In Kitimat, both Radley and Hirsch Creek parks were under water. On November 1, the Kitimat River below Hirsch Creek recorded a maximum instantaneous discharge of 3,000 m 3 /s and a maximum daily discharge of 2,410 m 3 /s, setting extreme records (Environment Canada 1991). In the Kildala section, especially the Lillooet and Nass Streets, many basements were flooded with 4 ft. (1.2 m) of water. The main powerline to the Alcan smelter was threatened. On October 30, a mudslide coming down in the Prince George BC Rail yard 3 km north of Prince George killed two PGE employees who were repairing a clogged drainpipe. One man was buried alive and the second died of a heart attack while attempting to rescue the other. On November 2 at the Prince Rupert waterfront, a near flooding situation occurred because of a 22-ft. (6.6 m) high tide combined with heavy rain and wind. Hays Creek came nearly up to the road level. At the old dry-dock site, Cow bridge nearly flooded. Four major mudslides occurred on the Port Edward Arterial Highway. The railways were affected the most by the flooding. The rail line between Smithers-Terrace was closed. About 50 CNR workers in Smithers were temporarily laid off. Extensive damage occurred between Kitwanga-Kitselas. There were more than 25 washouts on a 53-mi. (84.8 km) stretch, with the worst damage at a point 103 mi. (164.8 km) west of Smithers. There were two major washouts at Mile 113.2. Washouts also occurred on the Kitimat Subdivision between Terrace-Kitimat. On October 31, the Bulkley subdivision between Smithers-Terrace was closed for 12 hours. A passenger train derailed after hitting a rockslide. There were no injuries and the passengers were transported by bus. On November 1, the high water, slides, and washouts started causing major problems on all three subdivisions linking Terrace. Part of a work train plunged into the Skeena River. On November 2, the remaining two parts of the train, the engine unit and caboose, went into the river. The train carried two crewmembers: an engine man and a conductor. The search for the bodies had to be abandoned, as the river was too high and moving too fast. Only a few days later when the river went down did divers recover the bodies of Frances William Watson and Kenneth Scott Bateman from the partially submerged locomotive. A new roadbed was put in and new track was laid at Mile 121, the site of the accident. Work crews, made up of about 100 men, worked around the clock to repair the washed-out sections between Terrace-Hazelton. From both directions crews worked towards the big washout at Mile 103.7, where rock fill had to be used. The washout 73 mi. (116.9 km) west of Smithers was repaired on November 3. The bridge span at Mile 113.8 was out of alignment, considerably slowing down the repairs. Freight and grain shipments were rerouted to Vancouver. Aqua Barges, operated by the Washington Tug and Barge Co. between Prince Rupert-Whittier, Alaska, were used on the Vancouver-Prince Rupert and Vancouver-Whittier runs until the line reopened. Canadian National used the Aqua Train between Vancouver-Prince Rupert with priorities on shipments of chemicals and fuel. Most of these were destined for Alcan in Kitimat and various lumber companies. CNR also used space on Eurocan and Cancel rail barges. The Prince Rupert to Terrace and Terrace to Kitimat subdivisions were both reopened on November 4. On the Bulkley Subdivision between Smithers-Terrace, which was hit worst, traffic resumed on December 3. However, the line was not fully restored for months. The opening of the line was just the first phase of rebuilding. Bank protection and reinforcing along with stream restraining was to follow. According to Alec Rennie of CNR’s Edmonton office, complete reconstruction would not be completed until August 1979. The gas pipeline of Pacific Northern Gas Ltd. (PNG) broke in the Telkwa Pass about 26 mi. (41.6 km) upriver from the Copper River bridge on Highway 16. According to John Low, PNG Sales and Service Manager in Terrace, over 6,000 ft. (1,800 m) of gas pipeline in five spots were actually floating in the river after floodwaters had changed the river’s course. Temporary repairs were made by replacing the 10-in. (25 cm) pipe with a 2-in. (5 cm) one. As the 2-in. connection was not adequate to provide full service, a switchover to 4 or 6-in. (10 or 15 cm) pipe was necessary. While efforts were underway to restore service, however, a second break, 12 mi. (19.2 km) east of the first one, was discovered and later repaired. A major section of the pipeline had to be repaired and moved away from the Copper River. Total damage to the PNG pipelines in the Copper River and Skeena River systems totaled approximately $6 million. It was the most expensive flood event in the company’s history (Bill Hough, pers. comm.). The BC Tel cable car used to access its facility up the Copper River was carried away. Telephone service and power were interrupted in Kitimat, Kitamaat Village, and Terrace. Roads along the Nass River washed out. In Greenville, a small tributary to the Nass River jumped its bank, causing damage to a gymnasium and cemetery. Rosswood and Cedarvale were without road access. At Rosswood, a torrent of water ripped across the highway, taking out a bridge and sweeping away a new home. The house was moved some 150 ft. (45 m) off its foundations. Greenville was isolated for more than a week. It took 10 days to make the final road repairs. On November 2, the Greenville water supply was hit by a mudslide, making the water muddy and reducing the pressure. The road at Kaseaden Camp, 12 mi. (19.2 km) north of Greenville was washed out. Helicopter relief flights to outlying communities were grounded by poor visibility. Because of the closure of Highway 16, the mail destined for Alaska was returned to Seattle. From there it was sent on the Alaska State Ferry. On November 1, the Kitsault River flooded Alice Arm to a depth of 1.5 m. As only four cabins were inhabited at the time, property damage was limited. A combination of scour and overtopping breached the low training wall in two places, 15 and 30 m in length, respectively. High water on November 2-3 washed out some of the Alice Arm wingdam. The cost of repair work was $46,075. The 1978 flooding report dated January 1979 completed by B. McMullen mentions the damage at Alice Arm. 132

Highway 37 between Kitwanga-Cranberry Junction was closed because of two large washouts between Cranberry Junction-Deltaic Creek and along the Stewart-Meziadin Highway 37A. Near Kitwanga, an access road serving two residences on Lot 3123 was flooded and washed out by the Kitwanga River. Erosion also caused loss of land downstream of this area on Lot 1320. The cost of a total of 450 m of bank protection was estimated at $38,500. The road leading to Stewart washed out, isolating the community. Apart from flooded basements, no major damage occurred in Stewart. The road to Stewart was still closed on November 8. Near Telkwa, minor flooding occurred in the lower Coal Mine Road area. The Telkwa River took out the abutment of a logging road some 20 mi. (32 km) along Coal Mine Road. At the confluence of the Telkwa and Bulkley rivers, high water aggravated erosion on the north bank of the Bulkley River opposite the confluence and also further downstream at Big Eddy Park. A preliminary cost estimate to provide dyking and broken rock riprap bank protection from the vicinity of the fire hall to Big Eddy Park was $195,000. Though some damage occurred in the Bella Coola area, the highway system sustained little damage. Some channel cleaning was carried out for the Ministry of Environment. The riprap protecting the Bella Coola airport eroded at two locations for a total distance of about 70 m. The estimated cost to reconstruct the riprap to a stable slope was $11,000. The Bella Coola Wilderness Airline float plane terminal on the south bank of the Bella Coola River sustained damage. The docks washed away and the docking area was infilled with river gravel. The estimated repair cost was $7,000. Near Firvale, 31 km east of Bella Coola, about 15 m off the end of the rock groyne eroded and a logjam partially blocked the relief channel. The cost of restorative work was estimated at $11,000 and improvement work at an additional $20,500. At Burnt Bridge Creek, about 37 km east of Bella Coola, a dike and bank protection (constructed after the 1968 flood to plug and overflow channel) eroded. As a result, water flowed down the channel and along the highway. The estimated cost of restoring the training dike to protect the highway and the farm was $6,000. An additional $6,000 was later required to restore the bank protection to the pre-flood condition. About 180 m of existing bank protection along Nooklikonnik Creek, 12 km east of Bella Coola, eroded at various locations upstream of the highway bridge. Additional gravel was sedimented in the stream channel. Restorative work of stream cleaning and bank protection repair was estimated at $19,000 and improvement work at an additional $39,000. Debris accumulation and channel accretion in the Salloompt River, 15 km east of Bella Coola, caused the river to change course along a 450-m reach through the Hayden and Meyer properties. The Meyer property suffered extensive flooding, with the water rising up to the main floor level at the house, about 1 m deep. The cost of cleaning the stream was estimated at $21,500. An alternative dyking proposal to provide more comprehensive flood protection was estimated to cost an additional $102,500. Along Thorsen Creek, 4 km east of Bella Coola, about 250 m of existing bank protection at various locations eroded and gravel deposition in the channel increased. The estimated cost of restoring the bank protection to a stable slope and removal of the newly deposited gravel was $28,000. An additional $55,000 was later required for gravel removal to improve a 1,040 m reach of the creek. On November 2, the Kispiox River near Hazelton recorded a maximum instantaneous discharge of 702 m 3 /s and a maximum daily discharge of 595 m 3 /s. Both of these are extremes for the period of record (Environment Canada 1991). On the Kispiox River, existing erosion conditions on the outside of river meanders increased noticeably, threatening cultivated fields, homesites, and a campsite. The cost of providing riprap at 11 sites, totaling 3,250 m in length, was estimated at $280,000. Logging roads in the Terrace area sustained heavy damage. Skeena Cellulose reported a cost of about $500,000 to repair the road system between the Clore-Kitnayakwa. It involved a major reconstruction of 10 km of the Copper River Forest road. In addition some $300,000 was spent on repair of the roads below the Clore. Repairs included a major washout at the Clore junction, road at Kelly Creek, and at Kilometre 15 and Kilometre 3. Cost claims for the reconstruction of the section 48.85-49.35 km near the Kitnayakwa junction totaled $125,328.49. An additional $1,266.06 was spent on the temporary repairs to the Kitnayakwa bridge. Eurocan reported to have spent a total of $33,171 on the repair of its roads in TFL 41. The repair included the removal of mudslides at 12.8 and 20 km on the Wedeene Main, at 2.4 km and 5.0 km on the W. 200, and small slides between 1.6-6.4 km on the W. 1300 Road. An additional $15,500 was planned for repair work on the Br. 200 W and Chist Main Line to be completed in 1979. Damage to roads and bridges on the Copper River Forest Road and Clore River Operational Road were estimated at $1,294,500 and $62,300, respectively. The latter was based on information supplied by CanCel. The storm also caused extensive environmental damage in the form of landslides, erosion, and washouts on the Queen Charlotte Islands. At Sachs Creek, both ends of the bridge were washed out and the bridge suffered a split piling. Hands (Haans) Creek had side wash along the wing wall. Gore Creek on 2 nd Avenue had its 42-in. (106 cm) diameter culvert washed out. Lawn Hill lost about 60 ft. (18 m) of shoulder. About one-third of the road width washed out. At Deep Creek, two 48-in. (1.2 m) diameter culverts were exposed for about 15 ft. (4.5 m). The roadway at the Skidegate Mission bridge was undermined. At Miller Creek, the roadway at the abutment washed out for 30 ft. (9 m) longitudinally. The stream changed course, requiring a wing wall and 600 ft. (180 m) of channelisation upstream. Sea erosion occurred on the Toe (Tow) Hill Road where the shoulder eroded 2 ft. (60 cm) wide for 200 ft. (60 m). Near Skidegate, some 1,000 ft. (300 m) of roadway required riprapping. Between October 29-November 1, the storm caused an estimated 1,000 slope failures all through the Queen Charlotte Islands (B.C. Ministry of Forests). In the Rennell Sound area, many new slope failures occurred. *3) The area received 284 mm of rain in three days. The weather station at Gospel Point recorded 277.6 mm of rain in three 133

In Kitimat, both Radley and Hirsch Creek parks were under water. On November 1, the Kitimat River below<br />

Hirsch Creek recorded a maximum instantaneous discharge <strong>of</strong> 3,000 m 3 /s and a maximum daily discharge <strong>of</strong> 2,410<br />

m 3 /s, setting extreme records (Environment Canada 1991). In the Kildala section, especially the Lillooet and Nass<br />

Streets, many basements were flooded with 4 ft. (1.2 m) <strong>of</strong> water. The main powerline to the Alcan smelter was<br />

threatened.<br />

On October 30, a mudslide coming down in the Prince George BC Rail yard 3 km north <strong>of</strong> Prince George killed<br />

two PGE employees who were repairing a clogged drainpipe. One man was buried alive and the second died <strong>of</strong> a heart attack<br />

while attempting to rescue the other.<br />

On November 2 at the Prince Rupert waterfront, a near flooding situation occurred because <strong>of</strong> a 22-ft. (6.6<br />

m) high tide combined with heavy rain and wind. Hays Creek came nearly up to the road level. At the old dry-dock<br />

site, Cow bridge nearly flooded. Four major mudslides occurred on the Port Edward Arterial Highway.<br />

The railways were affected the most by the flooding. The rail line between Smithers-Terrace was closed.<br />

About 50 CNR workers in Smithers were temporarily laid <strong>of</strong>f. Extensive damage occurred between Kitwanga-Kitselas.<br />

There were more than 25 washouts on a 53-mi. (84.8 km) stretch, with the worst damage at a point 103 mi. (164.8 km)<br />

west <strong>of</strong> Smithers. There were two major washouts at Mile 113.2. Washouts also occurred on the Kitimat Subdivision<br />

between Terrace-Kitimat. On October 31, the Bulkley subdivision between Smithers-Terrace was closed for 12 hours.<br />

A passenger train derailed after hitting a rockslide. There were no injuries and the passengers were transported by bus.<br />

On November 1, the high water, slides, and washouts started causing major problems on all three subdivisions linking<br />

Terrace. Part <strong>of</strong> a work train plunged into the Skeena River. On November 2, the remaining two parts <strong>of</strong> the train, the<br />

engine unit and caboose, went into the river. The train carried two crewmembers: an engine man and a conductor. The<br />
