USGS Water-Year Summary 2024

02290942 LOPEZ RIVER NEAR THE LOPEZ CAMPSITE, FL

LOCATION - Lat 25°47'29", long 81°17'59" referenced to North American Datum of 1983, in T.54 S., R.30 E., Monroe County, FL, Hydrologic Unit 03090204, 0.5 mi northeast of campsite, 2 mi northeast of the river mouth, 4.8 mi from Chokoloskee Island.

DRAINAGE AREA - Indeterminate.

SURFACE-WATER RECORDS

PERIOD OF RECORD - GAGE HEIGHT: April 2001 to January 2015. Discontinued. DISCHARGE: October 2006 to January 2015. Discontinued.

GAGE - Satellite data collection platform with water-stage shaft encoder and acoustic Doppler velocity meter. Datum of gage is North American Vertical Datum of 1988 (NAVD 88).

REMARKS - Streamflow at this site is significantly affected by astronomical tides. Daily mean discharge was computed from filtered unit value discharge data. The Godin low-pass filter is used to remove principal tidal frequencies from unit values. Positive discharge is generally to the southwest and negative discharge to the northeast. Discharge and gage height 15 minute data, are available in the files of the U.S. Geological Survey. Data can also be accessed online at http://sofia.usgs.gov/nwis. Daily values of discharge and gage height are available online at http://waterdata.usgs.gov/nwis.

EXTREMES FOR PERIOD OF RECORD - DISCHARGE: Maximum positive discharge (unfiltered), 6,240 ft³/s Aug. 29, 2011; maximum negative (unfiltered), 9,090 ft³/s Aug. 19, 2008. GAGE HEIGHT: Maximum gage height, 3.52 ft Oct. 24, 2005; minimum, -2.84 ft Jan. 4, 2008.

WATER-QUALITY RECORDS

PERIOD OF RECORD - SALINITY: April 2001 to January 2015. Discontinued. WATER TEMPERATURE: April 2001 to January 2015. Discontinued.

INSTRUMENTATION - Water-quality monitor.

REMARKS - Salinity and water temperature sensors located at -4.0 ft NAVD 88. During periods of missing record, values may be higher or lower than the listed extremes. Salinity and water temperature 15 minute data are available in files of the U.S. Geological Survey. Data can also be accessed online at http://sofia.usgs.gov/nwis. Daily values of salinity and water temperature are available online at http://waterdata.usgs.gov/nwis.

EXTREMES FOR PERIOD OF RECORD - SALINITY: Maximum recorded, 43.5 ppt Apr. 30 to May 1, 2001; minimum recorded, 0.4 ppt Oct. 5,6, 2003, Sept. 13-17, 2006. WATER TEMPERATURE: Maximum recorded, 34.9°C Aug. 5, 2007; minimum recorded, 8.5°C Jan. 11, 2010.
