This mapping tool displays each lease and the corner coordinates associated with the lease. All latitude and longitude coordinates are provided in a degrees, minutes and seconds format and the datum is NAD83 HARN. It may be necessary to convert the coordinates into a different format before entering the information into your GPS unit or change settings on your GPS unit to match this format.

Please note: Leases are issued on a continuous basis throughout the commercial oyster season. A list of leases that have been issued since the beginning of oyster season will be maintained on the left side-bar of this tool in chronological order. You may also download a printable version of the lease coordinates from this tool. If you have questions about the location or status of a shellfish aquaculture lease or would like to request a copy of the printable version of the coordinate document, please contact the Aquaculture and Industry Enhancement Division at (410) 260-8648.

It is a shellfish harvester’s responsibility to be aware of the locations of these leases. Violations of shellfish laws may result in criminal conviction, fine and/or a suspension or revocation of your tidal fish license by a Court or the Department of Natural Resources. Harvesting oysters from a leased area by a person other than the leaseholder or the leaseholder’s official designee is illegal and may result in immediate oyster authorization revocation proceedings under Natural Resources Article, Section 4-1210, Annotated Code of Maryland. Thank you for your cooperation.
