Ogopogo Searches and Evidence — Okanagan Lake, British Columbia (2000s)

Since the early 2000s, organized searches for Ogopogo in Okanagan Lake have employed increasingly sophisticated technology. In 2000, a team of researchers deployed underwater cameras and sonar equipment near Rattlesnake Island, one of the most frequently cited locations for Ogopogo sightings. While no definitive evidence was captured, sonar readings detected large objects at depth that could not be identified as known lake fauna. In 2005, a documentary film crew using a remotely operated vehicle (ROV) explored the deep waters near Squally Point, descending to over five hundred feet. The ROV footage revealed an unexpectedly diverse underwater ecosystem, including large Kokanee salmon and lake trout, but no anomalous creatures. Numerous photographs and video clips have been submitted over the years, mostly showing dark, elongated shapes on the water's surface. A 2011 cell phone video shot from the shore near Kelowna appeared to show two dark humps moving in tandem across the lake's surface, generating significant local media coverage. Researchers have proposed various explanations for Ogopogo sightings, including large sturgeon (which can grow to over twelve feet in Pacific Northwest lakes), floating logs, wave patterns created by boat wakes in the narrow lake, and otters swimming in a line. The lake's extreme depth and length make comprehensive surveying extremely difficult.
