The changes caused by declining ice cover on the Great Lakes are pretty bad, but it's not all doom and gloom. Ice cover on the Great Lakes has declined in the past 40 years with average ice coverage dropping up to 75 per cent, depending on the lake. "We rely a lot on the Great Lakes for shipping ... so an ice-free Great Lake is not a barrier to shipping. But beyond that there are a lot of negatives associated," said Mike McKay, the executive director for the Great Lakes Institute for Environmental Research (GLIER), based at the University of Windsor.
Glenn Harris, senior manager of environmental protection, said the region risks losing the social and economic benefits of Elk/Beaver Lake Regional Park without efforts to improve water quality. “Overall, water quality in the lakes is declining and with cyanobacterial [blue-green algae] blooms increasing in frequency and duration in Elk and Beaver Lakes, the risk to health of humans and pets and park use is rising,” said Harris.
