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 1973 to September 2015.

Precipitation data for this station are temporary and will only be available for 120 days. (more information) Rainfall monitoring sites maintained by the Louisiana Water Science Center are strictly for operational purposes. Precipitation data are temporary and will not be available following the 120-day display period. Although the instrumentation is calibrated at least once per year, the temporary classification means that documented routine inspections and other quality assurance measures are not performed that would make the data acceptable for archival, retrieval, or future use in general scientific or interpretive studies.
