The goal of this project, completed over a 5-year timespan, was to improve the water quality of Kerber Creek by removing tailings containing high metals concentrations from the banks of the creek and placing them into on-site repositories or treating the tailings and surrounding soil with amendments. Twenty areas along the creek impacted by tailings were remediated (64 acres) and revegetated.

RMC reconstructed approximately 4.5 miles of Kerber Creek to stabilize channel boundaries by constructing 180 in-stream structures along the creek.

This project received two prestigious awards— the U.S. Forest Service Water Partner of the Year for the Rocky Mountain Region and the BLM 2010 Hardrock Mineral Environmental Award.
