I'm not going to read the entire thread.
>>2758326These are filled up by the tides, not from rivers, and I don't think it's a bad thing as long it's not on an industrial level.
>>2758669>the damns slow the water; allow plants to process the water and create habitatYes when the dams are big enough to flood nearby plains.
>percolate through the ground water which demonstrably benefits the aquifersA river is already connected to the aquifer, you don't need a little rock damn.
Damns block fish from moving up or down a river, dividing populations (=inbred), but beaver dams are made of wood, which are easily destroyed every few years by big floods. It isn't the case for rock dams.
Also, moving rocks in rivers causes harm to anything living under.
Basically, if you want to build dams, build them where the river is disconnect to the flood plain next to it, with wood and parallel to the flow of water.
>create habitatI can also add, flooded habitats produces more biomass, and keeps the water clean and fresh.

Keep doing the good work
