LOCATION.--Lat 25°45'42", long 80°43'34" referenced to North American Datum of 1927, in T.54 S., R.36 E., Miami-Dade County, FL, 
Hydrologic Unit 03090202, on south bank of Levee 29 Borrow Canal, 100 ft northwest of control structure 12-C, and 33 mi west of 
Miami. No section could be determined from existing maps.

DRAINAGE AREA.--Indeterminate.

PERIOD OF RECORD.--November 1939 to September 1963 (monthly discharge), October 1963 to September 2004, (gage-height and discharge 
record). October 2004 to September 2005. Discontinued. See REMARKS.

REVISED RECORDS.--WDR FL-87-2A, 1986; WDR FL-89-2A, 1983.

GAGE.--Satellite data collection platform with water-stage shaft encoder. Datum of gage is National Geodetic Vertical Datum of 1929.

COOPERATION.--Gate-opening records for S-12 complex provided by U.S. Army Corps of Engineers.

REMARKS.--Records fair except for estimated daily discharges, which are poor. Discharge is the total discharge through the 
S-12 structures A, B, C, and D from Conservation Area 3A. Prior to October 1963 discharge was the total discharge of station, 
Tamiami Canal Outlets, Miami to Monroe (station 02289000). The daily discharge computed from relation between discharge, head, 
and gate openings when flow is controlled by gates and computed by relation between stage and discharge under uncontrolled conditions. 
Satellite data collection platform at S-12-C downstream that records upstream and downstream gages. The total discharge of all four S-12 
stations was published under 02289040 through September 30, 2004. The publication of discharge for each individual  S-12 station started 
October 1, 1985. The upstream S-12-C gage height was published under 02289040 through September 30, 2005. Starting October 1, 2005, the 
upstream stage was published under 02289041 along with the downstream stage and individual discharge for the S-12-C station.
