The Tawe barrage was an early amenity barrage, and studies after its construction showed a deterioration in water quality within the impounded area. The main concern was the effect of low dissolved‐oxygen concentrations upon the migrating salmonids during their passage upstream. An aeration/mixing system was chosen in a combination of diffusers and a propeller, which has proved to be capable of maintaining satisfactory water quality. However, additional diffusers need to be installed to (a) achieve a satisfactory concentration of dissolved oxygen at all points in the river and (b) complete the full scheme.
