Where do fish go when river dries up?

Large, mobile fish such as trout or salmon may anticipate drought as water levels begin to dwindle, and leave for large lakes or seas.

How do droughts affect aquatic life?

With streams, drought causes loss of water volume, loss of habitat and disruption of connectivity, and if drying persists cease-to-flow can occur, usually breaking the stream up into a series of pools. With habitat loss or the stress of drying, some sub-dominant species may temporarily become dominant.
