Reservoir holdings feeding the Northampton Arm are lower than normal for the time of year. This is a result of the prolonged dry weather, water loss through evaporation during the heat wave, and, in some instances, paddles being left open or leaks in the infrastructure.

To help us conserve water and maintain safe navigation, we will be closing the Northampton Arm to passage from 3pm on Monday 27th July. Lock 1 and 12 will be locked.

The situation is being continually monitored and reviewed; however, we encourage all boaters currently on the Arm to consider moving to the main line while navigation remains possible. We will update this notice as the situation develops.
