USGS Water-Year Summary 2023
50148890 RIO CULEBRINAS AT MARGARITA DAM NEAR AGUADA, PR
LOCATION - Lat 18°23'40.21", long 67°09'04.32" referenced to North American Datum of 1927, Aguada Municipio, PR, Hydrologic Unit 21010003, on right bank 40 ft upstream of Margarita Dam spillway, 0.2 mi (0.32 km) upstream of Highway 2 at Aguadilla Filtration Plant water intake at Río Culebrinas, 1.05 mi (1.69 km) northeast of Central Coloso, and 2.55 mi (4.1 km) southeast from Aguadilla plaza.
DRAINAGE AREA - 94.6 mi². (245 km2).
REVISIONS HISTORY -

Updated peak gage height and discharge for 2016 water year.

Peaks from the 1998 WY to the 2016 WY were revised using rating 4.0 based on post Hurricane Maria rating. Discharge values were found to be less than the upstream site due to attenuation and ponding from the downstream bridge.

SURFACE-WATER RECORDS
PERIOD OF RECORD - July 1998 to current year.
GAGE - Water-stage recorder, crest-stage gage, and satellite telemetry at station. Datum of gage is 2.4 ft. (0.7 m) above Puerto Rico Vertical Datum of 2002 (PRVD02). Elevation or datum was previously reported as 15 ft. (4.6 m) above mean sea level and NGVD 29 and was established via topographic map and a new GNSS survey was used to establish a PRVD02 datum because the topographic datum did not meet the new accuracy requirements. 
REMARKS - Water is pumped out of the gage pool at Margarita Dam operated by the Puerto Rico Aqueduct and Sewer Authority (PRASA).
