Le Plessis stream

Rising north of Caudan towards Saint-Séverin, the Le Plessis stream, also known locally as Kergoff stream, owes its name to the former seigniory of Le Plessis and its tidal mill located in Lanester not far from the port area of Le Rohu. Flowing upstream from the village through meadows and copses, then through a deep wooded valley, the stream flows into the industrial estate of Kerpont to the south and feeds the Goden marsh before flowing into the Blavet.
