PROVISIONAL DATA SUBJECT TO REVISION

Click to go to the U. S. Geological Survey's National Streamflow Information Program (NSIP) Click to go to the U. S. Army Corps of Engineers, New Orleans District web pages Data for this site provided by the U.S. Geological Survey's National Streamflow Information Program (NSIP), and through a cooperative program with the U. S. Army Corps of Engineers, New Orleans District.  

Data are tidally affected--Astronomical tides cause significant cycles of approximately 24.84 hours at this site. Because a different portion of the 24.84-hour tidal cycle is averaged in successive daily (24-hour) computations, a systematic secondary oscillation, unrelated to basin hydrology and having a period of about two weeks may be apparent in daily data published from December 1967 to September 2015.
