Three kayaking parties were on the Cuyahoga River: after portaging over Mat Road and re-entering the river, operator of vessel 1 began paddling toward another kayaker in the party that had fallen in the water and become separated from the vessel.  

Upon approaching the other kayaker, vessel 1 turned sideways and got caught on a partially submerged tree causing the operator to fall in the water as the vessel capsized.  Operator 1, who was not wearing a PFD, began floating down the river until able to grab onto a tree that also caught vessel 1 in a strainer.

The operator of vessel 1 was in the river for approximately 20 minutes prior to grabbing the tree.  The third kayaker in the party (operator 1's spouse), called 911 - at 20:19 Mantua Fire and Rescue responded and arrived at 20:29.
