Zusammenfassung:	PURPOSE:To form an artificial fishing ground and restore a river after scouring by arranging, in a watercourse, an integrated structure provided with walls in at least three directions and artificially welling forth water in the depths. CONSTITUTION:An integrated structure 1 provided with walls, for example, in three directions is arranged on the bottom of a watercourse. At this time, a plane V shape is formed for respective directions of flow A, B, C by an intersection point formed by at least two walls. The watercourse flow is disturbed and a vortex is made by the wall surface of the integrated structure 1. Simultaneously, the watercourse flowing direction is changed and a high ascending current of more than ten times is formed. Furthermore, the scale and the height of the ascending currnt is adjusted by freely selecting the heights L and the opening angles alpha of the respective walls. Thus water in the depths rich in nutritive elements can be welled forth and a new fishing ground can be made up.
