Idaho River Talks: chinook salmon, arsenic and the South Fork of the Salmon River

  • Idaho River Sports (map)

In this month's Idaho River Talks lecture Caleb Zurstadt of the U.S. Forest Service and Austin Baldwin from the U.S. Geological Survey will present about their research as it pertains to the South Fork of the Salmon River. 

The South Fork of the Salmon's headwaters are high in the Salmon River Mountains east of Cascade, Idaho, at almost 8,000 feet. The river travels for approximately 86 miles to where it meets the main stem of the Salmon River just south of Mackay Bar. Legacy impacts from mining, road construction and logging are on the mend in this river basin. 

Zurstadt is a fisheries biologist for the Payette National Forest and is an expert about on the South Fork Salmon. He will discuss his research of legacy impacts on the river and what that means for endangered chinook and threatened bull trout. Austin Baldwin, a hydrologist, knows the water quality profile of the East Fork of the South Fork of the Salmon River intimately. Baldwin will highlight factors that stress the the East Fork and impact aquatic life locally and downstream.
