Montana watercraft inspection stations have intercepted 13 boats carrying invasive mollusks into the state this year. As of May 30, inspectors have caught 12 boats with invasive zebra or quagga mussels and one boat with red rim melania snails attached to watercraft.
Watercraft Inspection and Decontamination Programs
Many Western states instituted watercraft inspection and decontamination programs after the discovery of invasive mussels in Lake Mead in 2007 (Zook and Phillips 2012). As of 2018, nineteen states have implemented watercraft inspection and decontamination programs (Otts 2018).
This page contains resources on mandated watercraft inspection and decontamination programs, as well as some non-mandated but state-funded watercraft inspection efforts. This list below is not intended to be comprehensive, and all boaters should check with their relevant state agency before launching watercraft to ensure they comply with all regulations.

Idaho watercraft inspectors have identified zebra mussels on a commercially hauled sailboat destined for Lake Coeur d’Alene in the state’s northern panhandle, marking the first time the invasive species has been found live this year.
Building Consensus in the West: Developing a Model Legal Framework for Watercraft Inspection and Decontamination Programs
National Sea Grant Law Center.Initiative of the Western Regional Panel on Aquatic Nuisance Species (WRP). The goal of the WRP initiative is to develop a multi-state vision for watercraft inspection and decontamination (WID) programs. The National Sea Grant Law Center is an active participant in this initiative, providing legal research support and leading efforts to develop model legislation and regulations for WID Programs.

Pennsylvania Department of Conservation and Natural Resources.
Pennsylvania Department of Conservation and Natural Resources Secretary Cindy Adams Dunn announced that the department is launching an effort at nine state parks this summer to help prevent the spread of aquatic invasive species, and get boaters involved in invasive species detection. "Boats, motors, and trailers have ideal hiding spots where species may attach, and be transported to new locations," Dunn said. "Boaters must be involved in helping us protect state park waters from invaders, to benefit our environment and avoid very costly measures to treat lakes once these non-native species take hold." Starting this week, DCNR staff will be doing voluntary boat and trailer checks at boat launches on park lakes, handing out informational brochures and demonstrating how to do an inspection.

Beginning Jan. 1, 2020, the Aquatic Invasive Species (AIS) Permit required for non-motorized boats 10 feet and longer will be replaced by a Waterway Access Permit. The AIS Permit will remain for out-of-state motorized boats and is included in Oregon boat registration fees.
