Advantages of dams:
Positives:

-provides irrigation
-provides water supply

Negatives:
-ecosystems can be destroyed
-expensive
-produce much less energy
-break in massive flash flood
-corrosion may occur
-fish may be damaged which causes population to decrease
-changes in channel morphology
-debris jammed in tributaries
-increased sediment storage
For the time it takes to fill the dam, there'd be no flow of water downstream. Might be awkward for someone in that direction who'd been relying on that water.
Depending on size, the area upstreams of the wall will be flooded. Kinda awkward for someone using that area of land.
A dam will prevent any fish from travelling up & down the river.
