In this paper, the first observation of the Talbot effect for waves on the surface of a liquid is made. The diffraction of flat surface waves in a ditch with water on a diffraction grating containing 8 slits made it possible to obtain a clear image of the Talbot carpet on the surface of the water behind the grating. The Talbot length observed in the experiment coincides with the data of theoretical calculations.
