Geometry Type: esriGeometryPolygon

Description: The Tidal Waters feature class is the geospatial representation for tidal bodies of water (e.g. Chesapeake Bay, tidal tributaries to the Chesapeake Bay, Coastal Bays, and Atlantic Ocean) within Maryland's borders. This feature class is built upon the Chesapeake Bay Program's salinity segmentation scheme and Maryland's coverage for the Coastal Bays. Note: This single feature class is one of a set of feature classes (3) that geospatially depict Maryland's assessment units in non-tidal streams, tidal water bodies, and impounded waters. By linking Maryland's water body use classifications through the common identifier (COMID) code, the information contained in the dataset can be analyzed using software tools ranging from spreadsheets to geographic information systems (GIS) to aid in regulatory decision making. Please note: Where a water body endpoint and use class limit identified in COMAR differed, the segment was assigned the more stringent use class. Five tidal areas on the eastern shore were added by MDE, Water and Science Administration (SSA) staff in June 2017 based on the Maryland SixInchImagery. Modifications were made to the shorelines in those areas to better represent several smaller embayments of Chincoteague Bay and Newport Bay.

Copyright Text: MDE would like to acknowledge the Chesapeake Bay Program for their Chesapeake Bay Segmentation layer which was used during the development of this polygon file. MDE would also like to acknowledge the USGS for their 1:24,000 scale NHD which was used to help determine shoreline extents in tidal waters.
