Also, suitable fish passes could easily provide for the movement of fish and eels.
I agree with P Clark – and why couldn't the barrage accommodate as many wind turbines as possible within the structure and thus reduce the total cost of offshore wind farms in the Bristol Channel?
The building of relatively very small lagoons, such as the proposed Swansea Bay scheme, has always struck me as being very short term when that money could be ploughed into the Severn Barrage.
The Rance Barrage in Brittany has run for more than 40 years and should run for at least another 60, producing guaranteed electricity day in and day out; not like wind turbines that are subject to the vagaries of the wind and are of dubious cost effectiveness with a shorter life span.
Let the discussions continue.

Editor's note: It is indeed a hot topic – more than 400 of you have now voted in NCE's online poll on the Barrage, with 77% of you arguing that, at £14bn, the Severn Barrage is still a better bet than two nuclear power stations.
