Lake Superior levels below average but up from last year

Sunday, November 03, 2013   by: SooToday.com Staff

NEWS RELEASE

INTERNATIONAL
LAKE SUPERIOR
BOARD OF CONTROL

***************************
Update on Lake Superior outflow

The International Lake Superior Board of Control, under authority granted to it by the International Joint Commission, has set the Lake Superior outflow to 2,260 cubic meters per second (m 3/s) (79.8 thousand cubic feet per second (tcfs)) for the month of November, effective November 4, 2013.

The outflow is as prescribed by Plan 1977-A and is 510 m 3/s (18.0 tcfs) less than the October outflow.

The November outflow will be released by discharging approximately 2,162 m 3/s (76.4 tcfs) through the three hydropower plants and passing most of the remaining flow through the control structure at the head of the St. Marys Rapids.

The gate setting of the control structure for the month of November will be decreased to the equivalent of one-half gate open (four gates open 20 centimetres (cm) each), effective November 4.

As a result, the flow and water levels in the St. Marys Rapids are expected to decrease.

Anglers need to remain cautious and be aware of changing flows and water levels, and the return to lower flows and levels in the rapids during November.

There will be no change to the setting of Gate #1 which supplies water to the channel north of the Fishery Remedial Dike.

This past month, the water supplies to Lake Superior and Lakes Michigan-Huron were above average.

Currently, the Lake Superior level is about 7 centimetres (cm) (3 inches) below its long-term average beginning-of-November level, and 28 cm (11 inches) above the level recorded a year ago.

It is 22 cm (9 inches) above its chart datum level.

This past month the level of Lake Superior declined 4 cm (2 inches), slightly more than the average decline of 3 cm (1 inch) in October.

The level of Lake Superior is expected to continue its seasonal decline in November.

The level of Lakes Michigan-Huron also declined 4 cm (2 inches) this past month, which is less than the average decline of 7 cm (3 inches) for October.

The level of Lakes Michigan-Huron is 41 cm (16 inches) below its long-term average beginning-of-November level, and is 28 cm (11 inches) higher than it was a year ago.

Lakes Michigan-Huron is now 2 cm (1 inch) below its chart datum level.

The level of Lakes Michigan-Huron is expected to continue its seasonal decline through November.

The Board continues to monitor conditions both on Lake Superior and downstream, and will advise the International Joint Commission accordingly on those conditions.

BG Margaret Burcham is the United States Board member.

Mr. Jaymie Gadal is the Board member for Canada.

Floods everywhere and our lake is still dropping. Must be magical.

Ya, or people stealing the water, bottling it & selling it back to us!
Sam C 11/4/2013 7:20:44 AM Report

Read that again... the level is slightly below average but IS up.

As well, don't blame bottling companies for the decline. If they didn't bottle it and sell it back to you -- as water, juice, pop, beer, etc -- you would be drinking the same amount from the tap.

Managing the flow is a balancing act, trying to maintain levels in ALL the Great Lakes, in order to preserve shipping capacity, recreation, etc.

Don't tell us who not to blame, it's Nestle water...don't buy it .....and who gives them permission to take it in the first place....USA! Then sell it to Canadians! They are right, flooding everywhere, but Superior is still below average! Enough is enough, when will Canadians learn to rise together to stop this. They are selling our natural resources and it needs to stop.

Bugalugs....you are correct that it is primarily USA factors over the past half dozen decades that has caused a almost irreverseable situation, but the bottled water is peanuts compared to 1) the St Clair Dredging and 2 ) the Chicago divirsion (to join Lake Michigan to Missisipi river many decades ago)
Think of Lake Michigan and Huron as essentially one individual Lake and so when many decades ago the USA decided it would be great to run barges from Lake Michigan to Mississipi they cut a canal so that water would start to outflow out of Michigan into Mississipi river, that is the same canal they are trying now to prevent those carp species from Mississipi from entering Great Lakes. NO one made a big deal about this diversion back then thninke lakes are so big it won't matter... and the USA contiues to blame great Lakes levels on global warming etc. But then to add insult to injury at the south end of Huron where it goes thru to St Clair they dredged it down an extra 20 feet for shippping so picture an extra 20 by 100 ft hole letting water escape 24 hours a day 365 days a year. There is some talk of putting in slow down berms, but that talk has been going for 10 years and Obama is going to keep avoiding it.
So as much as we would like to hold back Superior as the last decent level lake, the rest of the commercial needs of Great Lake will continue to be drained to support our southern "friends".

Sam C, are you from the Sault? Being here 40 years, I can tell you the Lake is DOWN 3 or 4 feet or more. Don't be flapping your gums unless you know what you are talking about.

On the bright side people with lake front property get more and more free frontal land every year.
Your 1 Acre waterfront lot can turn into 2 acres on its own over time .
