This occurred during a school kayaking trip during which the victim capsized her vessel and became pinned on a rock in fast moving waters.  It appears that she was unable to remove herself from the kayak due to the speed of the water and subsequently drowned.  Swift water rescue teams responded and recovered her body from the point she had gotten pinned by the water.  Information regarding the type of kayak that was used was not collected on scene and as such was not included in the report.
