Flood gauges near a point (USGS + NWS)

Nearby USGS stream and river gauges with latest stage and flow observations, plus NOAA/NWS threshold metadata where available, for buyer, owner and lender agents. Hydrologic context only. National by lat/lng or a geocoded address; not a parcel flood prediction, insurance determination, or safe/unsafe label. Use this when you can call Locus free tools (REST tools/call or MCP). Use locus-flood-gauges instead when your client can only call paid x402 routes; it returns the same records. Direct flat-body route for this one free resource; no API key, payment, or catalog wrapper. Return only the cited bounded evidence described here; this route never produces a paid brief or full report.
