Flood Awareness - Nadder Valley

Updated: Mar 11, 2023

When a Flood Alert is issued by the Environment Agency for the River Nadder, flooding is possible anywhere between Donhead St Mary and Salisbury.

Roads through the parish may be blocked.

Standing water and debris may accumulate. There may be some areas where flood water is present

until it can naturally drain away.


Following heavy rainfall, flooding may affect locations in the Nadder Valley, with low lying land expected to be most affected, particularly around the River Nadder and tributaries between Donhead St Mary and Salisbury.

The Environment Agency is primarily responsible for flood monitoring and notification. If you live in an area or have a property close to the River Nadder or watercourse, check that you have access to and /or register with a flood alert service (see below).

Flooding can be reported to Wiltshire Council using the MyWilts app.

Residents of Sutton Mandeville and Lower Chicksgrove may encounter floods occurring along the C24 (Tisbury - Chicksgrove - Teffont - Dinton road), the lower part of Moor Hill (Panters) and the lane north to Chilmark at Ham Cross. Further flooding may occur through Fovant and along Tisbury Row, meaning that routes across the parish may be blocked to road traffic.
