About this map:
This map shows major ponds and reservoirs in southern Guam. The geospatial data were extracted from the recently updated National Hydrography Database (NHD) by the United States Geological Survey (USGS) in collaboration with Bureau of Statistics and Plans (BSP) and the Water and Environmental Research Institute of the Western Pacific (WERI). The original NHD data can also be viewed and downloaded using the NHD Viewer.
