River Welland [SEP] Wildlife
The river, in its upper reaches, supports a wild brown trout population and the occasional grayling. Chub and perch dominate the middle reaches around Stamford, with pike, perch, zander, roach, bream, rudd, ruffe, gudgeon and eels inhabiting the lower lengths around Spalding. A collaboration between the Welland Rivers Trust, the Wild Trout Trust and the Environment Agency has resulted in the construction of a rock ramp, to allow migrating sea trout to pass up the river beyond the weir on the Maxey Cut, which was acting as a barrier. Some 300 tons of rock, with 50 tons of finer material forming a top layer, were used to create the ramp.
