The Southern Streams are all chalk stream tributaries of the River Kennet that flow in from the south. They include the Dun, the Shalbourne, Froxfield Stream and Inkpen Stream.
The streams receive and convey significant quantities of nutrients and sediment into the River Kennet and the Kennet and Avon Canal.
In 2012 ARK’s Kennet ‘Southern Streams Project’ focused on this area to identify and solve sources of pollution. Most of the pollution is from diffuse sources, and is being addressed through Catchment Sensitive Farming advice. A team of volunteer ‘muddy walkers’ has since collected evidence of sediment pathways reaching the rivers and in 2019 a new Southern Streams farmer group was established with water quality as a principal focus.
A walk-over survey by APEM also identified potential runoff hotspots as well as a handful of point source inputs which are being tackled by Environment Agency enforcement officers.
