        GB 0074 ACC/2423 · Collection · 1760-1978

        Records from the Lee Conservancy Board Engineer's Office at Enfield Lock. The engineer appears also to have been responsible to the Lee Conservancy Catchment Board (for example, see Acc 2423/062).

        The collection consists of nineteenth and twentieth century plans, papers and volumes concerning the Lee Conservancy Board, the Lee Conservancy Catchment Board, and the British Waterways Board, covering many aspects of maintenance work on waterways and administration. The papers comprise:

        • Plans 1760-1954 (ACC 2423/P/0001-3786) A large proportion of the collection consists of plans, many reused with annotations. Items relate to repair work on sewers and buildings, improvements to rivers and pumping stations, and the purchase of land for new projects.
          • Parliamentary Plans 1840-1965 (ACC 2423/PP/001-041) Plans produced for or submitted for Parliamentary Sessions to illustrate forthcoming work on waterways, for example, sewerage work, or waterways affected by the construction of railways.
          • Specific Plans 1867-1964 (ACC 2423/R/001-076) A set of plans illustrating large projects, which seems to have been kept as a set distinct and separate from the main ACC 2423/P plan series by the placing of the letter `R' before each original plan number.
          • General Plans 1828-1974 (ACC 2423/X/001-300) A collection of more general plans relating to projects focusing on improvements to the Lea River and Navigation, the Stort River and Navigation, the Bow Back Rivers and the Grand Union Canal.
          • Ordnance Survey Maps 1838-1955 (ACC 2423/05/001-139) Maps used to plan forthcoming work, with frequent annotations, particularly for the drafting of courses for sewers.
          • Engineers' Reports and Letter Books 1858-1961 (ACC 2423/001-136) Sets of volumes and files recording reports, contracts and specifications, and other maintenance records.
          • Administrative and Legal Documents 1829-1977 (ACC 2423/AL/001-119) Administrative files relating to accidents and damage, together with inventories of assets, minutes of meetings, and engineers' reports. Legal documents include material on agreements for sale and tenancy, the conveyance of property, and contracts.
          • Engineering and Maintenance Records 1892-1978 (ACC 2423/EM/001-097) Records relating to the maintenance and improvement of waterways, including development plans, moratorium surveys, pumping records, and related graphs and operation sheets.
