Due to what appears to vandalism to the towpath ground paddle above Copper Mill Lock, the lock is no longer able to equalise. Engineers are in the process of determining what is required to fix the ground paddle. We will update this notice on Tuesday 21/04/2026. Copper Mill lock is closed whilst a repair is sought, please moor up safely until further information becomes available. Thank you for your understanding.
