During a high-risk inspection, which of the following would NOT require it?

The option indicating that a watercraft has been cleaned and stored indoors does not necessitate a high-risk inspection because the cleaning process generally removes any aquatic invasive species or their reproductive materials that could pose a risk to other water bodies. Storing the watercraft indoors further minimizes the chances of any possible contamination, as it prevents exposure to potential invasive species found in the environment.

In contrast, the other scenarios reflect circumstances that increase the risk of introducing or spreading invasive species. If a watercraft has traversed a high-risk waterbody, there’s a heightened chance of contamination from invasive species prevalent in those waters. Similarly, if biological material is found on the watercraft, it indicates a clear risk for transporting invasive species. Lastly, a watercraft with unknown last waters poses uncertainty about previous exposure, warranting a thorough inspection to ensure it is free of potential threats. Each of these conditions directly relates to the risk of spreading invasive species, which is why a high-risk inspection is deemed necessary in those instances.
