MONTROSE COUNTY, Colo. (KKCO/KJCT)-- A water facility near Bedrock, Colorado, has been known to trigger small earthquakes in the past, but wasn’t operating at the time of Monday morning’s quake.
In a press release, the U.S. Bureau of Reclamation, said employees at Paradox Valley Salinity Control Facility felt the earthquake, and their instruments measured it as a 4.1 magnitude. They have seismic monitoring equipment there because of the way the facility keeps brine from getting in the Dolores River. The concentrated salt water is injected into a well that’s 16,000 feet deep.
The well wasn’t operating at the time of the earthquake though, due to routine maintenance, according to the press release.
The USGS pinpoints the epicenter of the quake just south of Bedrock.
