Idaho River Talks: water quality, mercury in Hells Canyon and Dry Creek redband trout survival

  • Idaho River Sports 601 North Whitewater Park Boulevard Boise, ID, 83702 United States (map)

The River Talk Series is back! In honor of Earth Month we will be focusing on clean water. Austin Baldwin from the U.S Geological Survey and Chris Walser, Biology Professor at College of Idaho and IRU Board Member will present their research as it pertains to water quality in Hells Canyon and Dry Creek.

Hells Canyon stretches 220 miles along the Idaho-Oregon border. This reach includes three reservoirs (Brownlee, Oxbow, and Hells Canyon). It also includes over 70 miles of the free-flowing Snake River upstream of the reservoir complex and nearly 60 miles of the free-flowing Snake River downstream of the reservoir complex. The downstream segment is designated under the Wild and Scenic Rivers Act and flows through the Hells Canyon Wilderness, the Hells Canyon National Recreation Area, and some of the deepest canyons in North America. It has seen its fair share of nutrient pollution problems and Austin Baldwin, a hydrologist, knows the water quality profile of Hells Canyon. Baldwin will present findings on mercury levels in Hells Canyon and its impact on aquatic life and downstream quality.

Dry Creek, a tributary to the Boise River, and a popular spot for redband trout has been under immense pressure in the summer months. Over the past six years Chris Walser has gotten to understand Dry Creek intimately as he and his students have been researching water quality (temperature and oxygen levels) in the summer months and how it affects redband trout survival.

Join us for a night of snacks, strong beverages and some truly fascinating research that affects the water quality of our rivers.
