They also influence daily weather by (1) moderating maximum and minimum temperatures, (2) increasing cloud cover and precipitation over and just downwind of the lakes during winter, and (3) decreasing summertime convective clouds and rainfall over the lakes. Pre-1918 data came from one water level gauge per lake. Researchers have developed a new integrated model to evaluate the economic impacts of climate change on the Canadian Great Lakes Basin. Data since 1918 have come from a designated set of gauges in each lake. Water levels of Lakes Michigan and Huron in the United States, 1918 to 2019. Climate 16:3535–3542. Higher temperatures suggest an increase in evaporation, which should then lead to an increase in precipitation. 2003. For example, the St. Clair river opening was enlarged in the 1910s, 1930s, and 1960s, contributing to greater outflows from Lakes Michigan and Huron.8 Similarly, natural year-to-year variability and other factors such as human use and wastewater discharges can influence water temperatures. Temporal effects of St. Clair River dredging on Lakes St. Clair and Erie water levels and connecting channel flow. Today, the Minister of International Development, the Honourable Karina Gould, on behalf of the Minister of Environment and Climate Change, the Honourable Jonathan Wilkinson, announced $5.1 million in funding to support 46 new projects to protect and restore the Great Lakes through the Great Lakes Protection Initiative in 2020–21. But environmental threats could change that. The Great Lakes Integrated Sciences + Assessments Center is a collaboration between the University of Michigan and Michigan State University. Lakes Michigan and Huron are shown together because they are connected at the same water level. But heavy human use over the past two centuries has taken its toll in the forms of habitat loss and fragmentation, influxes of invasive species, and polluted air, water, and sediments. - Videos from The Weather Channel | weather.com For each year, the shaded band shows the range of monthly average water levels, and the line in the middle shows the annual average. These lakes support a variety of ecosystems and play a vital role in the economy of the eight neighboring states and the Canadian province of Ontario, providing drinking water, shipping lanes, fisheries, recreational opportunities, and more.
