No authusace

US Army Corps of Engineers public datasets. No auth. - searchDams (NID, ~91k dams via bulk CSV, 24h cache) - getRegulatoryDistrict (point lookup → 1 of 39 districts for Section 404 routing) - searchLevees, searchLocksAndDams, searchNavigationFacilities, searchFUDS, searchCorpsProjects - getWetlandRegion (point lookup → wetland supplement region) - getReservoirStatus (CWMS — current pool % for flood/conservation/total) Federal scope: dams, levees, locks, navigation, defense cleanup, civil works projects, reservoir pool levels, wetland-rule supplements. IENC layers have no state/county columns — use bbox or near. CWMS reservoirs and Corps projects also lack STATE; state filters fall back to bbox or district mapping.
