A high-water advisory has been issued for the Waterhen River in the Interlake, due to the possibility of frazil ice jams in the coming days and weeks.
Frazil ice, which has already begun to form due to colder weather, is a result of slush and ice crystals that do not totally freeze but have the potential to cause a jam and sudden river rises of a metre or more.
Water-level rises of up to one metre have been recorded at Waterhen in the last two days, according to the Manitoba Infrastructure and Transportation Hydrologic Forecast Centre. The river is lower than it was last year in mid-November by about 0.46 m, but still above normal for this time of the year.
Communities along the Waterhen River are advised to be vigilant as levels on the river could rise quickly.
