USGS 08012150 Mermentau River At Mermentau, LA

PROVISIONAL DATA SUBJECT TO REVISION

Click to hidestation-specific text
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.

National Weather Service forecast for this station
National Weather Service station , and basin wide forcast.
This station managed by the Baton Rouge Field Office.
