The River Wey Trust can usually give some guidance on what to do about problems or issues around the river, but - except for the two areas where we own the land adjacent - we have no powers to address any issues.

The Trust is active in oversight of planning and development proposals impacting the river catchment area, working with District and Local Council planning officers. We also monitor the Conservation Area which runs from the Pophole Mill site at Hammer to Headley Mill.
