Nordic reservoir levels today: NVE magasinfylling for Norway, NO1 to NO5
How full Norway's hydro reservoirs are in NVE's latest published week, for the country and each price area, against the same week last year, NVE's twenty-year minimum, median and maximum, and every year since 1995.
Norway's hydro reservoirs were 70.2% full in week 45 of 2026 (2 November to 8 November 2026), according to NVE's magasinstatistikk: 11.3 points below NVE's median for the week (81.6%, 2006 to 2025) and 10.9 points below the same week of 2025 (81.2%). Furthest below its median was NO2 (South-west, Kristiansand), at 54.8%, the lowest of 32 for week 45 since 1995. Above the median: NO4 (North, Tromsø) at 92.1%.

Fill is the share of reservoir capacity filled at the end of the ISO week (2 November to 8 November 2026); changes are in percentage points (pts). The change on the week is computed from NVE's series as it stands now, so it can differ from NVE's own figure when NVE has since revised the week before. The median, minimum and maximum are NVE's figures for week 45. Rank orders week 45 of every year NVE's series holds since 1995. SOURCE: NVE Magasinstatistikk, licence NLOD.

Norway's reservoirs and NVE magasinstatistikk, answered
How full are Norway's reservoirs now? (magasinfylling i dag)
Norway's hydro reservoirs were 70.2% full in week 45 of 2026 (2 November to 8 November 2026), according to NVE's magasinstatistikk: 11.3 points below NVE's median for the week (81.6%, 2006 to 2025) and 10.9 points below the same week of 2025 (81.2%). Furthest below its median was NO2 (South-west, Kristiansand), at 54.8%, the lowest of 32 for week 45 since 1995. Above the median: NO4 (North, Tromsø) at 92.1%.
What is NVE magasinstatistikk?
NVE, the Norwegian Water Resources and Energy Directorate, publishes magasinstatistikk: how full Norway's hydropower reservoirs are each ISO week, as a share of capacity (fyllingsgrad) and in TWh, for Norway as a whole and for the five price areas NO1 to NO5. Its series starts in week 1 of 1995, and NVE also publishes the minimum, median and maximum fill for each week over twenty years. The data is open under the Norwegian Licence for Open Government Data (NLOD), with credit to NVE.
How does the reservoir level compare with 2025?
Lower. Norway stood at 70.2% in week 45 of 2026, against 81.2% in the same week of 2025, -10.9 pts. All five price areas were lower than a year earlier.
Which price area holds the most reservoir capacity?
NO2 34.0 TWh, NO4 21.1 TWh, NO5 17.4 TWh, NO3 8.9 TWh, NO1 6.0 TWh, out of 87.4 TWh for Norway, on NVE's capacity figures for week 45 of 2026. NO2 in the south-west holds 39% of the total, so it moves the national figure more than any other area.
When does NVE publish the reservoir figures?
Weekly. NVE publishes each ISO week's figures, Monday to Sunday, usually on the Wednesday after the week ends. This page re-reads NVE every hour; the latest week it holds is week 45 of 2026 (2 November to 8 November 2026).
What do NVE's minimum, median and maximum mean?
For each ISO week NVE gives the lowest, the middle and the highest fill over twenty years; this week's band covers 2006 to 2025, which this page checked by recomputing it from NVE's own series. A fill below the median is lower than in at least half of those years. The rank since 1995 uses every year in NVE's series instead, and counts only the years it holds a week 45 for.
Does this include Sweden and Finland?
This page covers Norway only, as NVE publishes it. Sweden and Finland publish their reservoir statistics through other bodies, and their figures are not shown here.

Where each figure comes from
Every figure comes from NVE's magasinstatistikk, read from NVE's data service at most once an hour: the whole weekly series for Norway and NO1 to NO5 from week 1 of 1995 to week 45 of 2026, and NVE's minimum, median and maximum for each ISO week. The latest week, its change on the week before, the same week a year earlier, the rank since 1995, the records and the charts are all computed from that one read.
NVE describes its band as covering the last twenty years. This page recomputes the band from the series for each candidate window and names the one that reproduces NVE's published figures for every area: for week 45 of 2026 that is 2006 to 2025. Only some years have a week 53. Checked against NVE's series on 9 November 2026, NVE's week-53 band matched 2006 to 2025, to within 0.01 points, when each year without a week 53 is filled with the mean of its week 52 and the following week 1, and the page shows NVE's band as published. NVE can revise past weeks, so a figure here can differ slightly from NVE's site after a revision.
An ISO week runs Monday to Sunday, and some years have a week 53. A week a year has not got, or that the recorded series does not hold, is shown as missing and never estimated.
