Which of the following lakes in Nevada requires high-risk inspection?

Lake Mohave requires high-risk inspection due to its status as a water body that is susceptible to aquatic invasive species (AIS). This lake has been identified as a critical area for monitoring because of its unique ecosystem and the presence of species that could be threatened by invasive organisms. High-risk inspections are typically mandated in areas where there is a higher likelihood of AIS introduction, which includes lakes with recreational activities such as boating and fishing, where boats can be transporting these harmful species.

In contrast, while other lakes like Lake Tahoe, Pyramid Lake, and Ruby Lake might also be significant in terms of environmental conservation and fishing, they may not have the same level of risk associated with AIS introduction as Lake Mohave does. The designation of "high-risk" typically reflects both the ecological vulnerability of the water body and the prevalence of recreational use that could facilitate the introduction of invasive species.
