The national trust have put steps and a changing area for swimmers. To access, walk anticlockwise (to the left) of the lake as you face the weir, and almost as you reach the lock keepers cottage you'll see the steps and willow fence change area. Avoid the Weir itself, especially in winter and after rainfall when the water is fast flowing. Swim keeping to edges of Weir pool and avoid the channel from Weir pool to river as there are thick weeds. You'll meet paddle boarders and in season fishermen.
