`hydrometric_realtime`

Pack: weather-gc-ca · Endpoint: https://gateway.pipeworx.io/weather-gc-ca/mcp

No MCP client? Call it directly: GET https://gateway.pipeworx.io/v1/tools/hydrometric_realtime for the schema, then POST the same URL with its arguments for the data.

Real-time water level (metres) and discharge/flow (m3/s) readings from Water Survey of Canada gauges, typically every 5-15 minutes and covering the last 30 days. AUTHORITATIVE for “how high is the right now” and for flood watching in Canada. Pass a station number from hydrometric_stations_near, e.g. “02HC003” (HUMBER RIVER AT WESTON), or give latitude/longitude to get the most recent readings from every real-time gauge in the area. Readings come back newest first.

Parameters

Name	Type	Required	Description
`station_number`	string	no	Water Survey of Canada station number, e.g. “02HC003”. Get one from hydrometric_stations_near.
`latitude`	number	no	Latitude, used instead of station_number to sweep an area, e.g. 43.65.
`longitude`	number	no	Longitude, used with latitude, e.g. -79.38.
`radius_deg`	number	no	Half-width of the area sweep in degrees (default 0.5, max 5).
`start_date`	string	no	Optional start of a time window, YYYY-MM-DD, e.g. “2026-09-10”. Data goes back 30 days.
`end_date`	string	no	Optional end of the time window, YYYY-MM-DD, e.g. “2026-09-17”.
`limit`	number	no	Max readings to return (default 20, max 200).
