Stambourne 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.

PRESSURES

SOLUTIONS

Flows are not an issue within the water body but seasonal variations can have an impact on dissolved oxygen.

Continue to monitor to ensure abstraction doesn't begin to have an impact.

Phosphate levels within the brook are high and for this reason is classified as poor.

Dissolved oxygen is also classified as poor with oxygen levels at their lowest in late summer/early autumn. This is due to high temperatures, lower flows and increased aquatic plant growth.

The most likely source of phosphate pollution are sewage treatment works and sewage discharges from private houses.

Further investigations needed to determine the exact source of phosphate pollution. Also discharge points should be monitored to determine their impact on phosphate levels

Further monitoring of dissolved oxygen during normal flow and weather conditions to establish if current results are accurate.

An invertebrate monitoring point has been set up to monitor if dissolved oxygen levels are having an impact on invertebrate populations.

Phosphate levels within the brook are high and for this reason it's classified as poor.

Dissolved oxygen is also classified as poor with oxygen levels at their lowest in late summer/early autumn. This is due to high temperatures, lower flows and increased aquatic plant growth.

Likely sources of phosphate pollution are agricultural run off.

Further investigations needed to determine how weather conditions impact on levels of phosphates and the impact of agricultural inputs.
