Fet was a municipality in Akershus county, Norway.

The part of Enebakk municipality lying east of lake Øyeren was transferred to Fet in 1962.

The people used long poles with hooks to haul the logs.

The inland river delta that has formed is the largest in Europe and reaches the opposite shore of the lake, across its short axis.

Today, many of Fet's floating buildings have been preserved and converted into a museum and cultural centre.
