Llangollen Canal

7.0 closure-days per kilometre (95% range 6.4–7.6) — 526 days across 28 closures of this 75km 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 83% of this cruising season — 192 of its 231 days — across 12 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.

2 closures are still shut now, and 2 of those have no reopening date. Filter to them.

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.
