River Stort

4.6 closure-days per kilometre (95% range 3.7–5.5) — 101 days across 17 closures of this 22km 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 33% of this cruising season — 77 of its 231 days — across 10 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.

1 closure is still shut now, and 1 of those has no reopening date. Filter to it.

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.
