US Army Corps of Engineers public datasets — National Inventory of Dams (~91K), levees, locks, docks, FUDS, civil works projects, reservoir pool levels, regulatory districts, and wetland supplement regions.

What is USACE Army Corps of Engineers?

US Army Corps of Engineers public ArcGIS REST FeatureServers and the National Inventory of Dams (NID) bulk CSV. Includes ~91K dams (with hazard class, primary purpose, owner type), ~234 navigable locks, ~20.5K dock points, ~5.6K Formerly Used Defense Sites, ~9.5K civil works projects, ~619 CWMS reservoirs with current pool levels, 39 regulatory district polygons (Section 404 routing), and 10 federal wetland-supplement regions, plus Inland Electronic Navigational Chart (IENC) levee/dam/floodwall geometry. Search by state, county, bbox, or radius; point-in-polygon lookups for districts and wetland regions. Counties returned in Title Case. IENC layers, CWMS reservoirs, and Corps Projects have no STATE column — use bbox/near or rely on the district mapping fallback.
