OUR GEM: New research will examine zinc’s role in Coeur d’Alene Lake

Understanding Coeur d’Alene Lake’s health means looking beyond nutrient and metal concentrations in the water to see how they interact with each other and the ecosystem. A newly funded University of Idaho research project will examine that distinction for zinc, helping lake managers better understand its effects on algae and what those effects could mean as mining cleanup continues.

The project is led by University of Idaho researchers Jeff Langman and Eric Aston. It is part of a new slate of research supported by the Idaho Water Resources Research Institute (IWRRI) to address water-quality, drought, snow-monitoring and flood-risk challenges across Idaho.
