Geography
The influence of sea tides extends 18 km above the mouth to the town of Port Loney . This part of the river is also called the “sea It” as opposed to the “channel Onu” (Port Loney - Pont Trifan), which is part of the Nantes-Brest canal.
At the bend of the river near Landevenek, there is a station for decommissioned vessels awaiting dismantling or participating in training firing of the French Navy.
