River Hiz

The River Hiz is a small tributary river that feeds the River Ivel that, in turn, feeds the River Great Ouse. Starting at its source of a chalk fed spring just south of the village of Charlton, the river winds its way through the county of Hertfordshire, moving its way into and through Hitchin, where it meets the River Oughton and River Purwell. The Hiz finally meets the River Ivel near the village of Henlow.

The Hiz is a focal point in the town of Hitchin, with a market that takes place historically by its banks. The Hiz also runs past a major (but now defunct) brickworks at Arlesey.

Although small, the Hiz attracts a great deal of wildlife. There are many birds around this area, which include swans, ducks, coot and kingfishers. Fish inhabits the river (trout mainly) and there is also evidence for otters.
