The City of Calgary issued a water safety warning on Thursday to residents visiting local rivers and lakes as summer begins.

This alert follows a spike in emergency incidents that highlight the unpredictable nature of Alberta's waterways. The warning aims to prevent further accidents as more people head outdoors during the warmer months.

City officials released the reminder after firefighters rescued seven people [1] from local waterways within a single week. The surge in rescues indicates a growing risk for swimmers and boaters who may underestimate current speeds or water temperatures.

Local authorities said that rivers and lakes can present hidden dangers. These risks include strong undercurrents, and sudden depth changes that can overwhelm even experienced swimmers.

Firefighters are urging the public to remain vigilant and follow all posted safety signs. The city encourages residents to use designated swimming areas and avoid entering fast-moving water, especially during the spring runoff period.

While the city did not specify the exact locations of the rescues, the warning applies to all waterways within the Calgary area. Officials said that the recent string of emergencies serves as a critical reminder of the importance of water safety protocols.

Firefighters rescued seven people from local waterways within a single week.

The timing of this warning coincides with the seasonal increase in outdoor recreation, where a combination of melting snow and higher temperatures often leads to dangerous river conditions. By highlighting the seven recent rescues, the city is attempting to shift public perception from a sense of leisure to one of caution to reduce the strain on emergency services.
