Navigate one of the most unique and ecologically significant stretches of the St. Lawrence with the 1312 - Lac Saint-Pierre Nautical Chart. This professional-grade hydrographic reference is the definitive guide for the expansive waters of Lac Saint-Pierre, covering the vital shipping corridor from the islands of Sorel to the open reaches leading toward Trois-Rivières. Whether you are pilotage a deep-draft commercial vessel through the dredged channel or a recreational boater exploring the winding bayous of the archipelago, Chart 1312 provides the "ground-truth" data required for safe passage.
Produced to the rigorous standards of the Canadian Hydrographic Service (CHS), Chart 1312 offers comprehensive information for this technical waterway:
Main Shipping Channel Coverage: Features high-resolution depth soundings and bathymetry for the St. Lawrence Seaway channel, including current patterns and maintained depths through the lake's center.
The Sorel Archipelago: Detailed mapping of the western entrance, including the complex network of islands (Île de Grâce, Île aux Ours) and the secondary channels used by local fishers and pleasure craft.
Navigational Hazards & Signaling: Clearly marks the range lights, lighthouses (such as ÃŽle du Moine), and buoys essential for maintaining position within the narrow dredged channels.
UNESCO Biosphere Context: Provides the topographical and hydrographic context for this protected world heritage site, marking shoals, marshlands, and protected shallow-water zones.
Beyond its functional use on a bridge, this chart serves as a sophisticated piece of maritime history and art for those inspired by the Bas-Saint-Laurent.
Technical Elegance: Showcases the intricate line work, sounding density, and maritime symbols that define professional Canadian hydrography.
Vivid Print Quality: Printed with high-definition clarity to ensure every light characteristic, depth contour, and buoy is sharp and legible for study or display.
The Perfect Regional Memento: An ideal gift for sailors, residents of Nicolet or Sainte-Anne-de-Sorel, and anyone with a deep connection to the "sea within the river."
