Bay Grasses

Bay grasses—also known as submerged aquatic vegetation, or SAV—are plants that grow in the shallow waters of the Bay, providing food and habitat for fish, crabs and waterfowl. More than 16 species of bay grasses grow in the Bay and its tributaries.

These bay grasses grow in the fresh waters of the upper Chesapeake Bay and the Bay's streams, creeks and rivers. Some may also grow in non-tidal waters such as ponds, lakes and reservoirs.


These bay grasses grow in slightly or moderately brackish waters in the middle Chesapeake Bay and the Bay's rivers.


These bay grasses grow in the salty waters of the lower Chesapeake Bay and its rivers.
