Anchor Ice Exposed at Low Flow


Exposed Anchor Ice on the Kananaskis River, AB (Canada), Nov. 26, 2012

Anchor ice occurs frequently on the Kananaskis River – it forms when suspended frazil ice adheres to the stream bed.  Because the river is regulated for hydro-power production, water levels vary substantially over the day, each day.  This leaves anchor ice exposed at low flow.
