Poronay in Depth
Geography
The river begins on Mt. Nevel in the East Sakhalin Mountains, flows south through the swampy wetlands of the Tym-Poronay Valley, and enters the Sea of Okhotsk in the Gulf of Patience. 10 km (6 mi) before it enters the sea, the river divides into two arms, which flow into the sea 5 km (3 mi) apart from each other. The two branches create a marshy river island in the middle. The town of Poronaysk is located near the western mouth of the river.
The Poronay is crossed by only two bridges, one rail and one road bridge. Both bridges are next to each other, in the middle of the river between the towns of Pobedino and Pervomaysk. The river valley, especially the area between the downstream Poronay and the Deer River (a small river to the east), has many lakes.
