A RADARSAT-2 satellite image located the Peace River ice front at km 747 (8 km upstream of Atlas Landing and 53 km downstream of Tompkins Landing) at 18:44 MST on November 26. The Peace River ice front advanced past the Vermilion Chutes last week, and arrived in Fort Vermilion in the early morning on Friday. The ice front has been advancing rapidly, between 20-30 km/day on average. In addition to the main ice front location, the November 26 RADARSAT satellite image also shows a possible bridging location slightly further upstream near km 730. If the river has closed up at that location, ice flowing on the Peace River will begin advancing the ice front from there, resulting in a small acceleration of freeze-up. Warm temperatures continue to be in the forecast for the next week, and ice production is expected to decrease, resulting in a slowing of the ice front advance.
Alberta Environment and Parks, and BC Hydro are in contact regarding river ice conditions and operation of the BC Hydro Peace River facilities.
Thanks to Ross Mercredi and John Zacharias from Mackenzie County, and Paul Catt from Alberta Transportation for their contributed river ice observations.
