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. the finer material ensures that water mainly flows over the ramp, rather than through it. the ramp also enables young eels or elvers to move up the river, and provides habitat for stone loach and bullheads.
