Colorado Division of Wildlife biologist Jon Ewert discusses electro-shocking
By Bob Berwyn
SUMMIT COUNTY — Heavy metals from abandoned mines and from natural sources have contaminated the Snake River in Summit County. As part of an ongoing effort to assess the impacts, the Colorado Division of Wildlife surveys a 600-foot reach of the river each year in early August.
