Sink watershed rasters for Puerto Rico StreamStats

Metadata Updated: October 29, 2023

The U.S. Geological Survey (USGS), in cooperation with the Puerto Rico Environmental Quality Board, has compiled a series of geospatial datasets for Puerto Rico to be implemented into the USGS StreamStats application ( These geospatial datasets, along with basin characteristics datasets for Puerto Rico published as a separate USGS data release (, were used to delineate watersheds and develop the peak-flow and low-flow regression equations used by StreamStats. The geospatial dataset described herein are the sink watershed grid rasters at a 10-m resolution. A value is assigned to pixels in each sink watershed and the count of cells that drain to that sink. Data are partitioned into three TIFF files, for three of the four 8-digit Hydrologic Unit Code (HUC) areas for Puerto Rico: 21010002, 21010004, and 21010005. A sink watershed grid raster was not generated for HUC 21010003 because sinks were not present in this HUC area.
