Thompson Water, Carr and Common is a 154.7-hectare (382-acre) biological Site of Special Scientific Interest north of Thetford in Norfolk. [1] [2] Most of it is managed by the Norfolk Wildlife Trust as Thompson Common. [3] It is a Nature Conservation Review site, Grade I, [4] and part of the Norfolk Valley Fens Special Area of Conservation. [5] It is crossed by the Great Eastern Pingo Trail Local Nature Reserve. [6]
This grassland site in the valley of a tributary of the River Wissey has a number of pingos, damp and water filled depressions formed by the melting of ice at the end of the last glaciation. It also has a lake called Thompson Water which, together with its surrounding reedswamp, is important for breeding birds. [7]
The site is open to the public.
