Today's Weather Trivia

22 July

2005: In the Nine Mile River in East Hants, NS, up to 1,000 silver-coloured shad died. Some floated on the surface, others rotted on shore. Environmental conditions-low-water levels, lack of oxygen, and very high water temperatures-may have suffocated the fish. Several Nova Scotia communities experienced their driest summer on record, some receiving only 32% of normal rainfall.
