In Canadian folklore, Ogopogo is a lake monster believed to inhabit Okanagan Lake in British Columbia, Canada. 
Some scholars have described the evolution of this entity based on First Nations folklore and widespread folk motifs of water monsters. Today, the Ogopogo plays a role in the commercial symbolism and media representation of the region.
Okanagan Lake is the largest of five interconnected freshwater lakes in the Okanagan Valley of British Columbia. It is named after the First Nations people who inhabited the region and was created when glacial melt flooded a valley 10,000 years ago. It stretches for 127.1 kilometers (79.0 miles) and has a maximum depth of 232.3 meters (762 feet) and an average depth of 75.9 meters (249 feet). The Okanagan has been frozen for eight winters in the past 110 years.Tourists see a strange silhouette in the river, which pales on closer inspection.
