Mark Sobchuck of the Ministry of Natural Resources says they want to find out what impact global warming is having on fish populations.
"We're interested in the impacts of a changing climate on how the thermocline in the various lakes sets up," says Sobchuck, "how its established, the depth its established and the length of times its maintained during the year."
Monitoring devices have been placed in 22 lakes across the region.
