USGS 07386980 Vermilion River at Perry, 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 1973 to September 2015.
Precipitation data for this station are temporary and will only be available for 120 days. (more information)
