Flood
Floods are Canada’s most common natural hazard. They can happen any time of year, usually due to heavy rain, rapid snowmelt, ice jams, or—less often—the failure of a natural or human-made dam. Our region has many rivers, lakes, and streams, including three major floodplains, each has a history of significant flooding.:
- Nanaimo River Floodplain
- Little Qualicum River Floodplain
- Englishman River Floodplain
Staying Safe Outdoors
During flood season:
- Check local media for flood advisories before hiking or traveling.
- Watch for changing conditions.
- Tell someone your destination and return time.
- Keep children and pets away from fast-flowing water.
- Carry an emergency supply kit.
If a Flood Occurs
Know what to do, where to get information, and what to take—or leave behind—before you evacuate.
Disaster Recovery Webinar Recording
This RDN Disaster Recovery Webinar (recorded in 2021) includes Disaster Financial Assistance (DFA), which is a provincial government program designed to assist homeowners, tenants, small business owners and farm owners with funds to cover uninsurable, essential losses to their properties.

Returning Home After a Flood
Returning to your home after a flood can be overwhelming. The RDN has prepared resources to help you take it one step at a time while prioritizing your health and safety.
Before re-entering your home, please refer to these resources:
Flood Advisories, Watches, Warnings
Similar to general Evacuation Stages, there is a series of warnings to the public regarding floods issued by the River Forecast Centre.
High Streamflow Advisory
River levels are rising or expected to rise rapidly, but that no major flooding is expected. Minor flooding in low-lying areas is possible.
Watch
Government or agency awareness of a possible threat and monitoring of the situation increases. River levels are rising and will approach or may exceed bankfull. Flooding of areas adjacent to affected rivers may occur.
Warning
Public information when a threat is imminent and immediate measures to minimize or prevent damage to property and infrastructure are initiated. River levels have exceeded bankfull or will exceed bankfull imminently, and that flooding of areas adjacent to the rivers affected will result.
Harm Prevention measures may include:
- A Flood Evacuation Alert for residents to be prepared to evacuate, or
- A Flood Evacuation Order is a mandatory order for residents to evacuate under the authority of a State of Emergency
- Declaration. For more specific information on evacuation stages and powers of local authorities in emergencies or disasters, please read the article Evacuation Information and Procedures.
RDN Flood Risk Assessment
In 2019, the RDN completed a Flood Risk Assessment as part of the National Disaster Mitigation Program to inform the next steps to disaster risk reduction activities while increasing the capacity and resiliency of the region as a whole.
River and Coastal Flood Maps
River and Coastal Flood Maps have recently been developed to better understand the present and future flood hazards to inform land use, emergency planning, and infrastructure management.
Sandbags
During the wet fall and winter months, residents in flood-prone areas should prepare early and keep any sandbags in place until spring if already deployed. Sandbagging is a do-it-yourself task. Ensure you have enough sand, sandbags, shovels, and time to prepare properly. For guidance on flooding and sandbag use. Learn more about being Flood Ready (Government of Canada).
If you need help filling or placing sandbags, reach out to neighbors, family, or friends.
How to Build a Sandbag Dike
You can prevent or reduce flood damage to your home by building a sandbag dike. It takes two people about one hour to fill and place 100 sandbags, giving you a 1-x-20-foot wall.
| Height above dike | Bags required |
|---|---|
| 1/3 metre | 600 |
| 2/3 metre | 2,000 |
| 1 metre | 3,400 |
- Locate the sandbag dike on high ground as close as possible to your home.
- Dig a bonding trench, one sack deep by two sacks wide.
- Alternate the direction of sacks (e.g. bottom layer lengthwise with dike, next layer crosswise).
- Sacks should be approximately half-filled with clay, silt or sand.
- Tying or sewing of sacks is not necessary.
- Lap unfilled portion under next sack.
- Press firmly in place.
Below is a video that shows how to properly fill and place sandbags:
