Welcome

Running steeply from Dartmoor National Park to the South Devon coastline, the River Yealm is tranquil and cherished, designated by the Environment Agency as one of only 42 Principle Salmon Rivers within England. Much of the surrounding land is owned by the National Trust, whilst also including a Special Area of Conservation (SAC), bass nursery and Site of Special Scientific Interest (SSSI), harbouring many protected species.

 

However, our river is under threat. Only 12 miles long from moor to sea, it is subject to outputs from as many as 9 sewage treatment works, 2 China clay works, agriculture, landfill, aggregate recycling works and 2 business parks.

In response, the River Yealm Water Quality Group (RYWQG) was convened in 2022, comprised of representatives from each of our seven riparian Parish Councils (Brixton, Cornwood, Ermington, Newton & Noss, Sparkwell, Wembury and Yealmpton), including local people and organisations concerned about river water quality.

Our aim is to help preserve ecological health, fish stocks and amenity value, including local businesses such as a shellfish farm.

Current highlights​

 

Specific areas of concern

  • On the Yealm River, there is an urgent need to reduce significant inputs from industry, sewage and/or surface runoff to three tributaries that include the River Piall, Lee Mill Stream and Long Brook Stream, as well as to the main channel between The Borough and Puslinch Bridge, spanning Yealmpton sewage works. 

  • Within the Yealm Estuary, there is an urgent need to identify and act upon significant pollution from tributaries that include Newton Stream, Ridgecott Lake Stream, Coffin Stream and Noss Mayo Stream.

Our emphasis is upon working collaborations

 

Acting upon pollution events

​​

  • Reporting on how a critical release of China clay-like material in Dec 2022 smothered the beds of Rivers Piall and Yealm during winter months when fish eggs normally develop; and 

  • Engaging with local authorities concerning multi-stage plans to remediate a major spill of tributyl tin and other metals below the former AkzoNobel paint-testing laboratory.

Catchment wide planning

  • Guiding local Parish Councils on planning applications involving disposal of surface water, to help ensure runoff does not overload sewage treatment works.

  • Supporting an application to DEFRA for "bathing water status"; and

 

  • Working with other organisations on our River Yealm Catchment Plan, helping to coordinate collective schemes towards addressing areas of concern.
