> Many NOOMBYs consider local dams indispensable ties to their community’s past; in Billerica, some town officials have objected to the demolition of the Talbot Mills Dam on the grounds that “it has long served as a symbol of the Industrial Revolution” that remains “unquestionably one of the major focal points in the area.”
I used to hate the "but what about historical site upstream?" argument often used against dams. The prioritisation of a few tombs and piles of stone over what would improve the lives of thousands to tens of millions living now. It's kinda ironic seeing the same asinine argument being used from the other side...
That said, reducing dams to just hydroelectric generation is probably going to skew the narrative to the wrong direction.

Small dams, hydropwer and fish can co exist, though there is a loss in 'efficiency' in extracting the free power embodyed in flowing water.
Undershot wheels need to be relativly large and also leave room for fish to swim underneath them, but thats it, the wheel turns, the fish swim on by.
The real problem are 'mid sized' hydropower
turbines which cut of many large water sheds to fish migration, and I have been involved with water protectors in various ongoing attempts to remediate or remove varios dams and 'water control' aperatus, and the push back from entrenched intrests is rabid, anti everything but wealth and privlage, and the 'legal rights' to water sheds underpins many
an unearned fortune, and perfectly illustrate the very ancient concept of Hydraulic Despotism.
