The rule here
This is a thermal feature to see, not a place to get in the water. Grand Teton National Park puts it this way:
“Entering the warm spring is not recommended.”

Worth knowing: The park says the pool contains high levels of E. coli and the presence of Naegleria fowleri, and that released aquarium fish have disrupted the ecosystem.
