Grab the slider and move it back and forth to compare before and after shots of the Grand River.

The Grand River rose dramatically on Saturday after the region received significant rainfall Thursday night into Friday morning. The rise and fall of the river was captured in a series of images taken from a Grand River Conservation Authority camera mounted near the West Montrose covered bridge.

The Authority also graphs river data, showing river flows at various spots on the Grand River with a significant jump on Saturday.

West Montrose reached a peak of 507.14 cubic metres per second last Friday night, according to the GRCA, a hundred times higher than the normal summer low flow, which is 5 cubic metres per second. In the historic 1974 flood, flows at West Montrose reached 670 m3/s.
