Crews repair major water main break between Mammoth Hot Springs and Norris Junction

National Park Service crews worked through the night to locate and temporarily repair a major water line break that supplies water to all of the Mammoth Hot Springs facilities.  

The water main break was located under the road between the Mammoth Hot Springs Terraces and the YCC Camp Road (located about one mile south of the terraces). The break occurred on August 14. 


The park will plan a permanent fix on the line this fall once visitation and vehicle traffic subsides.
