3656 - Useless Inlet & Fatty Basin Nautical Chart

The Hidden Coast: 3656 - Useless Inlet & Fatty Basin

Navigate the intricate and sheltered waters of the West Coast with the professional precision of the Canadian Hydrographic Service (CHS). Chart 3656 is the definitive "road map" for mariners and explorers entering Useless Inlet and the ecologically rich Fatty Basin, located within the renowned Barkley Sound region of Vancouver Island.

Precision Detail for Narrow Passages

The waters surrounding Fatty Basin are famous for their tidal complexity and narrow entrances that require exact timing and spatial awareness. CHS Chart 3656 is specifically designed to manage these challenges:

• Large-Scale Detail: Provides the granular data necessary to navigate the "reversing falls" and narrow tidal gates that lead into Fatty Basin.

• Hydrographic Depth Accuracy: Features precise depth soundings—essential for small craft and research vessels navigating the shallow sills and deep pockets of the inlet.

• Sea Bottom Characteristics: Identifies the nature of the bottom, providing critical information for anchoring in protected coves or identifying marine habitats.

• Coastal Elevations & Hazards: Clearly marks the dense island clusters, submerged rocks, and shoreline configurations characteristic of the Pacific Rim marine environment.

Essential for 2026 West Coast Exploration

As the development of ocean resources and interest in BC’s remote marine parks grow, the role of Chart 3656 is more vital than ever. Whether you are a commercial harvester, a marine scientist, or a recreational kayaker exploring the rugged beauty of Barkley Sound, this chart provides the "ground-truth" data required for safe and successful navigation.
