Testing Lake Coeur d' Alene

Season 2 Episode 2 | 6m 38s | Video has closed captioning.

Tailings from more than a hundred years of mining have inhibited the growth of blue-green algae in Lake Coeur d’Alene. But as efforts to clean up the area’s watershed succeed, it also sets the stage for more blue-green algae growth. Scientific teams from the Coeur d’Alene Tribe and the State of Idaho use all the available tools to study the lake’s water quality.
