# PEGELONLINE Water Levels Scraper (`parseforge/pegelonline-water-levels-scraper`) Actor

Pull live water levels from the WSV PEGELONLINE gauge network across Germany. Each record carries the station name, water body, current level in centimeters, measurement timestamp, gauge zero datum, and coordinates. Ideal for flood monitoring, hydrology research, and shipping logistics.

## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
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.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

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

## 🌊 PEGELONLINE Water Levels Scraper

> 🚀 **Export Germany's live river gauge readings in one run.** Pull current water levels from the full WSV PEGELONLINE network of 700+ active stations.

Turn the official WSV PEGELONLINE service into clean, structured records you can drop into a flood dashboard, a hydrology model, or a shipping planner. Every record is one gauge station with its current water level, the water body it sits on, when the reading was taken, the gauge zero datum, and exact coordinates.

Coverage is the live German federal waterway gauge network as PEGELONLINE publishes it: stations on the Rhein, Elbe, Donau, Weser, Aller, and many more rivers, canals, and tidal reaches, each reporting its latest water level in centimeters. The Actor keeps only stations that actually publish a water-level reading, so you never get empty rows for sensors that measure other things.

| 🎯 Target Audience | 💡 Primary Use Cases |
|---|---|
| Flood and emergency response teams | Track rising levels across rivers in one pass |
| Hydrologists and researchers | Snapshot the national gauge network on a schedule |
| Inland shipping and logistics planners | Watch fairway depths on key waterways |
| Civic and environmental developers | Power maps, alerts, and open-data apps |

### 📋 What the PEGELONLINE Water Levels Scraper does

This Actor calls the public WSV PEGELONLINE REST service and returns one clean record per gauge station that reports a water level:

- **Station identity** — name, UUID, official station number, operating agency, and river kilometer.
- **Location** — water body name plus latitude and longitude.
- **Current reading** — water level value, unit, the exact measurement timestamp, and trend states.
- **Reference datum** — gauge zero value, its unit, and the date it became valid.

You can filter by station name or by water body, control how many records come back, and every record carries a `scrapedAt` timestamp.

### 📊 Data fields

Each record includes: `agency`, `gaugeZero`, `gaugeZeroUnit`, `gaugeZeroValidFrom`, `km`, `latitude`, `longitude`, `measuredAt`, `number`, `scrapedAt`, `stationName`, `trendMnwMhw`, `trendNswHsw`, `unit`, `uuid`, `waterBody`, `waterLevel`. All 17 field names come from a real production run, so what you see here is what lands in your dataset.

### 🚀 How to use

1. Create a free Apify account using [this sign-up link](https://console.apify.com/sign-up?fpr=vmoqkp).
2. Open the PEGELONLINE Water Levels Scraper.
3. Optionally set a `station` or `water` filter to narrow the network.
4. Set `maxItems` to the number of records you want.
5. Click **Start** and grab your results when the run finishes.

# Actor input Schema

## `station` (type: `string`):

Optional. Keep only stations whose name contains this text, case-insensitive. For example 'KOLN' or 'Celle'. Leave empty to return every station.

## `water` (type: `string`):

Optional. Keep only stations on a water body whose name contains this text, case-insensitive. For example 'RHEIN', 'ELBE', or 'ALLER'. Leave empty for all water bodies.

## `maxItems` (type: `integer`):

How many water level measurements to collect per run.
