The description of the navigable dam structures of the hydrosystem No. 12 “Stakhovo”, methods of field surveys are given. The compressive strength of concrete structures is determined by a non-destructive method using the concrete strength tester IPS-MG4.03. The technical condition of the structure and its mechanical equipment, the presence of defects and destruction of the structural elements of the dam are described. All the most significant structural defects are photographed. Based on the conducted research, recommendations on the repair and reconstruction of the navigable dam were developed
