Mason and its surrounding wetlands occupy a landscape defined by the winding paths of the Boeuf River and Ouachita River. This alluvial plain is crisscrossed by an intricate network of waterways, including Bayou Lafourche and its various cutoffs, alongside numerous brakes and lagoons such as Bushy Lagoon and Thompson Brake. The boundary between Caldwell Parish and Franklin Parish snakes along the river's course, highlighting the geographic importance of these waters in defining local jurisdictions.
