Could lake naval warfare make a useful subject?

Is naval warfare on large lakes outside North America worth a video?

Yes. Riverine and lake warfare has a long, sometimes major history, but the Great Lakes are unusually well documented and their campaign-built infrastructure was often short-lived.

Many lake campaigns followed a temporary pattern: naval infrastructure appeared quickly for a particular struggle and disappeared soon afterward. Fleets, bases, and supporting facilities could matter greatly without leaving durable institutions. That makes inland naval warfare outside the Great Lakes harder to document, despite its long and sometimes large-scale history. The Great Lakes stand out because both their campaigns and infrastructure are unusually well recorded.
