About Pot Island, Lake Winnisquam
Pot Island is a boat-access freshwater island dive on Lake Winnisquam, best for cool-water exploration and seasonal fish activity below the thermocline. The draw is the clear inland lake, island structure and summer trout-and-salmon movements rather than coral or open-water scenery. Boat wake and post-rain clarity changes are the main planning variables.
