I am writing to tell you about a new and unique lock volunteering role available to residents of Parishes and Towns near to Houghton, St Ives, Godmanchester and Eaton Socon locks on the River Ouse. The role will involve volunteering with the Environment Agency to assist boaters at lock sides and attending waterways festivals. Volunteers will be trained by the Environment Agency and will be given a uniform and ID badge.
The scheme is managed by Cambridgeshire ACRE on behalf of the Environment Agency. You can contact the scheme co-ordinator, Rachael Brown on 01353 865037 or email her at email@example.com.
Rachael is also happy to take any general inquiries about the scheme, what the role involves and how to apply. In addition there is an Anglian Waterways Volunteer scheme website which gives more details about the scheme and how to apply, the link for this is here: https://anglianwaterwaysvolunteerscheme.wordpress.com/
