Submerged aquatic vegetation (SAV) grows in shallow water areas and includes over a dozen different species. Baltimore County collects SAV data for all creeks where the County maintains a navigation channel. The County has collected SAV data since 1989, analyzing and mapping growth trends. SAV is considered a key indicator of water quality and the general health of a waterway.
