Abstract
A spur dike type fishway inlet includes an upstream flow block wall, an extra water supply nozzle, and an artificial fish reef. The upstream flow block wall is arranged upstream of a fishway inlet; the starting end of the upstream flow block wall is connected with the upstream side wall of the fishway inlet through a connecting shaft and a hydraulic strut. The extra water supply nozzle is installed in the fishway inlet and is connected to the upstream of a power station through a pipeline to directly supply water to a high water head. The artificial reef is set up within the shielding range of the upstream flow block wall.
