Broad Water, or Broadwater (Welsh: Aber Dysynni) is a salt water lagoon near Tywyn, Wales formed from the silted up estuary of the River Dysynni. In the eighteenth and nineteenth centuries, the estuary was used by the shipbuilding industry, as small sailing ships were launched to carry peat from the local peat bogs. This industry was abandoned in the nineteenth century when the estuary became too silted up, forming the lagoon.
