4145 - Mactaquac Lake (Saint John River) | 2-Sheet Nautical Set

Explore the expansive inland waters of New Brunswick with the CHS Chart 4145: Mactaquac Lake. This professional-grade navigational tool, produced by the Canadian Hydrographic Service (CHS), is a two-sheet nautical set covering the Saint John River valley upstream from the Mactaquac Dam.

Mactaquac Lake is a unique man-made reservoir created by the hydroelectric dam, stretching nearly 100 kilometres toward Woodstock. Because this area features submerged riverbanks, varying depths, and specific recreational zones, this 2-map set is an essential safety requirement for powerboaters, sailors, and anglers. The charts provide high-resolution hydrographic data at a 1:30,000 scale, ensuring clear visibility of the transformed river landscape.

Key Features include:

• Comprehensive 2-Sheet Set: Includes Sheets 4145A and 4145B, providing continuous coverage of the lake's winding corridor.
