Sandon Brook East 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

Himalayan Balsam has been most recently recorded on this water body in 2012. This pretty plant, with pink flowers, is fast growing and hardy. It covers river banks and shades out native plants. In the winter, Himalayan Balsam will die down, leaving bare banks that are susceptible to erosion.

Himalayan Balsam can be removed easily by pulling it from the ground (including the root), snapping the basal stem and then leaving it in a pile to rot down. If you would like to get involved in pulling this invasive species, or would like to organise a work party, then please let us know through the contact us page.

Signal Crayfish have been most recently recorded on this water body in 2012. 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.

Sandon bridge gauging station is a barrier to fish.

Follow the solution listed under fish passage.

The Sandon Brook gauging station has been assessed and it is confirmed to be a barrier to fish but not eels.

Modify the structure to allow fish to pass.

Phosphate levels within this waterbody are considered to be too high and therefore have a 'moderate' 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.

Run off from agricultural land and urban to this waterbody having problems with phosphate.

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.
