USGS Water-Year Summary 2023
02290768 LEVEE 31 NORTH EXTENSION AT 7 MILE NEAR WEST MIAMI, FL
LOCATION - Lat 25°39'48.2", long 80°29'53.4" referenced to North American Datum of 1983, in NE 1/4 NE 1/4 SE 1/4 sec.11, T.55 S., R.38 E., Miami-Dade County, FL, Hydrologic Unit 03090202, (South Miami NW quadrangle), 0.5 mi west of junction of U.S. Highway 41 and Krome Avenue and 6.9 mi south of U.S. Highway 41 on the west side of Levee 31 North Levee, near West Miami.
DRAINAGE AREA - Indeterminate.
REVISIONS HISTORY - WDR-US-2011: WDR-US-2005, revised estimated discharge 05/11/2005 and 07/15/2005.
SURFACE-WATER RECORDS
PERIOD OF RECORD - June 1994 to current year.
GAGE - Satellite data collection platform with acoustic Doppler velocity meter with acoustic stage sensor. Prior to May 30, 2007, Satellite data collection platform with water-stage shaft encoder and acoustic velocity meter. Datum of gage is National Geodetic Vertical Datum of 1929 (NGVD 29) and 1.67 feet 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 from levee seepage and rainfall, and from structures S-338 and G-211 downstream. Positive flow is to the south and may reverse for short periods.
EXTREMES FOR PERIOD OF RECORD - Maximum gage height, 8.19 ft Oct. 15, 1999; minimum, 2.20 ft June 12, 2011.
