LONG ISLAND. Long Island is immediately southeast of Port Isabel between the Port Isabel Channel and Laguna Madre in southern Cameron County (centered at 26°04' N, 97°12' W). The island is 1½ miles long and a mile wide. The Gulf Intracoastal Waterway is to the south and southwest. Queen Isabella State Fishing Pier connects Long Island to South Padre Island. There is some development and settlement on the northwestern shore of Long Island, and a drawbridge connects it to Port Isabel at that point. The soils on the island are composed of sand and mud that support succulents, cordgrass, saltwort, and other grasses. The elevation of Long Island ranges from five feet to twenty-four feet above sea level, and a levee runs north to south on its eastern shore.
