River Witham
0.7 closure-days per kilometre (95% range 0.5–0.9) — 35 days across 4 closures of this 51km canal.
Lengths from CRT's ArcGIS open data, published under the strictest reading of its licence. A notice is attributed to the whole named waterway, not to a point.
Something was shut here on 1% of this cruising season — 2 of its 231 days — across 1 separate closures.
That means a closure somewhere on the canal, not that the whole canal was impassable. Every closure below names the locks or bridges it sat between.
Nothing is shut on this canal today.

The season, closure by closure
Each row is one closure. A bar starts and ends where the closure did, and its length is how long it ran; dashed bars have not started yet.

What these figures mean
- Population
- Which closures a figure counts. All closures is everything; Unplanned, in season drops CRT's scheduled winter programme and any day outside the 15 March to 31 October cruising season; CRT winter programme is that maintenance 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.
