On March 25, 2026, the City of Wrenford released a spring flooding risk assessment for low-lying areas along the Tamsin River, Corvid Creek, and Ambrel Lake. As temperatures rise and snowpack melts, the City's engineering and emergency management teams have mapped zones that are most likely to see water overtopping banks or backing up into basements.
The assessment highlights Riverside Flats, the lower reaches of Corvid Creek Ravine, and parts of the Benchlands and Northgate neighbourhoods. Residents living near these waterways should expect higher water levels through April and May. Ice jams can form quickly as the river warms, causing sudden spikes in water height. The City is asking everyone in these areas to stay alert and follow local road closures if they appear.
Homeowners should take a few simple steps to protect their properties. Check that your sump pump is running and consider installing a backwater valve to stop sewage from backing up through your drains. If you need help getting ready, the City offers clear guidance on managing basement flooding and seepage. You can also grab a printable checklist for a household emergency kit that covers water, food, flashlights, and important documents.
"Knowing the risks helps you protect your home and family," said Liam O'Rourke, Community Emergency Management Coordinator. "We encourage everyone in the affected neighbourhoods to review the map and take simple steps before the thaw really picks up. A little preparation goes a long way when the water starts to rise."
Stay up to date on water levels and road conditions by registering for the City's alert system. The City also provides detailed flood risk maps that show which streets and lots are in the highest-risk zones. The assessment was prepared with hydrological data from the Tamsin Valley Conservation Authority.
