The article shows the results of the analytical review of the main floating structures used in the water supply channels. It is noted that there are two classes of floating constructions: active - affecting the flow regime and changing its structure in the selected direction (floating regulators, jetting devices for changing the flow structure); passive - eliminating the adverse effect of flow ingredients on the elements of the hydraulic unit of the pumping station, without changing its structure and parameters (debris deflector, aero curtain). The basic requirements for the design of floating devices are formulated: reduction of hydraulic losses (streamlining of pontoons and fenders) increase of stability, durability, maneuverability of conditions for installation on water ensuring the water tightness of hermetic compartments, the possibility of balancing and repair, increasing functional reliability and efficiency. A fundamentally new design of the structural elements of the water supply channel has been proposed to help reduce the flow of both bottom and suspended sediments to the mainstream of the water supply channel.
