The public’s cooperation in staying out of the impacted area is crucial to the success of our efforts. Temporarily closing waterbodies is critical to responding to the situation and to minimizing any potential movement of quagga mussels.
current closure
Water access from Yingst Grade to Hansen Bridge is closed to public access (IDAPA 02.06.09.135). The public’s cooperation in staying out of the impacted area is crucial to the success of our efforts. Temporarily closing waterbodies is critical to responding to the situation and to minimizing any potential movement of quagga mussels.
Treatment dissipation area
Treatment dissipates immediately outside of the application area. Within this 18-mile dissipation area (Hansen Bridge to Kanaka Rapid), product will be present in the water for approximately three days after the final treatment application.
The treatment concluded on October 20th. The chelated copper has dissipated as anticipated and the river is expected to return to normal copper levels by early November.
It is not required by label, but out of an abundance of caution ISDA recommends keeping all pets, livestock, and people out of the river from below Hansen Bridge to Kanaka Rapid during active treatment. If you are a landowner along the river with questions about the treatment, please call (208) 332-8620.
