The sanctuary within the Nanticoke River was
established in 2010 and encompasses 16,600 surface acres. The Nanticoke River
sanctuary is considered a low salinity region (<12ppt). The mean bottom
water dissolved oxygen level within the Nanticoke River is generally above 5 mg/l. These levels are suitable for oyster growth
and survival. There is no reported acreage of submerged aquatic vegetation
(SAV) habitat in the Nanticoke River sanctuary, so no oyster bar acreage
coincides with SAV. A portion of
the sanctuary is classified as a restricted by the Maryland Department of the
Environment (2018) due to potential contamination of shellfish by fecal
coliform and other bacteria.
The Coastal Marine
Ecological Classification Standards (CMECS) bottom characterization from data
collected during the 1970-80’s Bay Bottom Survey and a 2011 side scan sonar
survey conducted by Maryland Geological Survey was used to identify areas of
historic oyster bars that have substrate other than mud.
