The Eel River is a 315 km long river in the northwest of the US state California . It drains an area of 9540 km².
Origin of name
The name Eel River means "eel river", but is derived from the similar looking lampreys of the species Entosphenus tridentatus found in the river .
River course
The Eel River rises on the southern slope of the 2052 m high Bald Mountain in Mendocino County . It initially flows to the southeast, but then turns to the west and finally to the northwest. At the headwaters, the river is dammed up from Scott Dam to Lake Pillsbury and from Cape Horn Dam to Lake Van Arsdale . Much of the water from Lake Van Arsdale is diverted south to the Russian River via a tunnel . The Eel River now winds its way north-northwest through the California Coast Mountains . The Eel River flows through the counties of Trinity , Mendocino , Lake and Humboldt . At the lower reaches of the US Highway 101 runs along the river, see Highway 101 along the Eel River . The last bridge over the river is the Fernbridge , over which State Route 211 runs. This is followed by an approximately 10 km long estuary to the confluence with the Pacific Ocean northwest of Ferndale .
Tributaries
Important tributaries of the Eel River are the Middle Fork Eel River , North Fork Eel River , Van Duzen River from the right and South Fork Eel River from the left.
Others
Due to the geologically unstable location in the catchment area, landslides occur again and again. In addition, structural measures along the river bank are increasing soil erosion. This leads to a high sediment load in the Eel River and its tributaries.
On January 19, 1981, a total of 640 km in the river system of the Eel River was designated as a National Wild and Scenic River . The section of the Eel River below Lake Van Arsdale was placed under protection. In the lower reaches of the Eel River coming King Salmon ( Chinook ) and Steelhead trout before.
