Lake Isabella is at the confluence of the North and South Forks of the Kern River. These rivers are 'wild', in that they are not controlled by any dam upstream. Upstream on the North Fork white water enthusiasts play in the spring and early summer. The famous Golden Trout originate in these rivers in the high country to the north.
The area was inhabited for millennia by the indigenous Tübatulabal and Owens Valley Paiute.
