Full Description

The present dock at Porlock Weir was under construction in 1855 by Colonel Blathwayt. This was created when it was thought that there were valuable minerals on Exmoor; a railway was proposed to run from Simonsbath to Porlock Weir. Nothing really came of the mines and railway (MSO7906) which would have altered the small dock considerably. A very comprehensive schedule of dues for goods, imported and exported, was drawn up - so detailed that it seems likely to have been copied from another existing port. The harbour consists of a small basin enclosed by pebble banks on one side and the land on the other with a single lock gate at the south end. The gates are rarely used now as trade is very small. [1] SS 86394796 A dock at Porlock Weir*. Worthy Stream, which now flows into the sea about 500 metres to the northwest of Porlock Weir, was thought originally to have flowed into Porlock Weir Harbour [2]. Shown on a map [3] of c. 1710 the dock is annotated "The Basin or Weir Dock" and appears to have a stream flowing into it from its western end. The first harbour at Porlock Weir may have been built by the 15th century as accounts of 1422/23 are quoted for "the repair of the Weir at West Porlock" [2]. Porlock Weir was a fishing harbour until the 19th Century when the entrance was improved to take cargo vessels of 12 foot draught [4]. Lock gates were added so they could be unloaded at any state of the tide. The quay and lock are shown on the 1841 Tithe Map [5]. At one time quite sizable vessels, up to 100 tons, came into Porlock Weir [2] and there was a flourishing trade with South Wales, bringing in coal, limestone and cement and exporting agricultural produce, tan bark, charcoal and pit props [4]. The dock was formed by building a stone quay and lock with a single gate across the southern end of a natural channel (the old course of the Worthy Stream?) between the bottom of the coastal slopes and the western end of the massive shingle bank which skirts Porlock Bay. The present lock gates (of timber and iron) replaced the previous pair in about 1913 [2]. When the lock gates are closed a pool of water some 350 metres long by 70 metres at its widest (about 1.5 hectares) is formed. There was a footbridge at SS 8636 4803, but this has now gone; though it is possible to walk across the mud-covered shingle bottom of the dock when the lock gates are open at low tide. There is also a footbridge across the top of the lock gates for access to the quay. The harbour used to be sluiced through a tunnel (no longer used), the sluice being controlled from a stone building on the quay [2]. Now, at low tide, the lock gates can be used as sluices to let water scour the entrance channel [4]. The harbour is now used largely for pleasure craft. * Note: Porlock Weir is called 'Porlock Quay' on an estate map of 1809-12 [6] [7]
