National Inventory of Dams: U.S. Dam Registry with Location and Inspection Data

The National Inventory of Dams (NID) is a congressionally authorized database documenting dams in the United States and its territories. It is maintained and published by the U.S. Army Corps of Engineers and contains information about a dam's location, size, purpose, type, last inspection, and regulatory facts.

Use Cases

• Risk assessment and hazard modeling based on dam location and structural type.
• Infrastructure planning and maintenance scheduling based on last inspection dates.
• Environmental impact studies based on dam purpose and regulatory facts.
• Geospatial analysis of critical infrastructure distribution across the United States.

Strengths

• Authoritative source maintained by the U.S. Army Corps of Engineers.
• Contains multiple documented attributes per dam, including location, purpose, and inspection data.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
