The results of experimental studies of wave turbulence in a system of capillary waves formed on the surface of liquid hydrogen at a tempera-ture of 15 K in a cylindrical cell with monochromatic radially symmetric pumping are presented. The local maximum formation with adecrease in the pumping amplitude was observed for thefirst time in the high-frequency region of the inertial range of the stationary turbu-lent spectrum at the direct cascade edge. The occurrence of a local maximum can be associated with a significant manifestation of viscousdamping in the high-frequency region of the spectrum.
