Lagoon Introduction
The only single-mouth lagoon landscape in Taiwan is found at Dapeng Bay, with a water area of approximately 3,500 meters, a width of about 1,800 meters, and a lagoon area exceeding 532 hectares, with a depth of about 2 to 6 meters. The formation of the lagoon topography is due to the sediment carried by Donggang River and Linbian River from upstream into the sea, which, through the action of tidal winds, creates a long, narrow sandy area outside the bay known as a "sand spit," separating the original bay from the open sea and leaving only an opening, which is the current lagoon topography of Dapeng Bay.
