Project summary

Edit project overview to modify the project summary.


To restore 520 metre length of the River Tame – re-naturalising the river and improving access for people.

Natural Environment Restoration - The project will restore natural river processes to the River Tame along the eastern edge of Kingsbury Water Park by altering the profile of the current incised river banks and widening the river. This will allow the natural development of riffles which will not only improve habitat but also increase aeration of the Tame and thus water quality. Spoil will be used in Hemlingford Water to shallow the eastern and northern edges, where a reedbed (a BAP priority habitat) will be created separately through Warwickshire County Council’s Higher Level Stewardship agreement (HLS), to increase biodiversity and prevent erosion at the edge of the lake from boat wash.

Improved Access - The re-profiling work will enable walkers using the footpath between Hemlingford Water and the River Tame to see the river which is at present hidden by a mound of dredgings. Access will be created on the left bank and improved on the right bank of the river. There will also be improved safety for locals who swim/paddle in the river.

A ramp will be created (from the spoil) to allow access from the raised walkway at the northern end of the site to the right bank of the river. This will create a circular walk along both banks of the Tame between the two bridges.

Monitoring surveys and results

Edit project overview to modify the Monitoring survey and results.


  • WFD Baseline data
  • Fixed point photos before and after
  • Aerial photos before and after
  • river profile survey taken before

Bioblitz identified good fish stock eg lots of predatory fish. Lots of Bullhead, an LBAP species which is sensitive to water quality and European Eel a protected species.

Botanical survey showed natural regeneration of floodplain meadow indicator species eg Greater Burnett.
