  • UPDATE, 11/9: As of November 8, the USGS has successfully restored all of the operational gages that stopped transmitting due to an issue with the satellite telemetry system that records and transmits data. The USGS will now focus on restoring other equipment that experienced the telemetry issues, including about 85 rapid deployment gages that are used periodically for emergency response. Read more

USGS Water-Year Summary 2018
07386880 VERMILION RIVER AT SURREY STREET, AT LAFAYETTE, LA
LOCATION - Lat 30°13'02", long 91°59'34" referenced to North American Datum of 1927, in sec.76, T.9 S., R.5 E., Lafayette Parish, LA, Hydrologic Unit 08080103, at bridge on Surrey Street at Lafayette, 0.6 mi north of Lafayette Airport, and 1.4 mi upstream from Coulee des Poches.
DRAINAGE AREA - Indeterminate.
SURFACE-WATER RECORDS
PERIOD OF RECORD - December 1967 to September 2015, October 2015 to current (Unit values only).
GAGE - Water-stage recorder and acoustic velocity meter. Datum of gage is 2.74 ft below NAVD 88. Prior to Oct. 1, 1985, water-stage recorder for Vermilion River at State Highway 3073, near Lafayette (station 07386935) used as auxiliary gage for this station.
REMARKS -
e: Due to substantial exceedance of verified rating model conditions, the period of record maximum negative discharge is considered estimated. Records fair.
Diversions above and below station for irrigation.
Satellite telemetry and rain gage at station.
Positive and negative flows at this site are defined by direction and are specified to be parallel to the channel at the gage location.
The Positive flow direction is west.
Streamflow at this site is affected significantly by astronomical tides. 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.
EXTREMES FOR PERIOD OF RECORD - Maximum positive discharge, 6,280 ft³/s, July 17, 1989; maximum gage height 17.62 ft, Aug. 15, 2016; maximum negative discharge, -11,300e ft³/s, Aug. 13, 2016; minimum gage height 0.79 ft, Nov. 20, 1969.
