The first two documented, unassisted Flathead Lake length crossings were completed by Sarah Thomas and Craig Lenning on July 3, 2015. These swims were also ratified by MSF.

There have been several other claimed Flathead Lake swims. However, these are not officially documented and/or were assisted by wetsuits.
