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 (https://streamstats.usgs.gov/ss/). These geospatial datasets, along with basin characteristics datasets for Puerto Rico published as a separate USGS data release (https://doi.org/10.5066/P9HK9SSQ), 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 point grid rasters at a 10-m resolution, which are raster representations of the sink points. The value of 1 is assigned to pixels that are sinks. 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 point grid raster was not generated for HUC 21010003 because sinks were not present in this HUC area.
