What's New Georgian Bay regains some water Midland Mirror (3/11) In Georgian Bayís, the water levels are higher than last summer and this is linked in part to the ice cover, but concerns about the future are still unabated.
Unprecedented seasonal water level dynamics (3/10) Research recently published in the Bulletin of the American Meteorological Society by NOAA Great Lakes Environmental Research Laboratory scientists shows dramatic and unexpected changes in the seasonal water-level cycle of Lake Erie and in the Great Lakes regional water budget.
Levels of Lake Michigan, Lake Huron may rise 8 to 14 inches Milwaukee Journal Sentinel (3/6) This winter's heavy snow and massive ice cover will drive up the water levels of Lake Michigan and Lake Huron by 8 to 14 inches over the next six months, compared with the same time last year, the U.S. Army Corps of Engineers said.
Sick of winter? There is a silver lining! WSBT-TV - South Bend, IN (3/3) Experts say that by next fall, water temperatures will be cooler and evaporation rates will be lower than usual due to this winter's cold weather. Therefore, Great Lakes water levels should rise a bit.
A couple of clipper systems passed through Great Lakes basin the past week leaving behind a dusting of snow. Below seasonal average temperatures carried by an arctic air mass have led to increased ice coverage on the Great Lakes. Temperatures throughout the Great Lakes basin are predicted to trend below their seasonal average through early next week. Night time lows are likely to fall well below zero across the upper Great Lakes. The presence of this polar system will bring a chance of measureable snow to start the weekend. Another chance of snow is likely at the start of the new week.
Water Level Conditions:
Lakes Superior and Michigan-Huron are 12 and 15 inches, respectively, above their levels of a year ago. Lakes St. Clair, Erie, and Ontario are 8, 5, and 10 inches, respectively, above what they were at this time last year. Over the next 30 days, Lake Superior is expected to drop 2 inches and Lake Michigan-Huron is expected to remain near its current level. Lakes St Clair and Erie are expected to rise 3 inches and 1 inch respectively over the next 30 days while Lake Ontario is expected to drop 1 inch. Ice building in the connecting channels can cause significant water level fluctuations, especially in Lake St. Clair.
See the Great Lakes Water Levels web page for more water level information.
Forecasted outflows / channel conditions:
Lake Superiorís outflow through the St. Maryís River is predicted to be near average for the month of January. Lake Michigan-Huronís outflow into the St. Clair River and the Lake St. Clair outflow into the Detroit River are also expected to be near average. Likewise, the outflow of Lake Erie into the Niagara River and the outflow of Lake Ontario into the St. Lawrence River are projected to be near average in January.
Official records are based on monthly average water levels and not daily water levels. Lake Michigan-Huron is below chart datum and expected to remain below datum over the next several months. 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. Ice information can be found at the National Ice Centerís website.
