USGS Water-Year Summary 2024

02290888 CHATHAM RIVER NEAR THE WATSON PLACE, FL

LOCATION - Lat 25°42'33", long 81°14'59" referenced to North American Datum of 1983, in T.55 S., R.31 E., Monroe County, FL, Hydrologic Unit 03090202, right bank, 200 yards southwest of Watson Place, approximately 3 mi from the Gulf of Mexico, 10 mi south of Chokoloskee.

DRAINAGE AREA - Indeterminate.

REVISIONS HISTORY - WDR-US-2007, site 02290888, 2006. WDR-US-2008, site 02290888, 2006, 2007. WDR-US-2011, site 02290888, 2010 (daily values discharge).

SURFACE-WATER RECORDS

PERIOD OF RECORD - March 2001 to September 2017, July 2018 to current.

GAGE - Satellite data collection platform with water-stage shaft encoder and acoustic Doppler velocity meter. Datum of gage North American Vertical Datum of 1988 (NAVD88).

REMARKS - Station destroyed by Hurricane Irma on September 10, 2017. Streamflow at this site is significantly affected by astronomical tides. Daily mean discharge was computed from filtered unit values discharge data. The Godin low-pass filter to remove principal tidal frequencies from unit values. Positive discharge (ebb tide) is generally to the southwest direction, and negative discharge (flood tide) to the northeast. Discharge and gage height 15 minutes data, are available in the files of the U.S. Geological Survey. Data can also be accessed online at http://sofia.usgs.gov/. Daily values of gage height and tidally filtered discharge are available online at http://waterdata.usgs.gov/nwis.

EXTREMES FOR PERIOD OF RECORD -

DISCHARGE: Maximum positive discharge, (unfiltered), 13,300 ft³/s Dec. 22, 2018; maximum negative, (unfiltered), 41,300 ft³/s Oct. 24, 2005 (Hurricane Wilma). See REMARKS.

GAGE HEIGHT: Maximum gage height, 5.10 ft Sept. 10, 2017 (Hurricane Irma debris line, +/- >0.4ft); minimum, -2.83 ft Jan. 4, 2008. See REMARKS.

WATER-QUALITY RECORDS

PERIOD OF RECORD -

SALINITY (TOP): March 2001 to January 2015. Discontinued.

SALINITY (BOTTOM): March 2001 to March 2008. Discontinued.

WATER TEMPERATURE (TOP): March 2001 to January 2015. Discontinued.

WATER TEMPERATURE (BOTTOM): March 2001 to March 2008. Discontinued.

INSTRUMENTATION - Water-quality monitor.

REMARKS - Salinity and water temperature sensors were located at -3.9 ft NAVD88 (TOP) and -6.0 ft NAVD88 (BOTTOM). The bottom probe was removed on Mar. 11, 2008 and the top probe was lowered from top position to -4.9 ft NAVD88. During times of missing record, values may have been higher or lower than the listed extremes. Salinity and water temperature, 15 minutes data, are available in files of the U.S. Geological Survey. Data can also be accessed online at http://sofia.usgs.gov/. Daily values of salinity and water temperature are available online at http://waterdata.usgs.gov/nwis.
