Lake Superior water levels still a foot below normal
Published Saturday, January 26, 2008 8:52:33 AM Central Time
Lake Superior water levels in late December remained about a foot below normal, according to the National Weather Service office in Marquette.
Despite some heavy rainfall during September and October in the Lake Superior drainage basin, water levels were a foot below normal, but seven to eight inches above the record-low level set in 1925.
Above normal temperatures and lack of precipitation for 2005, 2006 and 2007 caused the lake's water level to come within an inch or two of record lows in 2007, but the situation has been gradually improving.
The highest December water level was 603.1 feet in 1986, while the low was 600.1 in 1925. On Dec. 1, 2007, it was 600.9, and it fell to 600.7 on Dec. 31.
Water levels in the Lake Michigan/Huron drainage basins also fell slowly in December, according to the NWS. They hovered nearly 15 inches below the long-term mean and just one to two inches above the record low established in 1964

The lowering water levels in Lake Huron have many residents concerned and a petition has been put together to encourage the Canadian Government to take action.
Mitch Twolan is on the Bruce County Agriculture, Tourism and Planning, Land Division Committee.
He feels that county council needs to become involved in the issue, because it can affect tourism along the lakeshore.
A report has indicated that Lake Huron water levels have dropped by 60 centimeters since 1970.

Another Reason for Lower Lake Huron Water Level
We know that water levels in the Great Lakes are cyclical and that we've been at the low end of the cycle for the last few years.
But a coastal resources manager with the Lake Huron Centre for Coastal Conservation says even within those cycles there can be some very dramatic fluctuations in water levels.
Geoff Peach says this natural phenomenon is called sloshing or a seiche and it can be caused by either very high winds or a dramatic drop in barometric pressure before a storm.
Peach says the water action is similar to sloshing water back and forth in a bathtub and the drop in levels is so dramatic that a person on a shallow beach can suddenly have twenty to thirty feet of beach that they didn't have previously.
Peach says just like water in a bathtub, when the wind stops, or the barametric pressure returns to normal, the water levels move back and forth and then settle at their previous levels.
The Lake Huron Centre for Coastal Conservation spokesperson says that usually happens within a few hours.

The evaporation factor Warm winter weather + frozen ground = lower lake levels

Lake Huron is in a fog, part of a gloomy cycle that's pushing water levels to record lows, scientists say.
Last week, a winter storm dropped more than a foot of snow over the Great Lakes. Over the weekend, warmer temperatures melted that snow, and much of that water evaporated into the air.
The cycle has been playing out for the past 30 years in the Great Lakes, said Cynthia Sellinger, co-author of a paper to be published Tuesday in Environmental Science & Technology, a scientific journal.
