Spring's first signs


Recommended Posts

I think we are in for a bi-polar warm-cold March the way the jet stream has had such deep troughs.....which probably means lots of wind also.  The lake is pretty warm.  It has not quite reached complete isothermy as there are still some islands of 41 degree water offshore.  Those are where the kings are wintering.  Having three banks of 40 degree water evenly spaced out in the different basins, I am predicting the whole South shore is going to enjoy spring kings.

A satellite photo of the Lake Erie ice coverage showed only fifty per cent ice coverage yesterday. Warm water will be flowing from the Welland Canal, Port Dahlousie and Niagara River sooner than expected. Get ready .

Our intake temp at work went from 34 degrees a couple weeks ago to 39 degrees. 

An up welling of bottom lake water. The physical property of water is it becomes denser or heavier around thirty nine degrees F. That is why ice rises to the surface as it becomes colder and fish do not freeze under the ice. An offshore wind blows the cold surface water away and the bottom water rises to the surface. In summer conditions the colder bottom water rises to the surface during off shore wind events. Ice fishing in Lake Ontario bays is dangerous as the warmer bottom water can rise up and melt the ice from below also.
