MDE11716 - East Weir, Lynmouth Eastern Beach (Monument)

"River Lyn fixed engine" dating back to c.1600 comprising two stone walls in a V shape topped with upright posts through which brushwood was woven to create a trap for salmon and sea trout on the falling tide. The fish weir was in operation in 1995 and was owned in 2004 by the Environment Agency. [1] Acutely angled length of stone walling on eastern beach. Marked by the Ordnance Survey as 'East Weir (salmon pool)'. Probably a tidal fish weir. It was visible on an aerial photograph taken in 1978. [2] SS 7238 4994. East Weir, a tidal fish trap or weir, annotated "Salmon Pool" on the 1904 map [3], lies between high and low water marks on the boulder strewn Eastern Beach at Lynmouth. It is formed by a V shaped fence of upright timber poles 1.7 metres high, interwoven with branches. This hurdling is consolidated by a wall at its base constructed of stones. The V points northwest out to sea; its west side is 60 metres long and its north side is 45 metres long. At the point of the V is a concrete and stone sluice with a wooden gate. The whole is in a somewhat dilapidated condition and appears to be abandoned but, according to local sources [4] it is repaired and used annually. [3-5] This coastal fish weir of possible medieval or post-medieval origin can be seen on aerial photographs as a timber revetted earthwork on the foreshore at Lynmouth bay, centred on circa SS 7238 4993 and has been transcribed as part of the Exmoor National Park National Mapping Programme Survey. [4] The weir, or trap, can be seen as an inverted V shape, the point of the V facing northwest, out to sea. As the tide ebbed, the shape of the structure acted as a funnel, trapping fish within a basket or net at the apex of the structure. The weir is clearly visible on aerial photographs of 1946 onwards as the timber structure mentioned above, set as revetment into what appears to be an earthwork base, but may be a wall as described. The structure when in use is probably repaired annually, but the original structure may date to the medieval period or earlier; similar structures elsewhere in Europe have been demonstrated to have been in use since the Mesolithic and the earliest examples in the UK have been found on the Isle of Wight and dated to the later Bronze age. Similar timber structural elements are also visible on West Weir and the numerous weirs recently recorded in Porlock Bay. [4-7] The weir was visible on the 1st Edition Ordnance Survey mapping, as was an associated mooring post located at the point of the V-shape. Both of these were still present on the 2nd Edition map. The structure is still visible on the 2014 MasterMap, where it is recorded as a Salmon Catch; the mooring post is also present and a sluice is recorded. [3,10,11] This record was enhanced as part of the National Record of the Historic Environment to Exmoor National Park Historic Environment Record data transfer project. [12]
