Whales don't live in fresh water because fresh water is too shallow and lacks the large quantities of prey they require to stay alive.
Some dolphins, which are small versions of whales, live in fresh water. Whales have been known to enter rivers, but, rivers do not have enough food to feed whales so they leave fairly soon.
