I know Frontier plans to have more animals diving but as a whole I think ever animal needs a depth requirement/limit. Mostly for realism purposes, as most animals (especially certain African species) often dislike or even naturally fear deep water and deep rivers (cause here there be crocodiles). Yes these are mostly bred in captivity animals but this is a natural instinct for them to avoid deeper waters. This would in my opinion go a long way for realism but not only that, it would greatly encourage the usage of water barriers, some zoos have this to keep larger animals dissuaded from attempting to climb walls and barriers, especially ones that don't actively seek to swim in the wild. One last reason why I think this would be really good is to help reduce drowning in habitat animals. 
I've lost pronghorn babies before because the water was to deep and they decided to just swim until they I guess became exhausted and actually drowned, so I've opted to avoid water whenever possible because of this. Especially in my habitats that don't need placed water.
