This seems like something that I should have known, and may have heard in school, but it never stuck.

Watermills aren't just for "milling flour".

Duh!

In the last week or two I've been reading about old industry in the UK, and kept reading about "cotton mills," and forges that were located on a river next to cotton mills, and then finally, it clicked when I saw a video about a saw mill that was located on a river.

The only watermill that I'd ever known about was a flour mill.

But it only makes sense that ANY function that is repetitive and can be mechanized and powered can be powered by a mill that's powered by a water wheel.

A forge can use the wheel to pump the bellows and hammer the steel and whatever other repetitive functions are needed.

A saw mill can process entire trees from timber to lumber.

Etc - like I said, major "you're a dumbarse, masraum" moment for me.
