The River Witham will be raised to its summer level at the end of March so access to the Slea will then be possible for all craft.
Would all boaters please note that the winding hole below Cobblers Lock has now been cleared. Boats should turn in the by-wash which comes out on the right hand side about 100m below the lock. Do NOT make the mistake of trying to turn in the Old Slea which joins the Navigation from the left as it is very shallow.
Boats should reverse into the by-wash and let the flow take the bow round.
Please also note that Halfpenny Hatch bridge is low and air draft varies with river level and flow. However, when a boat passes through Bottom or Taylors Lock a rough idea of the clearance at Halfpenny Hatch Bridge can be found by looking at the white painted mark on the right hand support of the guillotine gate. The Trust takes no responsibility for the accuracy of the marking, which is for guidance only, but this is approximately at the same height as the underside of the bridge deck. If the top of your boat is close to the level of the mark, then be very careful when attempting to negotiate the bridge.
