Lower River Glem 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

Signal Crayfish have been most recently recorded on this water body in 2000 . 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.

 

This waterbody has developed problems with both phosphate and dissolved oxygen levels which both contribute to its overall rating as moderate. Unfortunately there is no data to suggest where these problems are originating from. There are several consented sewage discharges along this waterbody, including one major sewage treatment works.

Carry out further investigation in order to determine the source of pollutants and take the action required to solve the problem.

This waterbody has developed problems with both phosphate and dissolved oxygen levels which both contribute to its overall rating as moderate. Unfortunately there is no data to suggest where these problems are originating from. Reduced oxygen levels are often common in summer months because of reduced river flows, higher water temperatures, increased oxygen demand due to increased biological activity and higher effluent proportions in watercourses.

Carry out further investigation in order to determine the source of pollutants and take the action required to solve the problem.
