Pocklington Beck
[12] The beck flows into the Pocklington Canal at Cottingwith at a height of 16 feet (5 m) above sea level, and then the combined waters empty into the River Derwent.[19][20] During the period of the Boxing Day Floods of 2015, Pocklington was not as severely affected as other locations in Northern England, the beck did record its highest level at 2 feet 5 inches (0.73 m).[28] In 2016, a proposal was put forward to build a flood alleviation dam upstream of the town of Pocklington which was approved at a cost of £4.6 million in October 2017.[31] In 2024, Yorkshire Water stated that they would be investing £7.3 million in upgraded the wastewater treatment works at Pocklington to prevent discharge into the beck during periods of heavy or prolonged rainfall, and that phosphorus pollution would be reduced.[33] The native white-clawed crayfish was found to be living in the culverts under Pocklington town when action was being taken to remove gravel and silt from the beck.
