# USGS water monitoring locations

Finds US water monitoring stations by name, state, county, site type or bounding box: station id, name, county, site type, hydrologic unit, drainage area. Takes name, state name, county name and more, all optional.

Finds US water monitoring stations by name, state, county, site type or bounding box: station id, name, county, site type, hydrologic unit, drainage area, altitude and coordinates. Use it to get the station id for usgs/water-latest-readings, which serves USGS stations only. Name matching is case-sensitive and most USGS names are in capitals, e.g. 'POTOMAC'.

- Tool ID: `usgs/water-monitoring-locations`
- Provider: [USGS](/providers/usgs.md)
- Capability: [Knowledge & research](/tools/knowledge.md)
- Price: no charge per call
- Authentication: an authorised Agentik workspace is required for execution, including zero-price tools.

## Pricing contract

No charge per call. A workspace is still needed so your agent can call it.

## Published example

This is the provider tool’s published example. Replace example values with the user’s requested inputs, respecting the schema; do not execute an example merely to test a connection.


```json
{
  "tool_id": "usgs/water-monitoring-locations",
  "input": {
    "name": "POTOMAC RIVER",
    "state_name": "Maryland",
    "limit": 3
  }
}
```

## Execute and retrieve

Inspect again before execution, explain the price and obtain the required authority. Use MCP run_tool or POST /v1/run with this tool ID, valid input and an idempotency key. Save the returned run ID and follow the actual state. If Agentik answers that the tool is temporarily unavailable, do not retry it blindly; use discovery to propose an alternative.

A partial or uncertain result can still have consumed provider resources. Consult [billing](/docs/billing.md), [idempotency](/docs/idempotency.md) and [asynchronous results](/docs/async.md).
