USGS Water-Year Summary 2025
50051310 RIO CAYAGUAS AT CERRO GORDO, PR
LOCATION - Lat 18°09'13.91", long 65°57'24.14" referenced to North American Datum of 1927, San Lorenzo Municipio, PR, Hydrologic Unit 21010005, at downstream side of bridge on State Road 912 at Barrio Cerro Gordo and 2.8 mi (4.5 km) south of San Lorenzo.
DRAINAGE AREA - 10.1 mi². (26.4 km2).
REVISIONS HISTORY -

Datum of gage was previously reported as 525 ft above NGVD 29 and LMSL (OldPR), was established via topographic map. NGVD29 datum does not exist in Puerto Rico and the new PRVD02 datum was revised in October 2022.


SURFACE-WATER RECORDS
PERIOD OF RECORD - October 1977 to current year.
GAGE - Water-stage recorder and crest-stage gage, satellite telemetry at station. Datum of gage is 499.4 ft (152 m) above Puerto Rico Vertical Datum of 2002 (PRVD02). The PRVD02 datum of gage was determined from a GNSS Level 2 single-base static survey of RM-2 (Reference Frame NAD_83 (2011) (EPOCH:2010.000), GEOID18), completed by USGS personnel August 6, 2018. 
Prior to October 1, 1983, at site 2,000 ft (610 m) downstream at different datum approximately 35 ft (10 m) lower. Elevation or datum of gage was previously reported as 525 ft (160 m) above NGVD of 1929 and LMSL (OldPR); established via topographic map. The new GNSS survey was used to establish the PRVD02 datum because the topographic map datum did not meet the new accuracy requirements. This datum was revised in October of 2022.
REMARKS - In past years commercial sand removal occurred at a location 100 ft (30.5 m) below gage, however it has not occurred since the 2009 water year.
CLIMATOLOGICAL RECORDS
PERIOD OF RECORD - October 2016 to current year.
INSTRUMENTATION -

Tipping bucket precipitation gage and data collection platform – 15 minutes interval.
