a threat to idaho

September 2023 - The Idaho State Department of Agriculture confirmed the presence of quagga mussel veligers in the Mid-Snake River. The discovery of quagga mussel veligers in the Snake River marked the first time a rapid response plan had been put into action for quagga mussels in Idaho. 

The introduction of quagga mussels poses a major threat to Idaho. This invasive species can quickly spread and clog pipes that deliver water for drinking, energy, agriculture, recreation, and a variety of other uses. These mussels can negatively affect fish populations and wildlife habitat.

The mussels are highly competitive, persistent, and can create monocultures that will eliminate Idaho's diverse biological landscape. If left untreated, a quagga mussel infestation has the potential to cost Idaho hundreds of millions of dollars in actual and indirect costs. It could prompt increases in your taxes and bills.

Quagga mussels are primarily spread through human activities and have been done so unintentionally. Increased, travel, trade and tourism have contributed to the movement of quagga mussels across oceans and inter-state waterbodies; some species find their way accidentally by hitching a ride in, ballast tanks, inflatable watercrafts, cargo, or any items that come into contact with infested water.
