USGS Water-Year Summary 2023
022907647 LEVEE 31 NORTH EXTENSION AT 1 MILE NEAR WEST MIAMI, FL
LOCATION - Lat 25°44'46.8", long 80°29'51.5" referenced to North American Datum of 1983, in SE 1/4 sec.35, T.54 S., R.38 E., Miami-Dade County, FL, Hydrologic Unit 03090202, (South Miami NW quadrangle), 0.5 mi west of intersection of U.S. Highway 41 and Krome Avenue, and 1.0 mi south of U.S. Highway 41 on the west side of Levee 31 North.
DRAINAGE AREA - Indeterminate.
SURFACE-WATER RECORDS
PERIOD OF RECORD - November 1989 to November 1990, (gage heights only). February 1992 to current year.
GAGE - Satellite data collection platform with water-stage shaft encoder and acoustic Doppler velocity meter. Satellite data collection platform with water-stage shaft encoder and acoustic velocity meter until July 9, 2004, when it was removed. The acoustic Doppler velocity meter was installed May 6, 2004. The acoustic velocity meter and acoustic Doppler velocity meter were run in tandem for the period of May 6, 2004 to July 9, 2004. Datum of gage is 0.10 ft below National Geodetic Vertical Datum of 1929 (NGVD 29) and 1.74 ft below North American Vertical Datum of 1988 (NAVD 88) (FCE bench mark).
COOPERATION - Miami-Dade County.
REMARKS - Discharge computed from relations between stage vs. area and index velocity vs. mean channel velocity. Flow is the sum of regulation from upstream control structures S-334, S-335, and S-336 and from levee seepage and rainfall. Positive flow is to the south and may reverse for short periods. Datum of gage is based upon an adjustment to the RM elevation.
EXTREMES FOR PERIOD OF RECORD - Maximum gage height, 8.17 ft Oct. 15, 1999; minimum, 2.17 ft June 11, 2011.
