I think dam is more dangerous for numerous life forms dependent on river water than the river itself. The drastic change in water flow cycle obviously will affect those fish, animals, birds and even people on the river banks.
I have also read that the dams cause harm to river itself by not allowing sand, mud etc. to flow further along with water and this slowly gets accumulated at the bottom and decreases depth of the river, I don't have in depth knowledge on this.
