Nature is disrupted. They aren't easily removed. Boats dump their exhaust oils into the lake where they wouldn't a river. They cost a lot to build. Sediment builds up in the bottom of them. Usually fish can't get upstream past them to spawn so there are less fish.

Advantages: 1. Controlled water supply 2. Hydro-electric power generation 3. Control of downstream flooding 4. New habitat Disadvantages: 1. Loss of existing use of land 2. May generate an earthquake swarm 3. Will generate a new micro-climate 4. Downstream effect may be unpredictable cf Aswan Dam and Colorado Dams All dams have a lifetime limit as they tend to silt up because they slow down the flow of water.

Aesthetics - dams make the natural environment disappear. Bullhead City AZ so named due to a beautiful rock formation - is lost underwater forever due to a dam. This area was special to the native americans as well - so socially and aesthetically it has impact - not to mention, dams are just plain ugly.
Socially, it can cut communities in two and also just change the way life is in the area - hunting, fishing, socializing.
Ethically - well lots of communities are downstream from dams and many lives lost due to poor dam construction - so ethically, morally, are they protecting people? Ethically, who wins by building the dam (what is the purpose?)
You didn't bring up ecologically, so I'll assume you've got that one already covered.

If you are seriously interested read a book titled "Cadillac Desert" by Marc Reisner. One of the factors not mentioned in the other answers is the tremendous evaporation of water from resevoirs. Granted, this is not lost water, just unusable and it is always transported somewhere else before it rains down again.
