Point on the Seine at the Poses-Amfreville dam, the tidal limit of the river upstream from Rouen. Anchoring is prohibited in the dam and lock zone.

Guide

Approach and anchoring

The Poses-Amfreville complex marks the head of the tidal Seine. Commercial lock operated by VNF on the right bank, pleasure boats share the chamber by VHF 18 request. Strong current below the dam on the ebb, wait for slack before approaching. Anchoring forbidden in the lock channel and weir zone.

Practical

No berths at the dam itself. Upstream of the lock the Seine is non-tidal and vessels continue towards Paris. Halte fluviale de Poses on the left bank 300 m SE, small pontoon with water and power for a limited number of boats.

History

The Poses-Amfreville dam, completed in 1885 and rebuilt in the 1970s, sets the boundary between the maritime Seine and the inland navigation Seine. It is the furthest point reached by the tide from Le Havre, 160 km inland.
