A heavy snowfall of more than 5 ft. (1.5 m) earlier in December followed by thaw and three days of rain melted the ice and then it froze again. At least two families were evacuated. According to Barry Akehurst, regional director of the Provincial Emergency Program, the water was rising at a rate of 0.5 m an hour. The ice floe was about 3-4 mi. (4.8-6.4 km) long. The low-lying area around Penny was covered with ice “as far as the eye can see.” The river appeared to be solid for miles. On December 18, though the water level in the river went down about 5 in. (12.5 cm), was about 12-14 ft. (3.6-4.2 m) above normal. It was approaching the 1936 flood level, which was “the worst anyone could remember.” On December 19, the icejam was 6 km long and blocked the river both up and downstream of Penny. Fifteen cars parked on the south side of the river were flooded to their windshields and several boats were lost to river ice. More flooding was reported west of Penny near Aleza Lake. Icejams also cut a road near the community of Upper Fraser. Floodwaters washed away materials and tools at a bridge construction site behind the Northwood Pulp and Timber Ltd. behind its mill near Prince George. *1) Here, floodwaters went over the mark left by the spring freshet. The cofferdam for the bridge’s third pier was also damaged and was covered with muddy water. Worst damage done by the abnormal winter thaw occurred on December 16 on the Herrick River about 100 km east of Prince George. A tributary of the McGregor River went up 1.5 m, washing away parts of a bridge being built and dumping a crane into the water. ---------------------------- *1) The bridge is to be used to cut the hauling distance from the logging areas to the mill, bypassing routes that now take through city streets. About 16 km and almost an hour’s travelling will be saved (Times Colonist, December 19, 1980). December 23-27, 1980 Event type: Rain-on-snow flooding? Precipitation: Not available. Source: B.E. MacFayden. Rivers Subsection, Water Mgt. Branch. Southwest British Columbia. December 1980 Flooding Squamish to D’Arcy Area. Between December 25-27, southwestern British Columbia experienced mild temperatures and moderate to high rainfall on most areas below 5,000 ft. (1,500 m). This caused very rapid snowmelt and high runoff. Overtopping of river and creek banks caused extensive damage to property. The degree of damage prompted the Province of British Columbia to extend aid under the PEP program to those within an area described as follows, “A line extending east from the northern tip of Vancouver Island following the 51 st parallel to its junction with 120 degrees West longitude then south to the 49 th parallel then to Vancouver Island and including the Bella Coola Valley.” Just before south western British Columbia was hit by a severe storm, Bella Coola experienced what the federal government called a “separate event and not shareable.” The first $350,000 of the Bella Coola restoration was done under O.I.C. 2827 and the balance under O.I.C. 2861, which was later transferred by PEP to O.I.C. 2827. Total expenditure for Bella Coola: $726,208.77 (expenditure excluding above component of O.I.C. 2861: $376, 215.66;and $349,993.11. September 28, 1981 Event type: Fatal mudslide. Precipitation: Not applicable. Source: The Vancouver Sun, September 29, 1981. On September 28, a mudslide killed a 25-year old man working on the new BC Rail line near the Tumbler Ridge coal site. The victim was working across a creek and upslope from a cliff face that broke away. The slide rolled across the creek and continued about 30 m up the slope. The body was found under a metre of mud about 5 m from where he had been working. January 5-12, 1982 Event type: Snow (fatal) avalanches. Precipitation: Nass Camp (230.4 mm/4 days), January 5-8, 1982; Salvus Camp (174.0 mm/4 days), January 5-8, 1982; Tasu Sound (128.1 mm/2 days), January 6-7, 1982; Aiyansh (191.0 mm/3 days), January 6-8, 1982; Prince Rupert (152.6 mm/3 days), January 6-8, 1982; Ocean Falls (240.4 mm/3 days), January 6-8, 1982; Bella Coola (101.6 mm/1 day), January 7, 1982; Prince Rupert M. Circ (355.0 mm/7 days), January 6-12, 1982; Langara (76.0 mm/2 days), January 7-8, 1982; Smithers A (43.4 mm/2 days), January 7-8, 1982; Hartley Bay (243.2 mm/3 days), January 7-9, 1982; Terrace (98.8 mm/3 days), January 7-9, 1982.

Between January 5-10, the Kitimat-Terrace area recorded 140 cm of snow and winds gusting up to 100 km/h. On January 12, another 10 cm of snow brought the total snowfall in Terrace to more than 150 cm in less than a week. 140

Prince Rupert was without power for 12 hours as the power the transmission lines between Terrace-Prince Rupert went out. The Terrace airport was closed on January 7-8. In Terrace, the schools and banks were closed on January 8. The local storm caused more than $2 million damage. Hardest hit were B.C. Timber, BC Hydro, the Highway Department, and CNR. During the power interruption, B.C. Timber lost an estimated $120,000 a day in lost production. BC Hydro estimated the cost to run the emergency generators at a minimum of $350,000. The cost to repair the break in the main power line between Terrace-Prince Rupert was estimated at $100,000. According to Terrace District Highways Manager Bill Stanley, it would cost the Highways Department some $300,000 to repair the storm damage. Besides the life of one of its employees, the storm cost CNR about $150,000. The rail closure cost the grain elevators about $50,000. Two grain ships anchored in the harbour, at a cost of $5,000 each a day, had to wait for more grain to come in. Overnight January 10-11, Prince Rupert was hit by a power blackout. For more than a week the city was on emergency power generated by two back-up generators. The gas-powered twin generators, located near Port Edward, used 10 million ft. 3 (283,000 m 3 ) of gas a day, costing BC Hydro some $1,500 an hour. The B.C. Timber Watson Island pulpmill had its own source of electrical power, which was insufficient for full production. On January 10, a conductor on the 287-Kv powerline from Terrace was torn loose by the severe storm conditions on the Skeena River. Freezing rain on January 11 caused the line to break completely. A 2,900-ft. (870 m) span of line went down in an inaccessible ravine near Tyee. The site was only accessible by helicopter. Because of the weight of the ice, BC Hydro was forced to bring in a helicopter with a 4,500 lb. (2,025 kg) lift capacity from Chetwynd. The transmission line that carries the power to Prince Rupert from the Falls River generating station, which crosses the Skeena River above Tyee, went down in numerous places. Several of the transmission towers were damaged. The dangling wires became frozen in the drifting river ice and pulled some of the tower’s steel cross arms out of shape. Highway 16 between Prince Rupert-Terrace was closed for more than a week during the middle of January. Snowdrifts of 3-4 m hampered traffic on Highway 16 east and west of Terrace. The road was blocked by 24 snowslides, including two major avalanches at Mile 40.9 and 43.5. On January 14, several new slides came down in the Mile 40 area. Two convoys of trucks and private vehicles were the only non-emergency traffic to use the highway. During the highway closure, Trans Provincial Airlines operated a special once-a-day flight between Prince Rupert-Terrace using a DC-3 aircraft. Both Highway 16 and Highway 37 were reported open again on January 15. After a week closure Highway 16 opened on January 15.Vehicles continued to be escorted along sections where crews were still working removing the remains of the slides. Only two convoys of traffic escorted by highway crews were allowed to travel between Terrace-Prince Rupert. During he previous week, more than 150 cm of snow had fallen in the area. The rail line between Prince Rupert-Terrace was closed by snowslides. On January 7, a CNR Cat was buried. The operator escaped injury. A CNR snowplow derailed at slide path Rockface at 69.6 km (Mile 43.5). Fifty metres of track were damaged. On January 9, at slide path Long Slough at 81.6 km, a CNR worktrain was caught and partially buried. The VIA Rail passenger service was temporarily terminated at Smithers. On January 12 just before 4 p.m. 70 km west of Terrace, another slide came down at the same location as the January 7 avalanche. The slide occurred as provincial highway and railway workers were digging out equipment buried by the earlier slide. The slide that covered 60 m of track and Highway 16 buried and killed a 53-year old CNR section man. The victim was one of about 28 CNR employees working at the site of a derailed snowplow at Mile 43.5. Four vehicles and four other CNR employees were also caught in the 1-m deep slide. Highways crews reached three men caught in the slide within an hour. Two of the survivors were trapped in a railway caboose and a third was found outside in the snow. The fourth man was not uncovered until half an hour later. The victim had been buried in the snow under a truck for 38 minutes before he was found. During the coroner’s inquest Mike Zylicz, Ministry of Highways district avalanche technician said that during the day of the fatal slide the avalanche hazard had increased rapidly. Rising temperatures and rain added to the risk. Mark Ruelle, a Workers’ Compensation Board (WCB) industrial safety officer testified that he was in the area when the slide happened. While patrolling the highway with Zylicz, he ordered two independent contractors out of the avalanche area because of the deteriorating conditions. Ruelle explained that the WCB does have jurisdiction over independent employers working on CNR property but does not have control over the CNR itself. Zylicz said that he was getting along fine with the local CNR men in Terrace but added: “They are under continual pressure to keep the line open…” (The Vancouver Sun, February 25, 1982). *1) Between January 7-10, Smithers recorded 87.8 cm of snow. The bulk of this fell on January 7-8, with 42.8 and 27.6 cm, respectively. The snow followed a sharp rise in temperatures. (On January 5, Smithers had reported a temperature of -37 o C). Schools and some major businesses and employers shut down during the afternoons of January 7 and 8. The deep snow forced wildlife down from the mountains to the cleared roads in search of food. Logging operations in the area were temporarily shut down. Highway 37A between Meziadin-Stewart was closed due to a snowslide near Bear River. In a four-day period, 230 cm of fresh snow fell in the Nass Valley. Helicopter access was required until ground transportation links could be restored (Schaefer 1983). The Nass Valley Road was open to emergency traffic only, isolating the Nass Valley communities. Greenville was without power for five days. On January 10, repair crews reached the settlement from New Aiyansh by snow cat. 141
