## What's an Apify Actor?

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md):

```bash
npm install apify-client
```

In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md):

```bash
pip install apify-client
```

In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md):

````bash
# MacOS / Linux
curl -fsSL https://apify.com/install-cli.sh | bash
# Windows
irm https://apify.com/install-cli.ps1 | iex
```bash

In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md).

If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## USGS Water Services Scraper

Extract **real-time water data** from the United States Geological Survey (USGS) National Water Information System — streamflow, gauge height, water temperature, precipitation and more from thousands of monitoring stations across the United States.

The USGS NWIS instantaneous-values service is the authoritative source for live streamflow and gauge measurements used by flood forecasters, water utilities, hydropower operators and emergency managers. This Actor wraps the `waterservices.usgs.gov` endpoint and returns the latest observation for each requested site/parameter as a clean JSON record. **No API key required.**

### Why scrape USGS water data?

- **Flood / drought monitoring**: track real-time streamflow against historical thresholds.
- **Water utilities**: monitor source-water gauges in real time for intake operations.
- **Hydropower**: link discharge data into generation forecasting models.
- **Insurance & reinsurance**: parametric flood products keyed off gauge height.
- **Construction**: monitor nearby gauges during dewatering or site preparation.

### Output fields

| Field | Description |
|---|---|
| `siteCode` | USGS site identifier |
| `siteName` | Station name |
| `stateCode` / `countyCode` / `hucCode` | Administrative + hydrologic unit codes |
| `latitude` / `longitude` | Coordinates |
| `parameterCode` | USGS parameter code (e.g. `00060` discharge) |
| `parameterDescription` | Human-readable variable name |
| `latestValue` / `unit` | Most recent value + units |
| `latestDateTime` | UTC timestamp of latest value |
| `qualifier` | USGS quality flags |
| `observationCount` | Number of points in the returned series |

### How to use

1. Choose a `stateCd` (e.g. `dc`, `ny`, `ca`) **or** a list of specific `sites` **or** a `countyCd`.
2. Optionally adjust `parameterCd` — defaults to `00060` (discharge cfs) and `00065` (gauge height ft).
3. Run the actor.

### Common parameter codes

| Code | Meaning |
|---|---|
| 00060 | Streamflow (cfs) |
| 00065 | Gauge height (ft) |
| 00010 | Water temperature (°C) |
| 00045 | Precipitation (in) |
| 00095 | Specific conductance |
| 63680 | Turbidity |

### Pricing

Pay-per-result. Each `(site, parameter)` series returned = one record.

### Other actors

- USGS Earthquake Scraper
- NOAA Tides Scraper

### FAQ

**Is the data free?** Yes. USGS NWIS data is in the public domain.

**How recent is "real-time"?** Most sites transmit every 15–60 minutes; the actor returns the latest value seen for each series.

**Can I request multiple states?** Run the actor once per state and combine the datasets.

### Legal

Data is sourced from the public USGS NWIS service. The data is in the public domain in the US; please credit "U.S. Geological Survey" when redistributing.

# Actor input Schema

## `stateCd` (type: `string`):

Two-letter US state code (e.g. 'ny', 'ca'). Used when no specific sites are provided.
## `sites` (type: `array`):

Specific USGS site IDs (e.g. ['01646500']). If set, overrides state/county filters.
## `countyCd` (type: `string`):

5-digit FIPS county code (e.g. '36061' for New York County). Overrides stateCd if set.
## `parameterCd` (type: `string`):

Comma-separated USGS parameter codes. Common: 00060 (discharge cfs), 00065 (gauge height ft), 00010 (water temp C), 00045 (precipitation in). Default: 00060,00065.
## `maxResults` (type: `integer`):

Maximum measurement series to return. 0 = unlimited.

  "stateCd": "dc",
  "sites": [],
  "countyCd": "",
