Abiotic factors in a hippo environment?

Yeah, I know, really weird question. I’m doing a powerpoint for my Aquaculture class and my animal I’m doing is a hippo. I need to know the abiotic factors of the water the hippo lives in (temperature, pH, alkalinity, dissolved oxygen, etc.). I literally can’t find anything for these things, and if any of you would just so happen to know these things, can you please tell me?
