Innis trout fishery
22nd February 2021
The Innis trout fishery near St Austell in Cornwall lies downstream of a large area of former china clay workings. Some of this previously mined land is now being developed into a ‘sustainable new town’ by developer EcoBos. The site groundworks, begun in 2020, apparently both blocked the springs that used to provide vital flows to the fishery, and led to a June 2020 pollution event when sediment-laden water escaped from the works through a road embankment into the stream feeding the fishery, threatening the trout reared on site and preventing fishing for several weeks.
