A July 2015 post shows young people jumping off the bridge in daylight, with comments such as "Awesome" and "Wow, looks like fun, be careful angel!!!"
But the NZ woman's death was the second water-related death in Sicamous this summer.
Police said initial investigation did not suggest any criminal activity was involved in the young woman's death.
The Coroners Service is now investigating the death. The news release states that no further information, including the woman's identity, will be released by either the RCMP or the Coroners Service.
