Depth contours are referenced to Mean Pool Level which is definedto be 520 feet above Mean Sea Level (NGVD29).

Contour Interval is 10 feet.

Shoreline is from digital orthophotoquads flown in October 1994 byMaryland Department of Natural Resources. Digitized by USGS.

This work was supported by the City of Baltimore and the Maryland Departmentof the Environment through contract number U00P8000480.
