Bumpstead 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.



Signal Crayfish have been most recently recorded on this water body in 2003, 2005 and 2014. 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.


Phosphate levels are also impacted by the local sewage treatment works which discharges in to this waterbody.

The discharges from the sewage treatment works should be monitored.

Phosphate levels in this waterbody as currently classified as poor. This phosphate is likely to be coming from diffuse agricultural sources.

Engage with landowners to try and reduce phosphate use, or run-off risk.

The invasive signal crayfish are present 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.
