Flooding
Floods are common in B.C. and can happen any time of year.
Severe floods
The most severe floods are usually due to heavy rain and melting snow. Floods disrupt our lives and can be dangerous. They can damage roads, making it hard to travel or transport things. They can wipe out fish habitat and watersheds – nature’s flood defense system. Floods can also damage sacred and cultural sites, making them hard to access.
Future risks of flooding in B.C.
As B.C.’s climate continues to warm, increasingly severe and frequent floods will put more and more communities and people at risk.
Spring weather is getting unpredictable, which can lead to earlier and faster snowpack melting. Throughout the year, we’re having more storms and extreme rainfall events. These changes in the flow of water can overwhelm rivers, streams and soil, leading to flooding and landslides.
Health impacts
People face serious safety and health hazards before, during and after flooding. This can impact our physical and mental well-being.
The effects of floods and extreme weather events don’t often end with the flood itself. People can carry the trauma and health impacts of these events with them for years. Floods can carry bacteria and chemicals into our drinking water. They can also cause mold and fungus that is bad for our respiratory and immune systems.
Road and highway damage
Floods can damage roads and highways. This makes it difficult to get around and transport supplies. It also means emergency vehicles can’t get where they are going.
Water contamination
The amount and force of flood water can damage habitats of marine and animal life. Floods can disrupt salmon migration paths, hurt the fish and wash away their eggs. Floods can wash toxic chemicals into groundwater and streams. This pollution can travel up the food chain and affect species like bears, wolves and orcas.
BC is taking action
Guided by input from people across B.C., we are working with local, federal and Indigenous governments to prepare for the impacts of flooding. Explore how we are helping strengthen ecosystems and communities.
Highway Infrastructure Climate Adaptation Program
Making highways safer by making them more resilient and prepared for changing climate conditions like flooding or extreme weather.
B.C. Flood Strategy and Resilience Plan
Collaborating with local, federal and Indigenous governments to prepare for and respond to the growing risk of flood. Released in 2023 and will launch in 2025.
Community Emergency Preparedness Fund
Increasing funding to help communities and support regional collaboration in responding to emergencies.
