In addition to the delay in repairing the lock wall, a pair of Grey Wagtails have made a nest in a key part of the construction site. The contractors are unable to work near the nest until the young birds have fledged. The earliest date for the lock to re-open is now 21 July. The footpath and canoe portage remain passable.
UPDATE: The fledglings have now flown so the lock is expected to open by 21 July.
