Description: Data date: 04/27/2021Acquired: 03/23/2023Source: Maryland Department of the Environment, https://mde.maryland.gov/programs/water/DamSafety/Pages/maryland_dam_inventory.aspxThere are over 600 dams in Maryland, ranging in height from six to 296 feet. The Dam Safety Division maintains the Maryland Dam Inventory database, and has developed a KMZ file with selected information from the database for use by the public. The KMZ file can be downloaded and viewed in software such as Google Earth.While the Dam Safety Division makes every effort to maintain an accurate database, this data should not be solely relied upon for emergency decision-making or engineering design purposes. All data, including the dam location and hazard classification must be field verified by the user. The presence or absence of a dam in this inventory does not indicate its regulatory status. All corrections to the inventory should be submitted to the Department's Dam Safety Division with supporting information as soon as changes are known.In addition, there are many thousands of small dams that do not meet the criteria for inclusion in the Maryland Dam Inventory. There are no natural lakes or ponds in the State of Maryland, so all bodies of water exist due to a dam constructed by man or nature (beavers, coastal deposition).For more information, you may call us at (410) 537-3538 or reach us at our mailing address: Dam Safety Division, Water Management Administration, Maryland Department of the Environment, 1800 Washington Boulevard, Ste. 440, Baltimore, Maryland 21230-1708
