Плесецкий район
The river basin of the Yemtsa occupies the east of the Plesetsky District, the south of the Kholmogorsky District, and some areas in the northern parts of the Nyandomsky and Shenkursky Districts. In addition, the territory subordinate to the town of Mirny lies entirely within the limits of the river basin of the Yemtsa. In the low course, the Yemtsa bounds from the south the Siysky Zakaznik, a federal nature protected area.
