Is it possible for bull sharks (or any kind) to get into Flathead Lake Montana?

Bull sharks are typically found in warm, coastal waters and can tolerate freshwater, but they generally inhabit areas like rivers and estuaries. Flathead Lake, Montana, is isolated and lacks a direct connection to the ocean, making it highly unlikely for bull sharks to enter. Additionally, the cold temperatures of Flathead Lake would not be suitable for their survival. Therefore, it is virtually impossible for bull sharks to inhabit Flathead Lake.
