SC Watershed Atlas

Announcing the Enhanced S.C. Watershed Atlas

SCDHEC is pleased to announce the enhanced S.C. Watershed Atlas!  The updated template has more data layers and functions and is mobile-ready. Users can now add data, create layers from selected features, export attribute data, view watershed information at their current location, save their sessions, and restore sessions again later.

Multiple basemaps, search choices, measuring and drawing tools, map making, printing capabilities, and a Help section are still available, making the Atlas a data-rich online tool. The enhancements increase the capacity of SCDHEC’s Watershed Program to facilitate solutions to State water quality issues.
