When the Anaconda Company stopped pumping groundwater out of the West Camp in 1965, the water level in the Travona quickly climbed to over 5,500 feet. Water started seeping into basements in the area bounded by Iron Street in the north, Front Street in the south, Montana Street in the west, and Maryland Street in the east. Surface water seeps were also observed north of Centennial Avenue between Montana Street and Missoula Gulch. In response, what became known as “Relief Well No. 21” was installed close to the spot where today’s new main pump is located. Keeping the Travona water more than 70 feet lower than it was back in 1965 should ensure that this case of ‘high water history’ won’t repeat itself.
