The reaction ${}_{}{}^{70}{}_{}{}^{}\mathrm{O}$,2p2n${)}^{82}$Sr with E${(}^{16}$O)=80 MeV was used to study the nucleus ${}_{}{}^{82}{}_{}{}^{}\mathrm{Sr}$. Measurements were made of the excitation functions, angular distributions, and γ-γ-t coincidences. From these measurements six new levels were placed in the level scheme of ${}_{}{}^{82}{}_{}{}^{}\mathrm{Sr}$ at 2683.7, 3609.2, 4367.1, 5308.4, 6364.4, and 7827.8 keV. A gamma ray with a very high anisotropy [$A_2$=-1.05(7), $A_4$=0.12(6)] feeds the ${(11\mathrm{}}^{\mathrm{-}}$) level at 5914.5 keV. A new band based on the level at 3525.7 keV was identified. The sequence of transitions decaying down the negative parity band was reordered to 522-1005-876-694 keV.
