With prolonged dry weather, a navigational drought is more likely. The water management team work hard to prolong the time the canal can be used for boating. This may mean we have to limit the hours which the boats can travel through locks during the day.
When we are in a drought we monitor reservoir levels and the groundwater allocations we have. On a weekly basis we undertake modelling to help us decide when we may have to close the canal to navigation, or restrict boat movements to keep the canal open for longer.
