As of April 2025, British Columbia (BC) is experiencing significant drought challenges, though conditions vary across the province. Approximately 19% of BC, or 183,139 square kilometers, is under drought conditions, while 42%, or 413,186 square kilometers, is classified as abnormally dry. This indicates that over 60% of the province is affected by some level of dryness or drought. Additionally, the average snowpack in April 2025 was reported to be 21% below normal, raising concerns about water availability in the coming months2.
Regional Variations and Improvements
In March 2025, much of BC saw above-average precipitation, leading to improvements in snowpack, streamflow, and moisture conditions in several areas3. Regions such as the Lower Mainland, southern Interior, and parts of the Thompson-Okanagan received significant rainfall, alleviating drought conditions in southern BC. This resulted in the removal of abnormally dry (D0) and moderate drought (D1) classifications in areas like Vancouver Island, the South Coast, and the southernmost border regions of Thompson-Okanagan3. Southeastern BC, from Lillooet to Kamloops, also saw reductions in moderate to severe drought levels3.
However, challenges persist in specific regions. Northern Vancouver Island, the central coast, western Cariboo, the Peace region, southern Thompson-Okanagan, and the east Kootenays received below-normal precipitation in March 20253. Long-term precipitation deficits continue to affect the Peace, Stikine, Cariboo, and Central Coast areas, with moderate (D1) to severe (D2) drought conditions lingering in northeastern BC and parts of the central interior, such as from Lillooet to Merritt3. The central coast and western Cariboo also reported significantly below-average snowpack, exacerbating water scarcity risks3.
Drought Classification and Impacts
BC uses a six-level drought classification system (0 to 5, with 5 being the most severe) based on water supply indicators like snow, rain, and river flows27. At the end of March 2025, 61% of the Pacific Region (encompassing BC) was classified as abnormally dry (D0) or in moderate to severe drought (D1 to D2), including 68% of the region's agricultural landscape3. Severe drought (D2) persists in areas like the Cariboo region and northeastern BC, driven by long-term moisture deficits and reduced snowfall3.
Drought in BC impacts various sectors, including agriculture, fisheries, and urban water supplies. Reduced water availability affects farmers, with irrigation demand projected to increase significantly by the 2050s due to hotter, drier summers5. Fish habitats, particularly for Pacific salmon, are threatened by low streamflows and higher water temperatures during drought periods7. Additionally, hydrological droughts-resulting from prolonged dry conditions-lead to reduced lake storage, decreased streamflow, and lowered groundwater levels, affecting both ecosystems and human use7.
Climate Change and Long-Term Trends
The current drought situation is compounded by broader climate trends. BC is experiencing rising average temperatures, warmer and drier summers, decreasing snowfall, earlier snowmelt, and receding glaciers, all of which reduce water availability during critical periods5. These changes increase the frequency and severity of drought, with extreme precipitation events contributing to runoff rather than replenishing soil moisture or reservoirs5.
Government and Community Response
The BC government is taking proactive measures to address drought risks, working with local governments and First Nations to improve water infrastructure, protect salmon habitats, and support community preparedness2. Programs like the Agriculture Water Infrastructure Program and water reimbursement initiatives aim to assist farmers and other water users2. BC Hydro is also adapting by conserving water at less impacted facilities, importing power during low water years, and enhancing weather forecasting and hydroclimate monitoring6.
Residents are encouraged to conserve water through small changes at home, such as using drought-resistant landscaping and water-efficient appliances, with many communities offering rebates for such initiatives2. During severe drought, the government may enforce reductions or halts in water use for licence holders to protect essential needs and the environment2.
In summary, while recent precipitation has brought some relief to southern BC, significant portions of the province remain under drought or abnormally dry conditions as of April 2025. Ongoing climate challenges and regional disparities in precipitation and snowpack underscore the need for continued conservation and adaptive management to mitigate the impacts of drought across BC.
