The River Cover is a feeder tributary of the Ure, situated on the East side of the Yorkshire Dales National Park. It drains the local moors before flowing through a picturesque limestone dale, surrounded by ancient woodlands and characteristic extensive dales farms before confluencing with the River Ure 22km downstream.
Throughout the last century the upper reaches of the River Cover were heavily modified and manipulated in an attempt to increase agricultural yield. In conjunction with moorland drainage this has resulted in the river losing a lot of its natural characteristics. This has led to a river that is not reaching its ecological or hydro-morphological potential. Moreover, due to huge improvements in water quality in the tidal Ouse and Humber, since early the 2000s, Salmon have dramatically increased in numbers within the Ouse system and therefore the River Cover has once again become an important spawning site for Salmon.
