The '''Poronay''' ({{langx|ru|Поронай}}, {{langx|ja|幌内川}}) is the longest river on the [island](/source/island) of [Sakhalin](/source/Sakhalin) in [Russia](/source/Russia). It flows in a southerly direction through [Tym](/source/Tymovsky_District), [Smirnykhovsky](/source/Smirnykhovsky_District) and [Poronaysky](/source/Poronaysky_District) Districts.
==Geography==
The river begins on Mt. Nevel in the East Sakhalin Mountains, flows south through the swampy [wetlands](/source/wetlands) of the [Tym](/source/Tym_(Sakhalin))-Poronay Valley, and enters the [Sea of Okhotsk](/source/Sea_of_Okhotsk) in the [Gulf of Patience](/source/Gulf_of_Patience). {{convert|10|km|mi|abbr=on|0}} before it enters the sea, the river divides into two [arms](/source/Distributary), which flow into the sea {{convert|5|km|mi|abbr=on|0}} apart from each other. The two branches create a marshy [river island](/source/river_island) in the middle. The town of [Poronaysk](/source/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](/source/Valley), especially the area between the downstream Poronay and the Deer River (a small river to the east), has many lakes. The Poronay river system is a rich breeding ground for [salmon](/source/salmon)[[http://slovari.yandex.ru/%D0%9F%D0%BE%D1%80%D0%BE%D0%BD%D0%B0%D0%B9/%D0%91%D0%A1%D0%AD/%D0%9F%D0%BE%D1%80%D0%BE%D0%BD%D0%B0%D0%B9/ Poronay] {{Webarchive|url=https://web.archive.org/web/20130922172444/http://slovari.yandex.ru/%D0%9F%D0%BE%D1%80%D0%BE%D0%BD%D0%B0%D0%B9/%D0%91%D0%A1%D0%AD/%D0%9F%D0%BE%D1%80%D0%BE%D0%BD%D0%B0%D0%B9/ |date=2013-09-22 }} - an article in the [Great Soviet Encyclopedia](/source/Great_Soviet_Encyclopedia).

===Hydrology===
The river is fed by both [snowmelt](/source/snowmelt) and [rain](/source/rain). Average [water flow](/source/River_flow) is 120 m³/s. The highest level of flow has been observed in early May, and the lowest in the second half of September. The river usually freezes in the second half of November, while the ice thaws in late April.
