Download water level data from USGS using the dataretrieval package. Use when accessing real-time or historical streamflow data, downloading gage height or discharge measurements, or working with USGS station IDs.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# USGS Data Download Guide
## Overview
This guide covers downloading water level data from USGS using the `dataretrieval` Python package. USGS maintains thousands of stream gages across the United States that record water levels at 15-minute intervals.
## Installation
```bash
pip install dataretrieval
```
## nwis Module (Recommended)
The NWIS module is reliable and straightforward for accessing gage height data.
```python
from dataretrieval import nwis
# Get instantaneous values (15-min intervals)
df, meta = nwis.get_iv(
sites='<station_id>',
start='<start_date>',
end='<end_date>',
parameterCd='00065'
)
# Get daily values
df, meta = nwis.get_dv(
sites='<station_id>',
start='<start_date>',
end='<end_date>',
parameterCd='00060'
)
# Get site information
info, meta = nwis.get_info(sites='<station_id>')
```
## Parameter Codes
| Code | Parameter | Unit | Description |
|------|-----------|------|-------------|
| `00065` | Gage height | feet | Water level above datum |
| `00060` | Discharge | cfs | Streamflow volume |
## nwis Module Functions
| Function | Description | Data Frequency |

How to install
mdr add benchflow-ai/benchflow/usgs-data-download@sha256:82f0ec56e7bbfdeaThe line at the top of this page pins the label git:20260610.e2a435f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
