River Crouch downstream of Wickford Pressures

The table below shows the current pressures that this waterbody faces and the solutions that could be put in place to solve these problems. You can learn more about some of these pressures and solutions on the Environment Agency Catchment Data Explorer or you can contact us to find out more.

PRESSURES

SOLUTIONS

Phosphate levels within this waterbody are considered to be too high and therefore have a 'poor' classification. The point source inputs need to be identified although there is a sewage treatment works that discharges into this waterbody.

Identify point source inputs.

Ensure that sewage effluent standards are maintained.

The diffuse agricultural pollution entering the river within this waterbody is described as 'chronic', there has also been diffuse pollution identified from urban sources.

Engage landowners to encourage best practises for use of phosphates.

Increase riparian buffer strips to encourage nutrients to settle out before entering the river.

Investigate the use of sustainable drainage systems (SuDS) in urban areas.

Signal Crayfish have been most recently recorded on this water body in 2009. Signal Crayfish cause changes to the natural bankside habitat and also out-compete our native crayfish. They are fierce predators and can completely change fish and invertebrate communities so that they are no longer in their natural state.

 There is currently no known solution to the invasion of Signal Crayfish, regular monitoring is needed to ensure a strategic approach when a solution has been identified.
