Flood Risk Mapping for the Okanagan Valley Watershed
This report presents recent flood events (probabilities) and scenarios studies, including current and future lake management operations, wave effects, and a potential breach of flood control structures.
OBWB and partners had recently invested in critical data and detailed flood studies, including new LiDAR data and hydraulic modelling and mapping (NHC 2020).
This study leverages these investments in hazard modelling and improves our understanding of Okanagan flood risk.
