedings are familiar: sediment in salmon streams, diverted channels, and access impacts. Proponents argue those are manageable under state Fish and Game stipulations and the federal Clean Water Act permit governing this type of mining.

State agencies are reviewing the Gopher Gulch application now, with a short public-comment window open.
