nws/get_water_data
Fetches water gauge data (stages, flows, metadata) from the NOAA National Water Prediction Service (NWPS).
schedule_water_data
Create or update a recurring NWPS water data feed (gauge height, flow). Useful for tracking hydrographs or flood stages over time. Same arguments as nws/get_water_data.

nws/get_water_data
| Name | Type | Required | Description |
|---|---|---|---|
| dashboardId | string | no | Target dashboard/initiative ID. Omit to use the current dashboard. |
| gauge | string | yes | Gauge ID (e.g., "TUSL1" for Tuscaloosa, AL). |
| limit | number | no | Number of observations/forecasts to return (default 50). |
| offset | number | no | Offset for pagination (default 0). |
| summary_only | boolean | no | If true, returns only metadata without observations or forecasts. |
| filter_paths | string[] | no | Optional: Glob patterns to filter output and reduce context usage (e.g. ['observations[*].primary']). |
