What these figures mean
- Population
- Which closures a figure counts. All closures is everything; Unplanned closure drops the works CRT flags as its winter programme and any day outside the cruising season (the Friday nearest 15 March to the Sunday before the first Monday in November). Scheduled work CRT does not flag as winter works still counts here. CRT Planned closure is the flagged winter programme alone.
- Defensible duration
- The days between a closure's start and its reopening date, counted only where the dates allow it. A cancelled notice, or one whose reopening precedes its start, has no defensible duration and is in no total.
- Closure-days
- One day on which one closure was in force. Two closures on the same day are two closure-days; where the question is how long a canal was actually disrupted, overlapping notices are unioned into single intervals. They are counted from 1 May 2025, when this archive begins: a closure that started earlier adds only its days since then, though its own row shows its whole length. Every figure and chart counts only the days inside the Period chosen above them.
- In force
- A closure is in a Period, and a day is one a closure affected, if it was in force at any time that day, including the morning it reopened. Closure-days measure how long, so they count whole days and not the reopening day: a closure can be in a Period and add no closure-day to it.
