Click to hidestation-specific text
Click to go to the Louisiana Department of Environmental Quality web pages   Data for this site provided through a cooperative program with the Louisiana Department of Environmental Quality.
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 October 1984 to September 2015.
