During the X-ray bursts of GS 1826$-$24, "clocked burster", the nuclearreaction flow that surges through the rapid-proton capture process path has topass through the NiCu cycles before reaching the ZnGa cycles that moderate thefurther extent of hydrogen burning in the region above germanium and seleniumisotopes. The $^{57}$Cu(p,$\gamma$)$^{58}$Zn reaction located in the NiCucycles plays an important role in influencing the burst light curves as foundby Cyburt et al. (2016). We deduce the $^{57}$Cu(p,$\gamma$)$^{58}$Zn reactionrate based on the experimentally determined important nuclear structureinformation, isobaric-multiplet-mass equation, and large-scale shell modelcalculations. Based on the isobaric-multiplet-mass equation, we propose apossible order of $1^+_1$ and $2^+_3$ dominant resonance states and constrainthe resonance energy of the $1^+_2$ state. The latter reduces the contributionof the $1^+_2$ dominant resonance state. The new reaction rate is up to afactor of four lower than the Forstner et al. (2001) rate recommended by JINAREACLIB v2.2 at the temperature regime sensitive to clocked bursts of GS1826$-$24. Using the simulation from the one-dimensional implicit hydrodynamiccode, KEPLER, to model the thermonuclear X-ray bursts of GS 1826$-$24 clockedburster, we find that the new $^{57}$Cu(p,$\gamma$)$^{58}$Zn coupled with thelatest $^{56}$Ni(p,$\gamma$)$^{57}$Cu and $^{55}$Ni(p,$\gamma$)$^{56}$Cureaction rates redistributes the reaction flow in the NiCu cycles and stronglyinfluences the burst ash composition, whereas the$^{59}$Cu(p,$\alpha$)$^{56}$Ni and $^{59}$Cu(p,$\gamma$)$^{60}$Zn reactionssuppress the influence of the $^{57}$Cu(p,$\gamma$)$^{58}$Zn reaction anddiminish the impact of nuclear reaction flow that by-passes the important$^{56}$Ni waiting point induced by the $^{55}$Ni(p,$\gamma$)$^{56}$Cu reactionon burst light curve.
