Abstract

This paper presents a summary of the Ohkohchi Temporary Denil Fishway Project. In this project, a small, but long and steep Denil fishway has been installed on a temporary spillway channel at the Ohkohchi sabo-dam. After the failure in the initial design of twin-line fishway with shallow resting pools, trials of various devices to improve the fishway and evaluation study have been carried out since 1993. The major improvement includes changing to a zigzag single-line system resulting in a change of flow direction in each pool and the addition and modification of resting pools. After these changes, successful ascent of the fishway by some fishes was confirmed.
