Great Lakes Water LevelsJuly 26th, 2013 at 3:05 am by Bill Steffen under Bill's Blog, Weather
Check out the “Dragon Cloud” ready to eat “Big Red”, the lighthouse at Holland, Michigan. See the picture here full screen. (from Gary Brink at ReportIt). The most impressive figures in the weekly Great Lakes Water Level Report is the continued impressive rise in the water level of Lake Superior. Superior is a big lake and it takes 552 BILLION gallons of water to add one inch to the lake level. Lake Superior is up 6″ in the last month and is now 6″ higher than one year ago. The lake is now only 2″ below the average level. Lake Michigan/Huron is up 1″ in the last month and is 3″ higher than one year ago. It’s 19″ below the century average. Now, check out the levels downsteam from the (dredged) St. Clair River: Lake St. Clair, up 6″ in the last month, up 10″ in the last year and just one inch below average. Lake Erie, up 6″ in the last month, up 13″ in the last year and 4″ HIGHER than the long-term average level for July. Lake Ontario is now up a whopping 15″ in the last year and is now 5″ HIGHER than the century-average level for July. Despite the rise in Great Lakes water levels, we continue to see articles like this from just a few weeks ago, which says: “…comprehensive data collected and maintained by the (Army) Corps is reflecting continued low water conditions for at least four of the five Great Lakes over the course of 2013.” The data I have been posting each week is from the Army Corps of Engineers and freely available to anyone who knows where to look or bothers to make a call to the Army Corps or do a Google search. It’s frustrating to see misinformation spread around.
In other news: 1839 shipwreck found in Lake Ontario. The fight to keep Asian carp out of Lake Michigan continues. Tall ship hit by lightning (starts a fire) forcing it to cancel Great Lakes appearance.
