Dam ID | Unique SEO Dam ID | Text |
Dam Length | The length, in feet, of the dam which is defined as the length along the top of the dam. This also includes the spillway, power plant, navigation lock, fish pass, etc., where these form part of the length of the dam. | Decimal (10,2) |
Dam Name | Official name of the Dam as shown in the DWR database | Text |
Dam Type | Indicates the type of dam:
Codes are concatenated if the dam is a combination of several types. For example, the entry CNCB would indicate a concrete buttress dam type. |

Downstream Town | Name of the nearest city, town, or village that is most likely to be affected by floods resulting from the failure of the dam. | Text |
Drainage Area | The drainage area of the dam, in square miles, which is defined as the area that drains to a particular point (in this case, the dam) on a river or stream. | Integer |
Drainage Area | The drainage area of the dam, in square miles, which is defined as the area that drains to a particular point (in this case, the dam) on a river or stream. | Integer |
EAP | Indicates whether this dam has an Emergency Action Plan (EAP) developed by the dam owner. An EAP is defined as a plan of action to be taken to reduce the potential for property damage and loss of life in an area affected by a dam failure or large flood.

EAP Inundation Map | Emergency Action Plan included an inundation map. | Text |
Federal Land | Indicates whether dam is a non-federal dam located on federal property. | Text |
Federal Regulations | Federally Owned Dam or private dam subject to federal regulations (i.e. FERC) | Text |
Gage Height | float | |
Hazard Class | Hazard Classification - is the placement of a dam into one of four categories based on the hazard potential derived from an evaluation of the probable incremental adverse consequences due to failure or improper operation of the dam. Conditions for evaluation are absent flooding, and the reservoir is assumed to be full to the high water line. The hazard potential classification does not reflect the current condition of the dam with regard to safety, structural integrity, or flood routing capacity.
