07369000 Bayou Lafourche near Crew Lake, LA
LOCATION - Lat 32°30'00", long 91°55'05" referenced to North American Datum of 1983, in NW 1/4 SW 1/4 sec.36, T.18 N., R.5 E., Richland Parish, LA, Hydrologic Unit 08050001, near center of span on downstream side of bridge on U.S. Highway 80, 1.1 mi upstream from Illinois Central Gulf Railroad bridge, and 2.5 mi west of town of Crew Lake.
DRAINAGE AREA - 361 mi². Small diversions above station for irrigation. Interconnecting system of bayous and drainage ditches produces an interchange of flow under varying conditions; hence, the drainage limits were more or less arbitrarily determined. Boeuf River and Bayou Lafourche basins are connected by canal upstream. In extreme floods, considerable flow from the Bayou Bartholomew basin passes this station.
