Lake Manly was the lake that filled Death Valley during each glacial period from at least 240,000 years ago to as late as 10,500 years ago; the lake typically dried up during each interglacial period, such as the current one. Lake Manly was the last in a chain of lakes that were fed by the Amargosa and Mojave Rivers, and possibly also the Owens River; it was also the lowest point in the Great Basin drainage system. At its height during the Last glacial period some 22,000 years ago, water filled Lake Manly to form a body of water that may have been deep and long. Much smaller lakes filled parts of Death Valley during interglacials; the largest of these was deep and lasted from 5000 to 2000 years ago. Panamint Lake filled Panamint Valley to a maximum depth of ; when it was full, Panamint Lake overflowed into Lake Manly somewhere around the southern end of the Panamint Mountains.
