The Vorma flows from Lake Mjøsa at the village of Minnesund to join with the Glomma at Årnes.

The "Eidsivating" was, according to tradition, founded by Halvdan Svarte, and served as the 'ting' place for all of the Opplands and Viken.

In 1795 a landslide totally blocked the Vorma at Disen for 111 days, completely drying the riverbed.

On the Vorma, south of Eidsvoll, lies the Svanfoss where the water level in Lake Mjøsa is regulated.

The river cut down until it met the less-easily eroded intrusive sill (part of the Oslo Graben) at the town center of Eidsvoll where it formed the Svanfoss.
