Oh, you really should call them.
The problem is, NOAA and it's Center for Oceanographic Products and Services, and the Canadian Department of Fisheries and Oceans' Canadian Hydrographic Service, and the Army Corps of Engineers, and Environment Canada have all been measuring water levels on the Great Lakes since 1918 (before that actually, but it wasn't until 1918 that they had the full complement of gauges). These stations record a 3 minute average water level every 6 minutes, 24 hours a day 7 days a week. The data is archived in hourly, daily, and monthly averages, as well as annually.
The graphs and charts say you and the old man are wrong.
And I suppose that the foundation that I hunted in and the road never existed either? Corps of Engineers? Now THERE is a REAL organization, known for destroying river after river in this country, even known for putting channel markers in the Straights of Detroit that led to sand bars. Environment Canada? The bunch that allows unmarked oil well that rise within 3 feet of the surface of Lake Eire?
I believe too that you will find that some of the worst evaporation on the Lakes takes place in the winter, you know, lake effect snow. The ice cover protected the Lakes from a lot of that loss this year. It also protected the spawning reefs from the storms that often tear them up in winter.
The old man LIVED in that house, that is a FACT, there are pictures to PROVE it. The government can spout all the crap they want, that will NEVER change the facts. There was also a dance hall, where Lake Erie now sits. The spot where that hall was is about 200 yards off shore now.
The problem with government is that they are not able to wait till enough had got too old and died before coming out with their crap. They depend on the thought that NO one will question their "facts".
I defy ANYONE, government official or private citizen to dispute the fact of that road, that house and where the Lake should actually be right now, because they can't. The facts are irrefutable.
The Lakes are NOT low, not even for recent history, if anything they are a bit above the norm for this point in their cycle.
MOST of the damage done to Lake Erie was done prior to 1918. By that time most of the "Great Black Swamp" had already been drained and the majority of the 99% loss of marshes and wet prairie that once was the Lake, were gone. They will never be allowed to return, at least not as long as Man is here. Maybe, after Man is gone they will return, if the Lakes still exist.
