Quagga mussels were detected late in September in the Snake River, Shoshone Falls pool, and Pillar Falls. A copper treatment was applied in December by Idaho Fish and Game that did cause high mortality in some fish species.
The treatment is a 10-day operation starting at the downriver of Hansen Bridge to Centennial Waterfront Park. The treatment is the same product that was used in 2023, a copper-based product called, Natrix.
The ISDA is planning on continuing the treatment for a second time in November to target more quagga mussels still in the water.
