This is the Society Lengthsmen page. 

Around 70 volunteer lengthsmen regularly monitor sections of the Canal, or lengths, to keep an eye out for anything untoward, for example, litter, possible leaks and obstructions to the navigation and towpath. Where the lengthmen cannot deal with any particular problem themselves, they ensure that these issues are reported appropriately.

The whole 32 miles of the Canal are covered by this scheme. Lengthsmen can be regarded as the public face of the Canal Society on the ground.

If you think something on the Canal needs to be reported, or you would like to find out more about the lengthsman role, then please email lengthsman@basingstoke-canal.org.uk.

The Lengthsman Guidance document describes in more detail the role and typical duties of a lengthsman.
