What is a watershed?
How can the concept of watershed be used to improve water quality?
The Barataria-Terrebonne National Estuary Program area is a watershed.
The boundary of the BTNEP watershed is delineated by man-made divides called levees and the Gulf of Mexico. On the east side is the west guide levee of the Mississippi River; on the west side is the east guide levee of the Atchafalaya River; on the north side is the south levee of the Old River Control Structure; and on the south side it is bounded by the Gulf of Mexico. Major land uses with the BTNEP watershed are row crop agriculture (sugarcane, soybeans, and corn), urban, bottomland hardwood forests, deciduous wetland forests, and some aquaculture.
