Climate Change Impacts on Great Lakes Water Levels

Climate Change Impacts on Great Lakes Water Levels

Great Lakes water levels fluctuate in response to such environmental factors as lake precipitation, runoff, and evaporation, as well as human influences like water withdrawals and controls of water flow between lakes. In light of future climate change scenarios, the water level changes we could face will have impacts on not only our Great Lakes ecosystems, but the public health of our coastal communities. To help better understand the implications of climate change on the future of Great Lakes water levels, this webinar will address the following questions:

  • What processes govern the water levels of the Great Lakes? What information is used to understand these processes, and what are the different sources of uncertainty in this information?
  • How is uncertainty in existing and future climate conditions expressed in water level forecasts?
  • How might we incorporate uncertainty of future water levels into our water resource and infrastructure management decisions?
