On the International scale of river difficulty the Dyanyshka is a Class II - IV destination for rafting and kayaking.

In its last stretch it flows across a flat area at the edge of the Central Yakutian Lowland where there are many small lakes and marshes.

The river freezes yearly in mid-October and opens in late May or early June.

The river basin has 40 ice fields with a total area of approximately 28 square kilometres (11 sq mi).

Its main tributary is the 179 km (111 mi) long Sagandzha (Саганджа), also known as Byutei-Yurekh (Бютэй-Юрэх),[3] joining it from the left below the northern flank of the Tagindzhin Range.
