Summary of this months results

The continuing drought conditions are taking their toll on water quality in the catchment, with some total dryback in the upper Bevern. The Bevern Stream at Clappers Bridge gives cause for concern, as this is a holding area for sea trout smolts.

S.O.C.S. and neighbouring Adur conservation society R.A.C.S. are involved in a programme of watercourse habitat restoration as required by the Water Framework Directive, funded by DEFRA and the EU. We fear that unless the problem of deteriorating water quality is robustly addressed, the benefits we expect from our restoration work will be greatly reduced.


Flow observations

At most locations low to no flow were observed with clear and slightly turbid water.
