Mutford lock links Oulton Broad to Lake Lothing and is the only working lock on the whole of the Broads. Two swing bridges carried the Lowestoft to Ipswich railway line and the A1117 road over the cut to the east of the lock. The road bridge has since been replaced with a single leaf bascule bridge in August 1992. The lock was refurbished in 1992 and was managed by Waveney District Council, but there were discussions taking place in 2009 to transfer it to the Broads Authority, who manage the rest of the Broads. Since 2011, day-to-day management has been handled on behalf of the council by Sentinel Enterprises, which is part of Sentinel Leisure Trust. They also operate Oulton Broad Yacht Station.
