Rived Wid - Mountnessing to Havering's Grove Brook 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.



American Mink have been most recently recorded on this water body in 2011 . American Mink cause a wide range of problems on a river, including playing a large part in the local extinction of many natural species such as water voles and kingfishers.

In order to eradicate mink, they must be trapped and dispatched. Trapping must be done catchment wide as mink can travel large distances. It is important that there are enough people involved in a trapping project to ensure that the traps can be checked regularly. Monitoring mink, water vole and otter presence on your river can also help us when planning eradication

There is no data due to a lack of monitoring within this waterbody.

Collect data in order to determine classification.

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, including a local industrial estate.

The invasive signal crayfish are present in this waterbody. The signal crayfish are likely to be causing problems for invertebrates which have been classified as 'poor' in this waterbody.

There is currently no known method of dealing with signal crayfish, the only next step would be to monitor and manage the population.
