River Ice Observation Report No. 5
January 5, 2017
Based on a RADARSAT-2 satellite image, the ice front was located at km 476 (80 km downstream of the Town of Peace River) at 18:37 MST on January 4. Since December 28, the ice front on the Peace River has advanced slowly, at approximately 2 km/day. Although temperatures have been warmer yesterday and today in the Peace region, cold weather last weekend and over the coming
weekend is anticipated to speed up the ice front’s rate of advance. Gauge records indicate that water levels at Sunny Valley have fallen approximately 1m from their peak on December 30th, although they remain high for this time of year. Water levels in Carcajou and Fort Vermilion are also high for this time of year, and have held steady for the past two weeks. The ice front is not expected to reach the Town of Peace River in the next week.
With the slowing of the ice front advance, the ice front on the Peace River is now approximately a week and a half behind 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.
