Spring Freshet

The warmer days and especially the warmer nights at higher elevations have finally got the snow melting in earnest.  The Bella Coola River has gone from spring 'green' to spring 'brown'.  Tributary streams have changed colour as well with the addition of some glacial melt in them like the river in this photo.

How many weeks the river stays high is really governed by the temperature.  A cool spring, means a long slow runoff, while hot May days will mean high water levels for a few days before it peaks and slows down closer to it's normal summer flow of late June and July.  Grizzly
