2024 Map of Grand River
USGS Topo · Published 2024About this map
The Atchafalaya Basin Floodway dominates this landscape along the border of St Martin and Iberville parishes. This area is defined by its complex labyrinth of waterways, where the Upper Grand River and Grand River thread through a dense network of bayous and bays. The map reveals the intricate drainage patterns of the basin, featuring major channels like Bayou Sorrel and Bayou Pigeon. Small landforms such as Big Island and Jack Island emerge from the wetlands, marking higher ground in an otherwise fluid environment. This topography reflects the hydrological management of the nation's largest river swamp, where the interplay of the East Fork Bayou Pigeon and West Fork Bayou Pigeon demonstrates the historical and natural shifts of the basin's interior deltas.
