Research for Lake Huron water levels Bayshore Broadcasting (10/26) The University of Toronto is undertaking a sweeping study of water levels in the Great Lakes, and Huron County is interested in taking part.
Temperatures throughout the Great Lakes basin were near average at the beginning of last weekend. However, they rose during the weekend, and the vast majority of the basin experienced temperatures that were more than 10 degrees above normal on Sunday. Temperatures continued to climb during the workweek, and the average temperature on Wednesday in many cities, such as Cleveland, OH and Duluth, MN, was more than 20 degrees above average. To date, Lakes Erie and Ontario have experienced significantly below average precipitation this month. This weekend, temperatures will start out around average on Friday, and will drop through Sunday. Cities such as Chicago, IL and Kalamazoo, MI are projected to experience high temperatures on Sunday not exceeding 30 degrees. On Monday, the basin will experience moderate temperatures. Considerable precipitation in the form of snow in the northern part of the basin, rain/snow mix in the central part, and rain in the southern part, is expected on Saturday. On Sunday, snow is expected in much of the basin.
Lake Level Conditions:
Lake Superior is 3 inches below its level of a year ago, while Lake Michigan-Huron is an inch above last yearís level. The level of Lakes St. Clair, Erie and Ontario are both 4 to 5 inches above what they were at this time last year. The water levels of Lakes Superior and Michigan-Huron are at the same level as they were a month ago, while Lakes St. Clair, Erie, and Ontario are 4,2, and 3 inches, respectively, lower than they were. Over the next 30 days, all lakes, with the exception of Lake St. Clair are expected to continue their seasonal decline. Lakes Superior and Michigan-Huron are predicted to fall 3 and 2 inches, respectively, while Lakes Erie and Ontario are both forecasted to decline 2 inches. Levels will remain above their long term average levels for this time of year, although Lake Ontario appears to be approaching its average level currently. See the Daily Levels page for more water level information.
Forecasted outflows / channel conditions:
Lake Superiorís outflow through the St. Maryís River is predicted to be above average for the month of October. Lake Michigan-Huronís outflow into the St. Clair River and Lake St. Clairís outflow into the Detroit River are forecasted to be above average in October. Likewise, the October outflow of Lake Erie into the Niagara River is projected to be above average, and Lake Ontarioís outflow into the St. Lawrence River is expected to be above average in October.
Official records are based on monthly average water levels and not daily water levels. Users of the Great Lakes, connecting channels and St. Lawrence River should keep informed of current conditions before undertaking any activities that could be affected by changing water levels. Mariners should utilize navigation charts and refer to current water level readings.
