A water current directing unit including an essentially open frame structure for supporting a plurality of flexible, vertically spaced current directing surfaces. Each of the current directing surfaces is inclined slightly upward from the horizontal toward the downstream end of the frame structure causing the water passing over the surfaces to force the unit toward the bottom of the stream, channel, etc. (i.e. to anchor the unit). The upstream edge of each of the current directing surfaces is pivotably attached to the frame structure and each of the corners along the downstream edges is independently moveable in the vertical direction so as to form a curved current diverting surface. A plurality of the current directing units can be positioned in either a series or parallel arrangement so as to effect the desired current diversion.
