On July 6, 2017, a two-hectare wildfire began west of 100 Mile House, British Columbia, Canada marking the beginning of the record-breaking 2017 wildfire season in British Columbia. [3] On July 7, 56 new fires started throughout British Columbia (BC) leading to several evacuation alerts, orders and the declaration of a provincial state of emergency by the Government of British Columbia. [4] By September 12, 158 fires were burning throughout the province. [5] A total of 12,161 square kilometres (1.2 million hectares) had burned by the end of the 2017 fire season, the largest total area burned in a fire season in recorded history (1.3% of BC total area). [6] This record was broken the following year, with five of BC's worst 10 fire seasons occurring since 2010. [6] However, the 2017 fire season was also notable for the largest number of total evacuees in a fire season (65,000 people), [7] as well as for the largest single fire ever in British Columbia. [8] Research indicates that human-caused climate change played a significant role in the fires. [7]
On July 7, the first of many major fires began, starting at two hectares and quickly progressing to be eight times larger by that evening, requiring an evacuation alert that same day. By July 7, 140 fires had started throughout BC, most of them in the central interior. The fires were aggressive and grew quickly, prompting a state of emergency as well as several evacuation alerts and orders. The next day, 182 total fires were active throughout the province prompted the issuing of up to 20 evacuation alerts and orders. The Emergency Operating Centre in Prince George was activated, and Emergency Social Services opened a reception centre and shelter at the College of New Caledonia.
Within three days, the first major fire, that started at two hectares, had grown to 4,000 hectares resulting in a mandatory evacuation order with up to 2,000 residents evacuated. By the following day over 10,000 Williams Lake residents were on an evacuation alert. On July 11, a total of 200 active fires and 4,000 evacuees registered in Prince George, led to addition lodging at the University of Northern British Columbia
2017's fire season caused the closure of Highway 97 from Kersley, south of Quesnel, all the way south to Pavilion (along Highway 99), and south of Ashcroft. It also closed Bella Coola Highway to westbound traffic and created evacuation alerts the entire length of the Bella Coola Highway from Precipice to the junction with Williams Lake. No other fire season had had this breadth of large fires across the province.
Three fires have achieved particularly notable sizes of over 100,000 hectares. First, the Hanceville Fire resulted from the merger of the Hanceville, Riske Creek and Raven Lake fires along Highway 20. As of August 20, the fire reached its largest size of 227,000 hectares, spreading as far south as Gang Ranch west of 100 Mile House. The Ashcroft Fire (also known as the Elephant Hill Fire) started on the Ashcroft Reserve, and spread north of Highway 99 to Green Lake, east of 100 Mile House. Finally the Nazko Complex started as a series of smaller fires west of Quesnel, two of which were notable in their own right, the Baezaeko River Fire, and the Tautri Lake Complex. These fires merged August 18, 2017, along with the Chezacut Fire and the Arc Mountain Fire, to form the Nazko Complex at over 432,000 hectares. This single fire was later renamed the Plateau Complex, centred on the Chilcotin Plateau. Overall this behemoth fire covered a combined area of 545,151 hectares, making it the largest fire in B.C.'s recorded history (roughly the same size as Prince Edward Island). This fire was the result of nearly 20 separate fires merging.
On July 7, a provincial state of emergency was declared by Todd Stone, Minister of Transportation and Infrastructure, on behalf of the Government of British Columbia. [4] The state of emergency was extended on July 19 and again on August 4, and again on August 18, and again on September 1. [9] This was the first state of emergency for British Columbia in 14 years, and the longest state of emergency in the province's history. [10] On September 15, the state of emergency finally ended at midnight.
A combination of dry lightning and human-caused fires started the 2017 BC wildfires. Human-caused climate change also played a significant role. [7] Human-caused fires were both accidental and intentional; all wildfires in BC are investigated to determine the fire origin and cause. [11] Fire bans and restrictions were put in place to limit further human-caused fires. [12]
A study by researchers at Environment and Climate Change Canada found that climate change played a major role in the fires. They concluded that “the risk factors affecting the event, and the area burned itself, were made substantially greater by anthropogenic climate change... and that anthropogenic climate change increased the area burned by a factor of 7–11.” [7]
Heat waves and a lack of rainfall throughout the province leading up to the wildfires had dried out vegetation and soil. Also, pine forests with many pine trees killed by mountain pine beetle provided optimal fuel for fires. Considering these contributing factors, most areas of BC were rated as at extreme or high risk of fire. [13] The wildfires grew in size so quickly because of strong winds, in some regions up to 70 km/h. [14]
On July 4, a car crash on Highway 1 near Cherry Creek caused a 15-hectare fire that was later contained by a crew of 47 fire fighters, 11 planes and a helicopter. [15]
More than 39,000 people were evacuated from their homes and 30,000 cattle were threatened. [16] The wildfires reportedly destroyed over 300 buildings ranging from homes and barns to commercial structures. [17]
On July 15, a fire helicopter under contract to the BC Wildfire Service crashed in the Chilcotin. The only crew on board was a pilot who suffered non-life-threatening injuries. [18]
As of August 13, 3,906 firefighters were deployed to fight the fires, including 647 out-of-province personnel and 1,606 contractors. Crews fought the fires with the assistance of 233 helicopters and airplanes. [5] In addition, 50 Australian firefighters, [16] 80 Fire and Emergency New Zealand firefighters and 108 fire personnel from Mexico [17] came to BC's aid.
Over 15 reception centres opened province-wide. In addition, five cities, from Surrey to Williams Lake opened group lodging centres for evacuees. [19] The Red Cross opened support centres in Kamloops and Williams Lake and provided assistance to those affected by the fires with funds from donors, the federal government and the province of BC, as promised by Premier Christy Clark. [20]
On September 5, 2017, Canadian Minister of Agriculture Lawrence MacAulay announced that farmers and ranchers impacted by the wildfires would be provided $20 million in aid by various levels of government. [21]
Williams Lake is a city in the Central Interior of British Columbia, in the central part of a region known as the Cariboo. Williams Lake is one of the largest cites, by population of metropolitan area, in the Cariboo after neighbouring Quesnel. The city is famous for the Williams Lake Stampede, which was once the second largest professional rodeo in Canada, after only the Calgary Stampede.
The Chilcotin River /tʃɪlˈkoʊtɪn/ located in Southern British Columbia, Canada is a 241 km (150 mi) long tributary of the Fraser River. The name Chilcotin comes from Tŝilhqot’in, meaning "ochre river people," where ochre refers to the mineral used by Tŝilhqot’in Nation and other Indigenous communities as a base for paint or dye. The Chilcotin River, Chilko River and Lake, and Taseko River and Lake make up the Chilcotin River watershed. This 19,200 km2 (7,400 sq mi) watershed drains the Chilcotin Plateau which reaches north to south from the Nechako Plateau to Bridge River county and east to west from Fraser River to the Coast Mountains. It is also one of twelve watersheds that make up the Fraser River Basin. Made up of seven major tributaries, Chilcotin River starts northeast of Itcha Mountain, flowing southeast until it joins the Fraser River south of Williams Lake, 22 km (14 mi) upstream from Gang Ranch.
Eastgate is a small cabin community located at the Eastern portal of Manning Provincial Park in the Cascade Mountains of British Columbia, Canada. It is located in the Similkameen-Okanagan Forest District. The community store and gas station, and formerly the now closed restaurant, are popular for visitors of Manning Park Resort and ski area. The settlement is located along the uppermost Similkameen River. Access to Eastgate is limited solely to east–west travel along the Hope-Princeton Highway. The community has one gas station, a Canco gas station, a cabin rental and a bed and breakfast. The gas station was formerly host to the Eastgate Canada Post Office. The Eastgate Volunteer Fire Department, with three trucks, provides fire protection for the area and frequently participates in forest fire control in the region. The small town shows up on some government maps as Manning Park.
2015 Canadian wildfires were a series of wildfires across Canada and Alaska in July 2015 which spread smoke across most of North America. Over two hundred fires were ablaze across British Columbia, Saskatchewan, and Alberta.
On May 1, 2016, a wildfire began southwest of Fort McMurray, Alberta, Canada. On May 3, it swept through the community, forcing the largest wildfire evacuation in Alberta's history, with upwards of 88,000 people forced from their homes. Firefighters were assisted by personnel from both the Canadian Armed Forces and Royal Canadian Mounted Police, as well as other Canadian provincial agencies, to fight the wildfire. Aid for evacuees was provided by various governments and via donations through the Canadian Red Cross and other local and national charitable organizations.
The 2017 Washington wildfires were a series of wildfires that burned over the course of 2017, a year that set weather records for heat and aridity in both Western Washington and Eastern Washington.
By the end of June 2018, there had been more than 560 wildfires in British Columbia.
The 2019 Alberta wildfires have been described by NASA as part of an extreme fire season in the province. In 2019 there were a total of 803,393.32 hectares, which is over 3.5 times more land area burned than in the five-year average burned. The five year average is 747 fires destroying 146,360.08 hectares. There were 644 wildfires recorded in Alberta. By May 31, 10,000 people had been evacuated, 16 homes, and the Steen River CN railway bridge, had been destroyed.
Binta Lake Fire was a lightning-caused wildfire in Southeast of Burns Lake, British Columbia that started on Wednesday, July 28, 2010, and lasted for more than a month. It was the largest fire in the province in 2010. The fire burned a total area of 400 square kilometers. The fire caused thick smoke in surrounding areas, evacuation orders in the region, and damaged merchantable timber.
The 2021 British Columbia wildfires burned across the Canadian province of British Columbia. The severity of the 2021 wildfire season has been attributed to the combination of extreme heat, lower than normal rainfall, and "repeated severe thunderstorms and lightning events" by the BC Wildfire Service, and possibly exacerbated by human-caused climate change.
A wildfire began on June 30, 2021 just south of the village of Lytton in the interior of British Columbia, Canada. The fire destroyed much of Lytton and caused two civilian fatalities, announced July 3. Several missing residents, still unaccounted for at that time, were later located. The fire, one of the 2021 British Columbia wildfires throughout the province, was facilitated by the 2021 Western North America heat wave.
The White Rock Lake fire was a wildfire in Thompson-Nicola Regional District, British Columbia. It began July 13, 2021 as one of the 2021 B.C. wildfires and resulted in the destruction of Monte Lake. It totalled 83,047 hectares and was classified as out of control. Insured losses total an estimated $77 million Canadian Dollars, according to one agency, which in late September expected the number of claims to top 800, most of them related to residential property.
The 2021 Pacific Northwest floods were a series of floods that affected British Columbia, Canada, and parts of neighboring Washington state in the United States. The flooding and numerous mass wasting events were caused by a Pineapple Express, a type of atmospheric river, which brought heavy rain to parts of southern British Columbia and northwestern United States. The natural disaster prompted a state of emergency for the province of British Columbia.
The 2023 Washington wildfire season officially began in March 2023 in the US state of Washington.
Beginning in March 2023, and with increased intensity starting in June, Canada was affected by a record-setting series of wildfires. All 13 provinces and territories were affected, with large fires in Alberta, British Columbia, the Northwest Territories, Nova Scotia, Ontario, and Quebec. The 2023 wildfire season had the most area burned in Canada's recorded history, surpassing the 1989, 1995, and 2014 fire seasons, as well as in recorded North American history, surpassing the 2020 Western US wildfire season.
The McDougall Creek Fire was a wildfire in the Okanagan region of British Columbia, Canada as part of the 2023 Canadian wildfires. It started near West Kelowna on August 15, 2023, and was discovered at 5:59 pm PDT. The wildfire forced the evacuation of West Kelowna and parts of Kelowna.
The Bush Creek East fire was a wildfire in the Canadian province of British Columbia. The fire caused a major loss of structures and forced the evacuation of thousands of residents.
