The Takase River (高瀬川, Takasegawa) is a Class A river system that flows through Aomori Prefecture, Japan. It flows from Mt. Yahata, through Lake Ogawara into the Pacific Ocean.[1][2]
The river is very important to the economy of the region.[1] Approximately 80,000 people live in the river's catchment area.[1]
Every July, the annual Lake Festival (湖水まつり, Kosui-matsuri) is held along the banks of the Takase River.[3] The Takase River Office uses the opportunity to exhibit the "creatures that live in Lake Ogawara", which is popular with families.[3] They also raise awareness about flood control, and water quality improvement of the lake.
The river has a length of 64 kilometres (40 mi) and a catchment area of 867 square kilometres (335 sq mi).[1][4][5] The basin area contains 2 cities, 4 towns, and 1 village.[5]
Upstream from Lake Ogawara, the slope of the river ranges between 1:50 and 1:2000.[5] Between the river and the Pacific Ocean, the slope is 1:30000 (almost horizontal).[5] The water flows backwards from the sea into Lake Ogawara, causing it to be slightly brackish.[5]
