| Summary : Three stone-built Medieval and/or Post Medieval coastal fish weirs were mapped from aerial photographs taken in 1946 and 1999. The fish weirs are located in the intertidal area below Porlock Beach, about 390 metres east of Porlock Weir quay. Constructed from beach pebbles but apparently in poor repair, the weirs are fragmentary in places and barely discernible in others. The stone weirs each consist of two linear arms which spread out to form an inverted V. The apex of the weir faces the sea, trapping fish on the outgoing tide in the pool formed behind by the area cleared of pebbles used to construct the arms. The weir furthest from the shore is a fragment of a stone weir, representing the sluice at the apex, with two very small parts of each arm remaining, the west part being about 8 metres long and 5 metres wide, the eastern part being about 5 metres long and 3 metres wide, with a sluice about 5.3 metres long and 1.5 metres wide. In the middle of the trio, the largest weir is north facing with the west arm about 88 metres long and 3 metres wide. The east arm is around 131 metres long and 1.5 to 7 metres wide and at the apex is a sluice about 8 metres long and 1.3 metres wide. The third weir, closest to the shore, is visible as only fragments of each of the two arms, the west arm section being 58 metres long and 5 metres wide and the east arm section being 29 metres long and 3 metres wide, the central part of the weir and its apex having been destroyed. The fish weirs were still visible in aerial photographs taken in 2005. |
More information : SS 8674 4790. A disused oyster perch.
The perch is an angle of rough boulder walling, about 5m wide, some 90m long on the N side and about 50m long on the W side, built into the boulder-strewn foreshore at Porlock Bay.
A map c. 1710 (a) shows an oyster bank (SS 84 NE 55) in the bay some 850m due N of the perch. The oyster catch was kept in bags until needed in the pond which is formed by seawater retained in the near right-angle of the perch. The perch is shown (unannotated) on the 1889 OS map (b) and as 'Tidal Pond' on the 1973 Revised map (c). It is visible on air photos (d) and at low water. The perch gives its name 'Oyster Perch' to a house built on the coast road in about 1903 for William and Noah Pollard, two local fishermen (e).
1:2500 survey (c) correct. (1)
The remains of three stone fish weirs lie in the intertidal area to the east of the harbour at Porlock Weir. The best preserved is centred at SS 8673 4793. The two arms of the structure of both are constructed of roughly coursed beach pebbles. The western arm is 70m long, 3.7m wide and 0.5m high.The arm is 2.5-6m wide and 0.8m high. The remains of a sluice arrangement 8m long and 2m wide are visible in the `V' of the weir. The remains of a fragmentary fish weir lie 20m to the north of this sluice, centred at SS 8675 4795. It comprises the remains of a sluice in the form of two low stony walls with overall measurements of 20 x 5 x 0.3m. Some 40m to the south of the sluice of the best preserved structure, centred at SS 8675 4788, are the remains of a third fish weir. It comprises two arms of roughly coursed beach pebbles. The western arm is 56m long, 4m wide and 0.5m high. That to the east is 35m long, 5.5m wide and 0.5m high. The sluice gap is 12m long and 10m wide (caused by erosion). The structures were surveyed at 1:2500 scale using differential GPS as part of the RCHME Exmoor project. (2)
Although authority 1 suggests the best preserved structure was built at an oyster perch, there is no reason to suppose that the three structures do not represent the remains of fish weirs. These functioned with the tide, so that as the tide ebbed, the fish would be ponded in the landward side of the weir, and channelled towards the sluice in the `V' of the structure. Here a net or trap would catch the fish. The traps may also have been used to store oysters, as mentioned above. The three here represent successive re-builds of a feature, with the best preserved being the latest in the series. The fish weirs were probably in use in the post medieval period (1a) and were probably abandoned some time in the 19th century. (1b).
Three stone-built Medieval and/or Post Medieval coastal fish weirs referred to above (1-2), were mapped from aerial photographs taken in 1946 and 1999. The fish weirs are located in the intertidal area below Porlock Beach, about 390 metres east of Porlock Weir quay. Constructed from beach pebbles but in poor repair, the weirs are fragmentary in places and barely discernible in others. The stone weirs each consist of two linear arms which spread out to form an inverted V. The apex of the weir faces the sea, trapping fish on the outgoing tide in the pool formed behind by the area cleared of pebbles used to construct the arms. The fish weirs were still visible in aerial photographs taken in 2005.
The weir furthest from the shore is a fragment of a stone weir, centred on SS 8674 4795, being the sluice at the apex, with two very small parts of each arm remaining, the west part being about 8 metres long and 5 metres wide, the eastern part being about 5 metres long and 3 metres wide, with a sluice about 5.3 metres long and 1.5 metres wide.
In the middle of the trio, the largest weir is north facing, centred on SS 8673 4792, with the west arm about 88 metres long and 3 metres wide. The east arm is around 131 metres long and 1.5 to 7 metres wide and at the apex is a sluice about 8 metres long and 1.3 metres wide.
The third weir, closest to the shore, is visible as only fragments of each of the two arms, centred on SS 8674 4788, the west arm section being 58 metres long and 5 metres wide and the east arm section being 29 metres long and 3 metres wide, the central part of the weir and its apex having been destroyed.
