River Colne upstream of Great Yeldham 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

Flow levels are seasonal and are at their lowest in late summer/early autumn. At this time there may be a negative impact on dissolved oxygen levels.

Investigate if abstraction is having a negative impact.

Phosphate levels are high in this waterbody giving it a classification of bad. The most likely point source causes are sewage treatment works, misconnections and sewage discharges from private housing.

Further investigation is needed to determine the exact sources.

Work with water companies to introduce measure to reduce phosphate entering the waterbody.

Phosphate levels are high in this waterbody giving it a classification of bad. The most likely diffuse causes are agricultural and urban land management.

Further investigation is needed to determine the exact sources.

Sampling to be carried out in winter to determine the impact agriculture has at different times of year.

Give advice to farmers on how to reduce phosphate entering the waterbody through changes in farm practices.
