Flood gauges near a point (USGS + NWS)

USGS stream and river gauges with latest stage and flow, plus NOAA/NWS threshold metadata within the search radius, for buyer, owner and lender agents. Returns the same records as locus_flood_gauges. Use this when your client can only call paid x402 routes. Use locus_flood_gauges instead when you can call Locus free tools (REST tools/call or MCP).
