Various theories beyond the standard model of particle physics predict theexistence of baryon number violating processes resulting in nucleon decay. Whenoccurring within an atomic nucleus, such a decay will be followed by secondarydecays of the daughter nucleus unless its ground state is directly populated.In this paper, we estimate branching ratios for processes associated withdinucleon decays of the $^{16}$O nucleus. To this end, we use a simple shellmodel for the ground state of $^{16}$O. For decays from the 1$s_{1/2}$configuration, which result in highly excited states in the daughter nucleus,we employ a statistical model with the Hauser-Feshbach theory. Our analysisindicates that the branching ratio for gamma-ray emission in the energy rangebetween 5 and 9 MeV, which is relevant to low-threshold water Cherenkovexperiments such as SNO+, is 4.53%, 35.7%, and 20.2% for the $nn$, $pp$, and$pn$ decays in $^{16}$O, respectively. In particular, emission of 6.09 MeV and7.01 MeV gamma-rays from $^{14}$C, and 6.45 MeV and 7.03 MeV gamma-rays from$^{14}$N, have branching ratios as large as 10.9%, 20.1%, 7.73% and 8.90%,respectively.
