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
02290769 CANAL 111 AT S-18-C NEAR FLORIDA CITY, FL
LOCATION - Lat 25°19'38.0", long 80°31'29.4" referenced to North American Datum of 1983, in NW 1/4 sec.03, T.59 S., R.38 E., Miami-Dade County, FL, Hydrologic Unit 03090202, about a quarter mile south of control structure 18-C, and 8.5 mi south of Florida City.
DRAINAGE AREA - Indeterminate.
REVISIONS HISTORY - WDR FL-78-2A,1974-77. WDR-US-2012, site 02290769: WDR-US-2009, revised discharge figure for Sept. 10, 2009.
SURFACE-WATER RECORDS
PERIOD OF RECORD - October 1968 to current year.
GAGE - Satellite data collection platform with water-stage shaft encoder and acoustic Doppler velocity meter. Prior to September 30, 2001, satellite data collection platform with water-stage shaft encoder and acoustic velocity meter. The acoustic velocity meter and acoustic Doppler velocity meter ran in tandem for the period of May 24, 2001 to October 17, 2001. Datum of gage is National Geodetic Vertical Datum of 1929 and 1.57 ft below the North American Vertical Datum of 1988 (U.S. Army Corps of Engineers bench mark).
COOPERATION - Gate-opening recorder data and slot operations record provided by South Florida Water Management District upon request.
REMARKS - Records good except for estimated and negative daily discharges, which are poor. Flow regulated by S-18-C. Prior to November 30, 1992, discharge computed from relation between head and gate openings at S-18-C. After December 1, 1992, discharge computed based on continuous record of stage and velocity at newly established acoustic velocity meter site downstream of S-18-C. Discharge computed from relations between stage vs. area and index velocity vs. mean channel velocity. Prior to the 1993 water year, the downstream gage height is available in files of the U.S. Geological Survey under station number 02290770. Starting with the 1993 water year, the downstream gage height is available in files of the U.S. Geological Survey under station number 02290769. Prior to the 1994 water year, discharge published under the name Canal 111 Above S-18-C found under the same station number (02290769). Prior to December 1, 1992, digital water-stage recorders, electromagnetic velocity meter recorder, and a dual graphic water-stage and gate opening recorder were operational.
EXTREMES FOR PERIOD OF RECORD - EXTREME UPSTREAM STAGE(1969-92): Maximum gage height, 3.62 ft July 24, 1985; minimum, -1.53 ft estimated May 14, 1971.
EXTREME DOWNSTREAM STAGE(1993-current year): Maximum gage height, 4.64 ft Sept. 10, 2017; high water mark elevation of 4.66 ft Oct. 24, 2005, occurred during Hurricane Wilma event; minimum, 0.13ft May 19, 2002.
