There are a lot of problems with large scale dams.
They interfere with fish migration. For some species, this means disrupting their reproductive cycle.
They gradually accumulate sediment, so their reservoir slowly fills up and turns into land. This is one of the issues with the Aswan Dam, which is projected to have a much shorter lifespan than was initially projected due to high sediment accumulation.
The Aswan met all of its goals, but it's a disaster. The sediment rapidly accumulating behind the dam used to provide free fertilizer for farmers. Use of commercial fertilizer skyrocketed.
It's also the cause of a serious health crisis. Schistosomiasis cases have also skyrocketed.
The annual floods used to keep snail populations in check. The snails are the vector for this gruesome parasitic infection.
