Yes, platypuses do live near rivers, creeks and clean water sources. They can only find their food in freshwater, and they also dig their burrows in the banks of creeks and rivers.
They modify Rivers and Lakes because they need to make it clean and not dirty so they can drink, wash their hands, or bodies in that water.
We can control pollution being dumped into the rivers, regularly remove trash, and quickly address toxic spills to keep them clean. Rivers will naturally repair themselves but this process can take many generations or longer depending on the severity of the problems.
WE should keep our river clean to conserve the aquatic life and prevent human beings from suffering from the water borne diseases.
