A full day of surface currents in the St. Lawrence from Québec past Île d'Orléans, Isle-aux-Coudres and the Saguenay mouth to Les Escoumins. The chart shows the tide wave running upriver: high water reaches Tadoussac first, Saint-Joseph-de-la-Rive about an hour and a half later and Québec almost four hours after Tadoussac.
