Historic England Level 1 Photographic Survey carried out on outlet tunnel and tailbay culvert at Burnhope Reservoir, Wearhead, Co. Durham prior to works being undertaken. A complete archive of digital photographs from the survey will be deposited with Archaeological Data Services (ADS) and a copy of the report with Durham County Council Historic Environment Record. This report and the archive are considered a complete record of outlet portal, and no further work was recommended.
