Master data / Gauge operator source

The values of this station and the calibration are imported from http://waterservices.usgs.gov/.

The data are automatically imported and the validity and quality are not checked. RiverApp and USGS
are not liable for any errors or omissions in the Information and shall not be liable for any
loss, injury or damage of any kind caused by its use. You always need to check the river state and the navigability by yourself. Recommended “runnable” water levels do not constitute a determination of conditions under which a stream is "safe".

This App is intended as a service to the paddling community and should never be viewed as a substitute for careful river-reading, scouting, and assessment of skills.
