The turbulent flow caused by the logs and branches mixing deep and shallow water likely creates a higher oxygen content in this area, which would aid in gill oxygen uptake for the fish. This allows them to breathe easier and therefore increases their chances of survival, making it an attractive location for them to gather and feed.
