Agency: NF Region District: R1 Ranger District: KINGS HILL Forest Service Tract: Watershed Code: 10030105 Forest or Resource Area: LEWIS AND CLARK Owner: P Impact: L Report: The location of the Silver Dyke Tailings is T 14N R 8E Sec. 15. The tailings are on private ground. There are no hazardous structures or openings at the site, and there are no discharging adits, springs, or seeps. It was estimated that 56,350 cubic yards of mill tailings remain at the site, but it is unknown what the volume of the tailings was previously. The tailings were uncontained, and the dam was washed away during a failure. There was no waste rock, but there was a tailings pile that consisted of small uniform rock fragments. Sediment samples showed that arsenic, barlum, cadmlum, copper, manganese, and lead were present. Water samples also showed copper, manganese, and lead. There were not any exceedances of the drinking water standards. |
