On Saturday, September 1, 2012, thousands of dead fish and some seagulls were discovered on a 25 mile stretch of the north shores of Lake Erie.
Testing of lake water on Saturday did not reveal an apparent cause for the deaths, which would rule out a sewage spill, manure dump or other pollutive factor. Samples of the dead fish and birds were also sent to a lab for analysis.
Officials are speculating that a ‘lake inversion’, a rolling-over of the lake which brings colder waters containing less oxygen to the surface, may have occurred.
