Upper Animas River Basin Abandoned Mine Lands Initiative
Completed
By Colorado Water Science Center
October 20, 1996
The USGS Abandoned Mine Lands Initiative (AMLI) is developing and demonstrating scientific knowledge and technologies that will help Federal land management agencies clean up contamination in areas near abandoned hardrock mines across the Nation. The Initiative is being conducted in two pilot watersheds, the Upper Animas River Basin in Colorado and the Boulder River watershed in Montana, where the USGS is partnering with the U.S. Forest Service, BLM, NPS, EPA, and State agencies in Colorado and Montana.
OBJECTIVES:
- To define background (premining) conditions.
- To define baseline (current) conditions.
- To identify target sites that contribute most to environmental deterioration.
- To characterize target sites and processes for contaminant dispersal.
- To characterize ecosystem health and controlling processes.

Gold King Mine release (2015): USGS water-quality data and activities
On August 5, 2015, U.S. EPA was conducting an investigation of the Gold King Mine near Silverton, Colorado. While excavating as part of the investigation, water began leaking from the mine tunnel, and about three million gallons of water and sediment were released into Cement Creek, a tributary of the Animas River. The USGS provided pre- and post-release water-quality and streamflow data from...
USGS Abandoned Mine Lands Initiative
The U.S. Geological Survey (USGS) conducted an Abandoned Mine Lands (AML) Initiative during the fiscal years 1997 through 2001 to provide technical assistance in support of Federal Land Management Agency (FLMA) actions to remediate contamination associated with abandoned hard rock mining activities. This initiative was part of a larger strategy by the U.S. Department of the Interior and the U.S...
