FIELD: water surface cleaning of ice, particularly fish saving measures, namely aimed at air holes and non-freezing ice holes creation in countryside territories.
SUBSTANCE: method involves removing ice from water reservoir surface by supplying water from bottom layer of water reservoir to upper one through pipeline so that ice-hole is created. The pipeline is made as closed loop resting upon telescopic supports provided with floats so that the pipeline is submersed in water and top pipeline surface levels with water surface. The pipeline is communicated with bottom water layer from the first pipeline loop side by means of intake pipe. Another pipeline loop side is communicated with inclined water discharge pipeline extending in downstream direction. Outlet orifice of inclined water discharge pipeline is arranged below water level of water reservoir.
EFFECT: possibility of water surface cleaning without human aid.
