Lake Superior question

[DeepDiverBob]

I am reading that the lake is reaching record lows. Is this bringing any wrecks into a more realistic range for diving?

Don't you have anything better to do at work than think up stuff like this?

dont you have anything better to do than acting like a diver on weekends?

It didn't seem all that low when we were up there. How low are they saying it is?

Lake Superior is now 6" below chart datum. The chart datum is set at the lowest normally expected level. The Local Notices to Mariners, http://www.navcen.uscg.gov/lnm/d9/lnm09322007.pdf, published weekly gives the current levels of all the Great Lakes. The levels are now at about there lowest levels, but they only vary by about four or five feet or so on their natural cycles.

6" doesn't seem like a lot when you compare it to the Oahe resovoir that is 44 feet low, but when you figure out how many billion gallons it takes to lower it that far you have to wonder.

I just read about lake Michgan losing water too

The levels of the Great Lakes are controlled by a combination of the precipitation in the watershed area and the evaporation rate. The efforts of man to influence this process are puny by comparison. We can and do make minor level changes in an effort to minimize costal erosion and maximize the fresh water we have available for industrial, domestic and agricultural use, but the scale of our efforts is dwarfed by the variables in nature.

Man only makes a big difference when it comes to destruction and pollution.

So Mother Nature isn't nearly as fragile as some would like us to believe. This was an interesting read - thanks!

Actually, history is clear that man pales in comparison to nature in the destruction category, too.
