The Idaho State Department of Agriculture announced on Apr. 14 that its watercraft inspection stations have begun operating for the 2026 season.
These inspections are important because they help prevent the spread of invasive species such as quagga and zebra mussels, which can harm Idaho’s waterways, economy, and wildlife. All boat owners traveling past an inspection station during operating hours are required by law to stop for a mandatory check.
“Stopping at watercraft inspection stations is a critical step in protecting Idaho from invasive species,” said ISDA Director Chanel Tewalt. “Idaho’s waters are essential to our recreation, economy and way of life. Whether coming from out of state or visiting a local waterway, we all share a responsibility to stop at inspection stations. Making the effort to clean, drain and dry all watercraft is essential to protecting Idaho.”
Idaho law requires that out-of-state boats be inspected and decontaminated before launching in state waters. Nonresident owners must also purchase an invasive species sticker prior to launching their craft in Idaho. Additionally, operators must remove drain plugs and empty all compartments holding water before transporting any vessel within the state.
The ISDA reported that more than 173,000 inspections were performed in 2025, with statewide inspections increasing by 67 percent since quagga mussels were detected in the Snake River in 2023. Infestations can lead to major impacts on fish populations, wildlife habitats, infrastructure damage, and significant costs.
The department supports community well-being by fostering economic opportunities through agricultural trade and development programs according to its official website. It also works to protect people, plants, animals and the environment through promotion, education and regulation efforts according to its official website. The agency has achieved notable results such as leading the largest eradication of Japanese beetles in U.S. history through cooperative work in Boise according to its official website.
Statewide services provided by ISDA bolster Idaho’s agricultural economy according to its official website, while more than sixty sections of state code related to agriculture are administered by the department according to its official website. The agency collaborates with federal organizations like USDA and EPA on programs including organic certification and pesticide regulation according to its official website.
