Water-Year
Summary
instructions
and
information
- Water-Year Summary reports summarize a year of hydrologic data in a printer-friendly format.
- For water years 2014 onward, choose a water year and parameter and an on-demand Water-Year Summary report will be generated.
- For water years 2006 through 2013, choose a water year and an Annual Water Data Report will be provided.
- For water years 2005 and earlier, Annual Water Data Reports may be available in digital format.
- Not all sites have reports available for every water year.
USGS Water-Year Summary 2024
07385790 CHARENTON DRAINAGE CANAL AT BALDWIN, LA
LOCATION - Lat 29°49'23", long 91°32'30" referenced to North American Datum of 1983, St. Mary Parish, LA, Hydrologic Unit 08080102, on the left bank of stream, on wing wall of Southern Pacific railroad bridge over Charenton Drainage Canal, 750 yards downstream of junction with Bayou Teche and six miles upstream of junction with Gulf Intracoastal Waterway
DRAINAGE AREA - Indeterminate.
SURFACE-WATER RECORDS
PERIOD OF RECORD - August 1999 to September 2015, October 2015 to October 2019 (unit values only). Records for 1999 W.Y. are available in Baton Rouge Field Office.
GAGE - Water-stage recorder and velocity meter. Datum of gage is 0.80 feet below NAVD 88 GEOID12a.
REMARKS - Satellite telemetry at station.
No estimated daily discharge.
Records fair.
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 southwest.
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 October 2001 to September 2015.

EXTREMES FOR PERIOD OF RECORD - Maximum positive discharge, 20,600 ft³/s, Jan. 16, 2013; maximum gage height, 6.41 ft, Sep. 13, 2008; maximum negative discharge, -37,200 ft³/s, Sep. 24, 2005; minimum gage height, -1.05 ft, Jan. 6, 2006.
