In this paper, the information paradox on lower-dimensional Gauss-Bonnet gravity known as a three-dimensional EGB black hole is studied using quantum extremal island approach. For that, we connect an auxiliary flat bath system to timelike singularity spacetime and estimate entropy of hawking radiation in its asymptotic regions when weak. The addition areas entanglement wedge causes obey Page curve, shown. surface, or boundary, located outside horizon. This yields time-independent equation for Hawking fine-grained that compatible with appropriate curve. We also discover modifications time.
