The Globe and Mail - Years of drought in Alberta and B.C. pushing freshwater supply into uncharted territory
“We must now prepare for water shortages of duration and magnitude not evident in hydrometric records or our collective awareness,”

This recent article from The Globe and Mail highlights the severe drought conditions in Alberta and British Columbia, pushing the region's freshwater supply into uncharted territory. With Western Canada now entering its third consecutive year of drought, the security of water resources is at critical risk, as the systems currently in place are struggling to adapt to the increasingly challenging climate conditions. The combination of low precipitation, reduced snowpack, and hotter temperatures is depleting the region’s natural water reserves faster than they can be replenished.
In communities like Merritt, B.C., residents face water restrictions, and local officials have warned that water pressure could be significantly reduced if conservation measures are not followed. The city relies on groundwater from natural aquifers, but these aquifers are no longer refilling at historic rates, placing the town’s long-term water security in jeopardy. The challenge is compounded by the fact that large-scale farming and irrigation systems, situated just outside city limits, continue to draw from the same dwindling water supplies without regulatory oversight.
Across Alberta and British Columbia, extreme drought is increasing the frequency of wildfires and further straining both surface water and groundwater reserves. In Alberta alone, more than 25 water shortage advisories were issued this year, while British Columbia has placed nearly 20% of its landmass under its most severe drought categories. Despite these conditions, many regions are still unprepared for the magnitude of water shortages they are likely to face in the coming decades, with water conservation measures implemented only as temporary solutions.
Scientists and public health officials are sounding the alarm, urging for more immediate and lasting measures to mitigate the impact of these growing threats. Ecologists have suggested that restoring natural systems could offer longer-term solutions. For example, the reintroduction of beavers to watershed areas is one approach being explored in British Columbia, as their dams can naturally regulate water flow and aid in groundwater replenishment. This innovative strategy offers hope for re-engineering more resilient ecosystems, but broader efforts are needed to address the root causes of water shortages.
The Canada1Water (C1W) project is proving instrumental in developing comprehensive solutions- by providing detailed modelling and extensive data on Canada’s water resources, C1W is helping policymakers, resource managers, and industries understand the impacts of climate change on freshwater availability. These insights are crucial for formulating effective water conservation strategies and ensuring the sustainability of critical sectors, such as agriculture and food production, which depend heavily on reliable water supplies. As Canada continues to confront the realities of climate change, projects like C1W are vital to ensuring the responsible management of its water resources and preparing for the challenges ahead.
