Idaho’s Snake River Closing Again this Week to Kill Quagga Mussel
A section of the Snake River near the City of Twin Falls will be closing after invasive Quagga Mussels were once again found in the water.
The river will be closed to the public for 10 days after the chemical treatment has been applied.
Snake River Closed Between Hansen Bridge and Centennial Park
The Idaho State Department of Agriculture announced today (Monday, October 7th) that a targeted Quagga Mussel treatment of Natrix, a chelated copper treatment, would begin on Tuesday, October 8th. The waterway between the Hansen Bridge and Centennial Waterfront Park will then be closed for 10 days.
Natrix is the same product used in 2023 to kill the invasive species. The treatment on Tuesday will be the first of 2 steps to kill the Quagga Mussels. The next treatment will happen in November and specifically target mussels in still water and deep sections of the river.
Water access along the Snake River has been limited for a while now in most places. The area above the Shoshone Falls never reopened after the first copper treatment and the Twin Falls Power Plant closed a few weeks ago for road, dock, and other repairs until 2025.
Access to Centennial Park Restricted for Road Work
In addition to the closure of the waterway, the road to Centennial Park will be closed for pavement repairs. According to KMVT, the construction project began today and should last through October 31st. Vehicle access to the park is expected to resume on November 1st.
