The term freshet is most commonly used to describe a spring thaw resulting from snow and ice melt in rivers located in the northern latitudes of North America, particularly Canada. A spring freshet can sometimes last several weeks on large river systems, resulting in significant inundation of flood plains as the snow pack melts in the river's catchment area.

A freshet can also refer to the following:

  • A flood resulting from heavy rain or a spring thaw.[1] Whereas heavy rain often causes a flash flood, a spring thaw event is generally a more incremental process, depending upon local climate and topography.
  • A stream, river or flood of fresh water which empties into the ocean, usually flowing through an estuary.[2]
  • A small stream of fresh water, irrespective of its outflow.[2][3]
  • A pool of fresh water, according to Samuel Johnson[4] and followed in Thomas Sheridan's dictionary, but this might have be an misinterpretation on Johnson's part, and it is at best not a common usage.[5][6]
