The upstream portion is near Tecopa and passes through the Amargosa Canyon. The lower portion is northwest of Saratoga Springs, just at the head (southern inlet) of Death Valley, where the Amargosa River turns north to enter the valley.[2] These dimunitive fish subsist on cyanobacteria and algae. They have a life history adapted to the vagaries of the intermittent nature of their environment. They have a very short generation time (<1 year and usually just a few months), which allows for rapid exploitation of flooded portions of the streambed in years of high flow.
