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

02246751 BROWARD RIVER BL BISCAYNE BLVD NR JACKSONVILLE, FL

LOCATION - Lat 30°26'36.02", long 81°40'05.52" referenced to North American Datum of 1983, in sec.02, T.1 S., R.26 E., Duval County, FL, Hydrologic Unit 03080103, in land grant 49, attached to the southeast side of private dock, 0.3 mi downstream of Biscayne Blvd. bridge, 0.6 mi upstream of Harts Road bridge, 6.3 mi from mouth and 7.6 mi north of Jacksonville.

DRAINAGE AREA - Indeterminate.

SURFACE-WATER RECORDS

PERIOD OF RECORD - October 2015 to current year.

GAGE - Water-stage recorder, acoustic velocity meter, and data-collection platform. Datum of gage is at NAVD of 1988.

COOPERATION - This gage is monitored in cooperation with the U.S. Army Corps of Engineers.

REMARKS - Discharge not published some days, due to bad or missing velocity data. 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 was used to remove principal tidal frequencies from unit values. By convention, the U.S. Geological Survey has established ebb (seaward) flows as positive flow and flood (landward) flows as negative flows. The residuals are not total freshwater flows but are a combination of freshwater flows and water storage caused by higher and lower mean sea levels and storm surges from tropical storm events. Instantaneous discharge computed from index-velocity linear regression relation and gage height rating. Daily values of discharge and gage-height are available online at http://waterdata.usgs.gov/nwis.
