Ice Report No. 15
February 5, 2018
The responsibility for ice observations on the Peace River passes to BC Hydro from Alberta Environment and Parks (AEP) when the ice front is upstream of Dunvegan. That responsibility was transferred on January 29, 2018. The numbering of reports is a continuation of the AEP reports. You may notice a variation in the format of the report as a result.
Ground observations were conducted on Saturday, Feb 3, 2018. The air temperature at the time was around -23 oC but had been at around -30 oC earlier that morning. An intact ice cover was found at km 270 and the ice floes were moving very slowly with 100% surface ice concentration at km 262. Based on these two observations it was estimated that the ice front was around km 264 on Feb 3, 2015 13:30 MST and was still advancing upstream. This placed it 100 km downstream of the Clayhurst Bridge near the BC-AB Border, 32 km upstream of Dunvegan and 133 km upstream from the Town of Peace River. Since its last furthest advance observed on Feb 1, the ice front had advanced 32 km in 2.5 days. The average rate of advance was 12.7 km/day.
The ice front is expected to continue its upstream advance this week with the cold weather. A warming in the forecast for this weekend could cause secondary consolidations, possibly downstream as far as Dunvegan and could produce elevated river levels.
