What does Vannkart.no show?
Vannkart.no displays measurements from NVE’s national gauging network. Data comes from NVE HydAPI with historical percentiles (p25/p50/p75), showing how levels compare with the seasonal norm.
How to use the measurements
These data can help plan fishing, paddling and outdoor activities. When flooding is possible, always follow official warnings from varsom.no. Measurements may be delayed and should never be the sole basis for critical decisions.
