The Mystery of Lake Tasikallak

A major 2002 fish kill that still raises research questions

In 2002, Lake Tasikallak (Qc, Canada) experienced a major fish kill of unknown origin. With support from FROST funding, scientist Isabelle Laurion and her collaborators are revisiting this mystery by installing moorings to collect seasonal data on temperature, oxygen, and light penetration. These measurements will feed models to predict how climatic variations may impact lake chemistry, fish survival, and the livelihoods of communities that depend on these ecosystems.
