Lower Klamath Lake

Lower Klamath Lake is a lake in Siskiyou [County, California]. At one time it was connected to Upper [Klamath Lake]. It currently is used to hold overflow water for Klamath Project irrigation uses.
The lake is in Northern California, near the border with Oregon. The Lower Klamath [National Wildlife Refuge], which covers the northern part of the lake, extends from California into Oregon.
The area around the lake was in the homeland of the indigenous Modoc people, prior to mid−19th century Anglo−American immigration.
