Upstream Flood Protection
The Springbank Off-Stream Reservoir, known as SR1, is a major regional project by the Government of Alberta, designed to reduce peak river levels during extreme events.
Located upstream of the Elbow River in Springbank, it temporarily diverts and stores excess water from the Elbow River, releasing it gradually once flows subside.
Local impact:
Reduced peak water levels through inner-city neighbourhoods along the Elbow River, including Elbow Park and Rideau Park
Decreased likelihood of overbank flooding
A system-wide approach to flood mitigation

Updated Floodplain Mapping
Floodplain mapping in areas such as Elbow Park and Rideau Park is evolving to reflect new infrastructure, including the completion of SR1, and updated modelling.
Development is guided by the most current adopted mapping, which continues to be refined as new systems and data are introduced.
