On the river at City Mill

Low, clear water makes fish wary, and anglers often do better early and late in the day. For canoeists, shallow riffles mean scraped hulls and the odd portage.

Flood warnings for the area come from the Environment Agency.

About the River Itchen

River Itchen, Hampshire

The River Itchen in Hampshire, England, rises to the south of New Alresford and flows 26 miles (42 km) to meet Southampton Water below the Itchen Bridge. The Itchen Navigation was constructed in the late 17th and early 18th centuries to enable barges to reach Winchester from Southampton Docks, but ceased to operate in the mid-19th century and is largely abandoned today.
