  • Watercraft Inspections

    • Idaho State Department of Agriculture.

    • Idaho's inspection stations are placed on major highways at or near the Idaho state line. The purpose of these stations is to inspect watercraft coming from outside of Idaho. Inspectors will look for high-risk boats that have been in quagga mussel and zebra mussel impacted states. Boats will be inspected for any attached mussels and/or standing water and owners also will be asked where they have boated in the previous 30 days. It is important that boaters arrive in Idaho with a clean, drained and dry watercraft.
