2020 Map of Collicon Lake

About this map

Collicon Lake and the vast marshes of Cameron Parish define this coastal landscape, where the land and water are inextricably linked through a complex system of natural bayous and man-made canals. In the northeastern portion of the quadrangle, the Blackfish Canal and Round Lake Canal illustrate early water management and navigation efforts near Blackfish Bay. The southern half of the map is dominated by expansive wetlands interspersed with named high points such as Eagle Island, High Island, and Twin Island, which likely served as critical refuges in this low-lying terrain. The transition from large open water bodies like Grand Lake to smaller, locally named basins like Petit Lac L'Huit and Grand Lac L'Huit reflects the intricate hydrology of the region. This 2020 survey documents the modern extent of these coastal features, from Lake Benoit in the west to the winding course of Coon Mound Bayou in the east.
