The Loobu River (Estonian: Loobu jõgi) is a river in northern Estonia, located entirely within Lääne-Viru County. It is one of several rivers in the region that flow into the Gulf of Finland, an arm of the Baltic Sea.
Geography The Loobu River originates in the northern part of the Ohepalu bog, near the village of Loobu in Kadrina Parish, Lääne-Viru County. Its source lies west of Lake Viitna. From its source, the river flows generally northward through a landscape characterized by forests and some agricultural areas.
The river has a total length of approximately 22.6 kilometers (14.0 miles), and its drainage basin covers an area of about 97.3 square kilometers (37.6 sq mi). The Loobu River's lower course traverses the protected area of Lahemaa National Park before emptying into Eru Bay, which is part of the Gulf of Finland.
Ecology and Conservation The Loobu River is known for its relatively good water quality, which supports a diverse aquatic ecosystem. The river's ecological significance is particularly high within Lahemaa National Park, one of Estonia's oldest and largest national parks. The river provides important spawning and living habitats for various fish species, including brown trout (Salmo trutta) and Atlantic salmon (Salmo salar), especially in its lower reaches. The surrounding riparian zones and adjacent forests contribute to the region's overall biodiversity.
Human Interaction The Loobu River flows primarily through rural areas with limited major settlements directly on its banks. Its course within Lahemaa National Park emphasizes its value for nature conservation and offers opportunities for recreational activities such as hiking and fishing (subject to local regulations). The river and its basin are an integral part of the local natural landscape and support the rural environment.
