Lake Major is one of the largest undisturbed lakes in the Halifax Regional Municipality, stretching approximately 8 kilometers in length and serving as a primary drinking water supply for the Dartmouth area. The lake is wide through most of its midsection, narrowing toward both the head and tail ends, giving it a distinctive elongated shape that creates a variety of fishing environments along its length. The surrounding watershed remains largely undeveloped and natural, with the only notable built structures being a pumping station roughly 1 kilometer upstream from the southern access area and a small cluster of homes near the lake's lower end. This relatively pristine setting makes Lake Major a unique fishery within close proximity to a major urban center.
