What is the minimum depth that wildlife park lakes must be for captive polar bears to dive as they would in the wild?

The minimum depth for wildlife park lakes to allow captive polar bears to dive as they would in the wild is generally recommended to be at least 10 to 12 feet. This depth enables bears to exhibit natural diving behaviors and provides sufficient space for swimming and foraging. Adequate depth is important for their physical and mental well-being, mimicking their natural habitat more closely.
