watercraft inspections

Watercraft Inspection Stations are Idaho’s first-line of defense against the introduction and spread of aquatic invasive species (AIS). Overland travel of contaminated watercraft and equipment is believed to be the single largest vector for AIS movement from one water system to the next. 

Inspection Stations

Idaho’s inspection stations are placed on major highways at or near the Idaho state line. This strategy is taken to maximize contact with boats that are traveling into the state from other impacted states.

High-Risk Watercraft Inspections

High-risk inspections are intense and include a thorough inspection of the exterior and interior parts of the boat. The inspection includes a thorough and complete visual and tactile inspection of all portions of the boat, including compartments, bilge, trailer and any equipment, gear, ropes or anchors.

If any biological material is found on the boat or equipment, the inspectors conduct a roadside “hotwash” of the watercraft. This is done to prevent the spread of other invasive species such as New Zealand mudsnail, Eurasian watermilfoil, and hydrilla.

More than 400,000 inspections have been conducted in Idaho under this program since 2009. Through these inspections, 165 mussel-fouled boats have been intercepted in Idaho since July of 2009.

Boats Considered “High-risk” to the state of Idaho

  • Boats that have been in mussel-infested states recently (within the last 30 days).
  • Watercraft coming from another state (especially commercially hauled boats).
  • Boats that show a lot of dirt, grime, or slime below the waterline.
  • Boats that have standing water on board.

2017 Inspection Station Information

The 2017 boating season has started, and inspection stations are now opening throughout the state. Below is a list of the stations for 2017 with some basic information that will be collected during the season.

In addition to the listed inspection station locations, watercraft are inspected during the boating season at roving roadside inspection stations spread throughout the state. These additional inspections help ISDA better understand the boating public, and potential vectors of introduction into Idaho.
