Southern Guam geospatial information server
About this map:
This map shows the topographic divides that represent the boundaries of the watersheds in southern Guam. The geospatial data were derived from the watershed boundary dataset which was obtained from the Bureau of Statistics and Plans (BSP) and (likely) originated from the Natural Resources Conservation Service (NRCS). As this is an older dataset, boundaries were likely derived by digitizing USGS topographic maps. An official update of the watershed boundaries between BSP and NRCS is pending.
