About this map

Extension sits at the heart of this landscape, positioned between the winding courses of the Boeuf River and the Quachita River in the early 1980s. The area is defined by its complex hydrology, where an intricate network of waterways like Grayson Bayou and Duck Creek feed into numerous oxbow lakes and basins. The topography reveals the natural drainage patterns of the Prairie, showing how the land transitions from the elevated banks near Extension toward the low-lying wetlands of Turkey Creek Lake on the eastern edge.

Water dominates the local geography, with distinct features such as Rabbit Island and Cocklebur Island situated within the river bends. This survey documents the parish line where Franklin Parish meets Catahoula Parish, tracing a boundary through a labyrinth of named water bodies including Sunk Lake, Hickory Lake, and Dry Lake. The presence of several wells across the terrain suggests the importance of subsurface resources alongside the established river-based transportation and drainage system.
