Our actions are now having a noticeable impact on temperatures and water flows, which accelerate drought. Receding water levels mean a fish will have less and less access to different types of habitat. Some fish are adapted to live in fast flowing water, others in slow moving pools. But during drought, they all must share the same shallow, sluggish water, an unfair competition that disfavour fish used to flowing water.
