River Ice Observation Report No. 4

December 28, 2016

Based on a RADARSAT-2 satellite image, the ice front was located at km 492 (1 km downstream of Sunny Valley) at 7:12 MST on December 28. This is 96 km downstream of the highway bridge in the Town of Peace River. Warm temperatures have stalled the Peace River ice front downstream of Sunny Valley for the past week. Ice production resumed with the cold temperatures late last week and over the weekend, but the ice front is expected to slow once more with the above season temperatures this week. Water levels have risen in Sunny Valley as the ice front approaches. Gauge records indicate that water levels in Sunny Valley now are similar to what they were last year during freeze-up. The ice front is expected to advance past Sunny Valley today. Temperatures are forecast to fall slowly to seasonal levels next week. This is expected to increase the rate of ice advance early in the new year. The ice front is not expected to reach the Town of Peace River in the next week.

The ice front on the Peace River is now approximately at its average location for this time of year.
Alberta Environment and Parks, and BC Hydro are in contact regarding river ice conditions and operation of the BC Hydro Peace River facilities.
