Summary:The invention relates to the field of water conservancy project, in particular to a fish passageway and a fish passageway building method of a low-waterhead dam. A submersible hole connecting a high water level side and a low water level side of the dam is formed in a bottom sill of a flood discharge gate, which is close to a power plant, and is used as an outlet of the fish passageway; and a fish passageway body communicated with the submersible hole is built on one side of the flood discharge gate of a spacing wall between the downstream of the power plant and the downstream of the flood discharge gate. By the method, the fish passageway favorable for upstream running is built by ingeniously using the structure of the dam; the submersible hole formed in the bottom sill of the flood discharging gate is used as the outlet of the fish passageway, so that the overall structure of the dam cannot be damaged, and the running safety of the dam is not influenced; and the fish passageway body communicated with the su
