BLACK CYPRESS BAYOU
BLACK CYPRESS BAYOU. Black Cypress Bayou is formed by the convergence of Cunningham and Black Cypress creeks seven miles east of Avinger in southern Cass County (at 32°54' N, 94°26' W). It flows southeast for nineteen miles, through southern Cass County and central Marion County, to its mouth on Big Cypress Bayou, four miles east of Jefferson (at 32°46' N, 94°17' W). The banks of the stream are heavily wooded in places with pine and hardwood trees, and the creek flows through nearly level to gently undulating terrain surfaced by sandy, loamy, and clayey soils used predominantly for timber cultivation and agriculture.
