I know Lake Winnipeg - I believe the 3rd largest fresh water lake in North America (by area) - has a hydro control outlet and the lake can fluctuate by more than 1' in some years.Big Block Power wrote: Wed Apr 15, 2020 8:17 amReally rain caused it. I think the year before was snow they got a bunch. Did it really rain that much last year?cmattj wrote: Wed Apr 15, 2020 6:47 am
I found this in a Google search..
Apparently it is amount of rainfall.
What else can fill a lake?
I didn't look lately at Powell and meade. What fills those lakes? Now every time it gets real windy here they talk about flooding in Michigan and GreenBay. All the water gets pushed in one direction. Not the group either![]()
That's a great theory Br99 but there is no inlet or outlet control for lake Erie. About 92 percent of the water in Lake Erie comes from the upper lakes, through Lake St. Clair and the Detroit River, into Lake Erie. Lake Erie then flows into the Niagara River, into Lake Ontario.
The International Joint Commission can control outflow in the Great Lakes only from Superior and Ontario. But the impact is very small for Erie.
A famous book that many Lake Erie folks own is called Waters of Repose. It discusses the three main causes to Lake Erie level fluctuations.
1. Seasonal variations in rainfall
2. "Seiche" or bathtub effect (mainly in the Fall due to northeasterly winds)
3. Cyclical patterns
In the mid 1980's Lake Erie water levels were so high that most thought the sands of Long Point including the light house were doomed. By the early 1990's however water levels had fallen by almost 4 feet. We are currently in one of these "high" cyclical patterns. It's a record for sure but not unprecedented. Here is a water level history link for the Great Lakes from 1918-2020 if anyone is interested. It's put out by the US Army Corp of Engineers.
In the meantime, at least the risk of our duo-prop outdrive striking the bottom in Misery bay will be all but eliminated. At least that's my silver lining since it's a great area to wake board and tube.
