Was the outer lock dredged or scoured in Ye Olde Days? We have a few harbours on the Solway, which also has a large tidal range and plenty of mud - which were designed to be washed out by water kept pent up from a burn and then released at low water. Wigtown, Palnackie and Kingholm (Dumfries) all worked this way.
I don`t think they could let too much water out as there are yachts in the top lock! The River Lyd feeds the whole system apart from when Dave allows free flow from the Severn!
