The Tukulan has a length of 191 kilometres (119 mi) and a drainage basin area of 2,880 square kilometres (1,110 sq mi).[1] There are no settlements in the area of the river. The nearest inhabited places are Batamay of Kobyaysky District to the west of the Tukulan's mouth and Udarnik, Krest-Khaldzhay and Ary-Tolon of Tompo District to the east.[2]

Course

edit

The Tukulan originates in Lake Ulakhan-Kyuel, a 1.5 km2 (0.58 sq mi) mountain lake of the southwestern Verkhoyansk Range located in Ust-Aldan District. In the upper section of its course the river flows across mountainous terrain, heading roughly southwestwards across the Sordogin Range.[3][4]

After leaving the mountainous area the Tukulan flows approximately in the same SW direction along its middle course. It crosses a floodplain dotted with about 200 lakes where the riverbed divides into slowly-flowing arms. Its lower course is a vast marshy area. Finally the Tukulan meets the right bank of the Aldan River, a little upstream from the mouth of the Kele and downstream of the Baray, 148 km (92 mi) from the confluence of the Aldan with the Lena.[5][3][6] The river freezes between mid October and mid May.[4]

The Tukulan's main tributary is the 98 km (61 mi) long Tuora Tukulan joining it from the right side.[4]
