Summary of 2016 water quality monitoring results from the Animas River at Rotary Park
Mountain Studies Institute (MSI), a nonpartisan independent research center, has been monitoring water quality of the Animas River before, during, and after the Gold King Mine release. MSI continued to monitor the Animas River at Rotary Park in 2016 and 2017 and has water quality results from samples collected during spring runoff, base flows, and storm events.
In 2016, MSI distributed rack cards to help the public understand animas river water quality:
August 2016 - MSI RELEASES REPORT THAT EVALUATES THE IMPACTS TO ANIMAS RIVER BENTHIC MACROINVERTEBRATE POPULATIONS FROM THE AUGUST 2015 GOLD KING MINE RELEASE.
Mountain Studies Institute (MSI) surveyed benthic macroinvertebrate (BMI) populations along the Animas River from Silverton to Durango and analyzed potential impacts to these populations from the Gold King Mine release. MSI analyzed the immediate survival of benthic insects and also compared observations of BMI populations from the fall of 2014, prior to the Gold King Mine release, to the fall of 2015, two months after the release.
June 2016 - Spring Runoff Update
In early April, for the first time in eight months, the reach of the Animas River from Tall Timbers Resort (located in the Animas River canyon) to Durango rose to the same level it was when the Gold King Mine release occurred, due mostly to snowmelt. “We collected water quality samples to coincide with this flushing event in an effort to capture conditions when sediment deposited along the margins of the Animas River banks could have been re-suspended.”
The monitoring program is part of a partnership between MSI and the City of Durango to communicate Animas River water quality information to the public.
“Our monitoring program aims to understand whether water quality this spring is any different than previous years and if metal concentrations in the river pose any threat to human health, agriculture, or aquatic life” said Marcie Bidwell, MSI’s director. Read More -->
