Nineteen resonances corresponding to excitations between 6.9 and 8.3 MeV have been observed in ${}_{}{}^{17}{}_{}{}^{}\mathrm{O}$+$p$ reactions between $E_p=1400\mathrm{} \mathrm{and} 2800$ keV. From the Breit-Wigner analysis of the excitation function shapes for the various outgoing channels, resonance strengths were obtained and the partial widths deduced. Branching ratios of the $\gamma$ rays were determined and in one case the $\gamma$-ray angular distribution could be measured and used for $J^{\pi }$ assignment. A reaction $Q$ value of 5604±2.5 keV was found.
