The rule here

This is a thermal feature to see, not a place to get in the water. The Black Rock Field Office, Winnemucca District puts it this way:

“The public is advised to avoid bathing or any type of contact with the spring water.”

Worth knowing: The BLM Black Rock Field Office issued this advisory in June 2020 after the spring water tested positive for E. Coli, Fecal Coliforms and Vibrio Cholera, noting that its warning signs had been vandalized or removed. The BLM has not published a rescission; confirm the current status with the field office before travelling.
