 The River Crouch Conservation Trust was set up in July 2009 by a group of concerned local people, mainly fisherman, after a stretch of the river around Memorial Park, Wickford was badly polluted.Its aim is to clear the river of rubbish and to bring the river back to a quality which will benefit all forms of wildlife, from water voles, fish to invertebrates and for the benefit of the public.The Crouch Harbour Authority is the statutory harbour and navigation authority for the Rivers Crouch and Roach, extending some distance into the Thames Estuary, and controls both pleasure and commercial use of the rivers.
