Not all of New England’s water-powered mills sat along major rivers. This woolen mill in North Berwick, Maine, was founded by Quaker William Hill, beginning in 1862, and made blankets for Union soldiers. The Great Works River itself had been named by earlier Quakers.
The mill has been renovated into residences and offices.
My fondness for old mills, by the way, did prompt a novel, Big Inca.
