4130 - Petitcodiac River and Cumberland Basin | Nautical Navigation Map

Navigate the upper reaches of the Bay of Fundy with the CHS Chart 4130: Petitcodiac River and Cumberland Basin. This essential nautical chart, produced by the Canadian Hydrographic Service (CHS), provides detailed coverage of the unique tidal waters where New Brunswick and Nova Scotia meet.

Rendered at a clear 1:50,000 scale, this chart is a critical resource for mariners navigating the extreme tidal environments of the Cumberland Basin and the Petitcodiac River. This region is world-renowned for its dramatic tidal bores and shifting mudflats, making accurate, up-to-date hydrographic data indispensable. The chart covers the strategic approaches to Amherst, Sackville, and River Hebert, as well as the coastal waters leading toward Moncton. It provides the precise bathymetry needed to identify safe channels, drying shoals, and underwater hazards in one of the most challenging navigational zones in North America.

Key Features include:

• Detailed Estuary Mapping: Covers the northernmost tips of Chignecto Bay, including the mouths of the Petitcodiac and Memramcook rivers.

• Hydrographic Precision: Features accurate depth soundings (at Chart Datum), seabed characteristics, and shoreline configurations.

• Navigational Aids: Clearly identifies buoys, beacons, and light stations essential for visual positioning amidst strong currents.

• Tidal Environment Data: Specifically designed to assist in navigating areas characterized by vast intertidal zones and significant water level fluctuations.

• Official Standards: An authoritative CHS publication that meets federal carriage requirements for commercial vessels and provides a vital safety standard for recreational boaters.
