Summary:The paper provides the analysis of the state of fish-passing facilities (FPF) on Konstantinovsky, Nikolaevsky and Kochetovsky waterworks facility. The need of construction of a new fish-passing facility on Kochetovsky waterworks facility is especially noted. The authors have offered a new design of a fish-passing facility in the form of the tray connecting the upstream and the downstream. The tray is established in one of the bays of a weir dam. The research results on the influence of the depth atthe beginning of a tray at various gradients at speeds on tray length are presented. The research results are presented in the form of dependences showing functionality of the offered design and the possibility of its use for the pass of fish throu
