In freshwater systems this is done to enhance the amount of oxygen in the water. You can easily tell: calm waters are dark while turbulent waters appear whiter, right? This is due to the air dissolved & bubbling in the water. Why is it done? Well, oxygen is a great way to purify freshwater. Again, compare it to the opposite: stagnant water rapidly loses its oxygen (called hypoxia), after which it starts to 'rot' (not really, water itself doesn't rot, it's whatever is floating around in it i.e. algae / dead fish etc).
Another reason to have high levels of oxygen in fresh water is, of course, to keep the fish happy & healthy :-) Waterplants and plankton will in fact ADD to the oxygen in the water, but they need a fair amount as well, so again, if water is stagnant, it will lose its oxygen to the air above, which means loss of life underwater, further enhancing that downward spiral until the water is, as we call it, 'dead'.
So: let waters stream, froth & seeth freely :-)
