The Industrial Arterial: 3491 - Fraser River (North Arm)

Navigate the busiest tug-and-barge corridor in the Lower Mainland with the professional authority of the Canadian Hydrographic Service (CHS). Chart 3491 is the definitive "road map" for mariners, providing the granular detail required for transiting the North Arm of the Fraser River, from its separation at New Westminster to its entry into the Strait of Georgia at Point Grey.

High-Precision Data for Urban Riverways

The North Arm is a unique maritime environment where industrial logistics, commercial fishing, and recreational rowing clubs converge. CHS Chart 3491 provides the "ground-truth" data required for safe pilotage:

• Exceptional 1:20,000 Scale: Offers the high-resolution data necessary for identifying safe leads through the technical dredging channels of Richmond and South Vancouver.

• Bridge & Infrastructure Awareness: Clearly identifies the clearance and positioning of the North Arm Bridge, Oak Street Bridge, and various rail crossings, essential for high-clearance industrial transit.

• Complex River Bathymetry: Provides accurate depth soundings and seafloor characteristics—crucial for mariners navigating the shifting sands near Iona Island and the North Arm Jetty.

• Hazard & Navigation Markers: Explicitly marks submerged hazards, river-specific buoys, and beacons updated through the latest Notices to Mariners (NOTMAR).
