Sir - Who is Mr N Taylor kidding, if you take a gallon tin it holds 1 gallon of water approx. 10lbs in weight, if you squash the tin it wont take as much simple to check, so it follows that if our river can only take so much water before flooding then if you dredge it and make it deeper it would carry more water before it bursts its banks simple maths ,It was reported that in some places on the Severn the

Depth is now only tree foot where it used to be twelve foot if that’s correct then you have lost tree quarters of the capacity before flooding.
