We suggest that photons with energies between 5 and 10 MeV, generated by the ({nu},{nu}{prime}{ital p}{gamma}) and ({nu},{nu}{prime}{ital n}{gamma}) reactions on {sup 16}O, constitute a signal which allows a unique identification of supernova {nu}{sub {mu}} and {nu}{sub {tau}} neutrinos in water {hacek C}erenkov detectors. We calculate the yield of such {gamma} events and estimate that a few hundred of them would be detected in Superkamiokande for a supernova at 10kpc distance. {copyright} {ital 1996 The American Physical Society.}
