May 17, 1974 was a sunny day, yet the Grand River breached its banks and caused massive flooding in downtown Cambridge. The river had a normal depth in May of about 0.61 m (or 2 feet) - during the flood its depth peaked at more than 5 metres, or 18 feet. Now 50 years later we want to show Cambridge both the past and the present of that Great Flood with an extraordinary event happening in May.
