The Peleduy is a left
tributary of the Lena. It has its sources in the southwestern area of the
Lena Plateau. The river flows in a roughly southeastern direction among large boulders within a fairly straight channel. In its middle reaches it bends northeastwards within a
floodplain and not far south of the course of the
Nyuya it bends southeastwards again. Finally it meets the left bank of the Lena by Peleduy village from its mouth.
Tributaries The largest tributaries of the Peleduy are the Mulisma and Kodardakh from the right and the Delinda, Gadala, Kurchakh, Karam and Khoron from the left. The river freezes between October and May.
Permafrost is prevalent in the river basin. ==Flora and fauna==
