2025 Map of Cat Island Pass
USGS Topo · Published 2025About this map
Timbalier Island stretches across the eastern edge of this coastal survey, serving as a critical barrier between the open Gulf of America and the sheltered waters of Terrebonne Bay. This maritime environment is defined by its shifting shoals and vital navigational channels, most notably Cat Island Pass, which provides deep-water access between the gulf and the interior bay. To the west, the remnants of Wine Island stand as a marker of the dynamic Louisiana coastline where land and sea are in constant flux. The map documents a landscape almost entirely dominated by water and salt marsh, capturing the sparse remains of the barrier island chain that protects the mainland of Terrebonne Parish from the elements of the open sea.
