Ice and snow bring more water to Great Lakes

Finally there is some good news about water levels in the Great Lakes.  It also lends a sense of purpose to the frigid temperatures we have endured this winter.  All I hope for now is that boaters winterized their boats properly and there is no increase in  freezing damage claims. 

The Ottawa Citizen article is linked below but here are the highlights:

  • Lakes Huron and Michigan, which are joined and share the same water level, are 33 centimetres below the long-term average. But that’s a huge improvement: This time last year they were 70 cm below average.   
  •  Lake Superior and Lake Erie are only two and four cm below average, respectively. Ontario is actually above average by four cm.
  •   Ice covers 88.4 per cent of the total surface of all the lakes, up 10 percentage points in the past week. It’s threatening to bust through the 1979 record of 94 per cent if the freeze continues into March.
 Ice is the key to the rising levels, Nevin said. “Evaporation is the largest source of water loss.”
