What does Vannkart.no show?

vannkart.no is an independent overview of water levels, discharge and selected additional information from open Norwegian data sources. It is designed for anglers, paddlers, cabin owners, landowners and others following conditions in rivers and lakes.

How to use the measurements

Data comes from sources including NVE HydAPI, Meteorologisk institutt and Vann-Nett. Readings may be missing, delayed or differ between stations; water levels must always be interpreted locally. Use this site for guidance, not as an official flood or safety warning service.

About vannkart.no

vannkart.no collects current water level and discharge readings from NVE and presents them on an easy-to-use map. The aim is to make public hydrological data more understandable, whether you follow a river, check lake conditions or want to see how water changes after rain and snowmelt.

The site is designed for anglers, paddlers, landowners, cabin owners and outdoor enthusiasts. Discharge, water level and water temperature help anglers assess conditions before a trip. Rapid changes, high discharge and changing weather can be important signals for paddlers. Charts show whether readings are low, normal, high or very high compared with the historical normal range for the same time of year.

Water level and discharge are different. Water level is the height of water at a measurement point; discharge is the amount flowing past a point per second. Both are useful, but must always be interpreted locally. A one-metre water level can mean very different things in different rivers. Regulation, ice, rain, snowmelt and local riverbed conditions can affect readings.

Weather data from Yr and Meteorologisk institutt is shown where available, alongside temperature, rain and wind. Public sources include NVE HydAPI, Meteorologisk institutt, Vann-Nett, Miljødirektoratet, Artsdatabanken, Kartverket (place names), OpenStreetMap and Wikipedia. Sources can be temporarily unavailable and readings delayed or missing. Use vannkart.no for guidance and an overview, never as the sole basis for safety decisions.

Important: vannkart.no is not an official warning service and must not be your sole basis for decisions involving danger, floods or emergency preparedness. Data may be delayed or contain errors. Always check Varsom.noand official authorities in these situations.
