 From Burgh Ferry, boats would use a widened Oulton Dyke to reach Oulton Broad and a new sea lock would be constructed to link the broad to Lake Lothing.This had four sets of gates, so that it could be used at all states of the tide, was capable of holding vessels which were and used a system of sluices to enable the channel through Lake Lothing to be flushed with water from Oulton Broad.Completed in 1829, it was demonstrated in 1831 and although four operations of the sluices were estimated to have removed 10,000 tons of gravel and shingle out to sea, its subsequent operation was not as effective.
