School students from north Norfolk have been tasked with designing a new logo to promote a heritage project celebrating 100 years of the Aylsham Navigation.

Aylsham High School students have been asked to help design a logo to be used by the Aylsham Navigation Project in thier work.

The Aylsham Navigation, a 9.5-mile stretch between the town and Coltishall, was closed in August 1912 after floods washed out the five locks and some of its bridges.

From the late 18th century until then, the navigation, part of the Bure valley river system, had been a major route for trade between the two communities and beyond, with wherries travelling its length to deliver and take away goods. It is said that, at the height of the water transport years, 26 wherries were serving Aylsham.

Now, the Aylsham Navigation Project has been launched to commemorate the centenary next year of the navigation's closure, with plans to sail a wherry all the way along the navigation on August bank holiday 2012 and, subject to receiving landowners' permission, a waterside trial from Aylsham to Coltishall and to do a wildlife audit on the waterway.

The group behind the project are looking for a logo to use on things such as paperwork, way-markers and information boards, maps and even some films.

Prizes have not yet been decided, but are likely to be a selection of art and design materials.
