About this map:
This map shows the extent of streams and rivers in northern Guam. Surface flow is generally lacking from northern Guam's highly porous, karstified land surface, but does occur in the southern parts of the plateau where high clay content of limestone reduces permeability. The source of geospatial data used is the Bureau of Statistics and Plans (BSP), Government of Guam.
