USGS Water-Year Summary 2021
LOCATION - Lat 18°02'41", long 66°12'27" referenced to North American Datum of 1927, Salinas Municipio, PR, Hydrologic Unit 21010004, on right bank upstream side of bridge on State Road 712 and about 0.3 mi (0.5 km) southwest of La Plena.
DRAINAGE AREA - 16.7 mi². (43.3 km2).
PERIOD OF RECORD - January 1973 to April 1979; monthly measurements only, September 1988 to current year.
GAGE - Water-stage recorder, satellite telemetry at station. Datum of gage is 406.72 ft. (123.97 m), above Puerto Rico Vertical Datum of 2002 (PRVD02). Elevation or datum of gage was previously reported as 425 ft. (130 m) above mean sea level and NGVD 29 and was determined via topographic map and a new GNSS survey was used to establish a PRVD02 datum because the topographic map datum did not meet the new accuracy requirements.
REMARKS - Some regulation at low flow upstream from station by local residents for agricultural purposes.
