Based on a RADARSAT-2 satellite image, the ice front was located at km 916 (84 km downstream of Fort Vermilion) at 7:05 MST on November 19. The ice front is currently located on the downstream end of the Vermilion Chutes. In order for the ice front to advance beyond these rapids, the ice in the river must either bridge and form a new cover above the chutes, or it must build up ice over several weeks in order to ‘climb up’ this steep section of river. Temperatures over the past few weeks have been quite frosty, with below seasonal temperatures driving lots of ice production on the river. Thanks to Ross Mercredi and John Zacharias from Mackenzie County, and Paul Catt from Alberta Transportation for their river ice observations and photos so far! A new RADARSAT satellite image will be available early next week.
In the next week, temperatures across the province are going up. Fort Vermilion won’t see too much of a boost, but the Town of Peace River will warm to above seasonal, and temperatures in the headwaters of the Peace River will climb to above zero. There’s lots of ice in the system now, but with this warming trend, we expect ice production to decrease.
Alberta Environment and Parks, and BC Hydro are in contact regarding river ice conditions and operation of the BC Hydro Peace River facilities.
