On October 6, 1334, when the property of the island was located near the Abbasi checkpoint, there was a dispute between the Soviets and Iran over which main branch of the river was in this place. An Iranian officer named Lieutenant Noorullah Kathiri, the planner of the Tabriz Division, was deeply responsible for proving that the branch that was beneficial to Iran was deeper and therefore the main branch was ferocious with his horse. He and his horse disappeared under the waves, but one Iranian border guard, Samad Madadgholi, managed to save the Iranian officer. The Russian delegation, seeing this scene, accepted Iran's ownership of the island 130 in this branch of the river. The island 130 was later named after the approval of the supreme authorities of Iran, and was rewarded with the lieutenant Nourullah Kathiry.
