These are the spawning grounds which have been cut off for 40 years by the Pembroke Barrage and the locked sluices at the Mill Bridge.
Until the 1950s salmon sea trout brown trout lamphreys used to spawn here. Eels freely set off to sea and returning elvers thronged the feeder streams. All this ceased with the barrage in the 60s illegally built to provide permanent stagnant fresh water to surround the castle, to cover up the tidal foreshore with water. To attract tourists,BUT sea weed covered foreshore and ever changing mud banks are magic, a haven for wildlife.The Mill Pond was a spawning and nursery ground for thousands of bass and mullet. Three pairs of swans raised cygnets now hundreds of swans foul the stagnant waters and no cygnets survive.PCC spend thousands to create this frequently eutrophic stinking mess.
