The Lake Manly lake system as it might have looked during its last maximum extent 22,000 years ago. (USGS image)

Lake Manly was a large freshwater lake which filled the Death Valley (United States) basin prior to the dry climatic period which has prevailed since the last ice age. Lake Manly receded due to increased evaporation, and to isolation from the Colorado River system, to which it was once connected. At its greatest extent Lake Manly was roughly 80 miles long and 800 feet deep. USGS image from http://www2. ... For the village on the Isle of Wight, see Freshwater, Isle of Wight. ...

As Lake Manly evaporated to the surface of Death Valley, it left a remarkable legacy. Under the surface of Death Valley is one of the world's largest underground reservoirs (aquifers). Being fed by the Amargosa River and Salt Creek, this aquifer is barely visible above ground at Badwater, the lowest point in the valley (282 feet below sea level). An aquifer is an underground layer of water-bearing permeable rock or unconsolidated materials (gravel, sand, silt, or clay) from which groundwater can be usefully extracted using a water well. ...

Shoreline Butte has easy-to-see weak shorelines on it called strandlines that were formed by wave action from Lake Manly. These features were created by different stands of the lake, which would change its depth over time and also cause slight changes in climate. The conditions under which this lake existed are called pluvial by geologists instead of glacial because glaciers did not directly touch Death Valley - but the meltwater from the glaciers and the cooler and wetter temperatures of the time did affect the valley. Approximately 8000 feet (about 2500 m) of gravel, sand, and mud overlay the bedrock of the valley floor. A pluvial lake is a lake which experiences significant increase in depth and extent as a result of increased precipitation and reduced evaporation. ...

In 2005, large amounts of flooding resulted in Lake Manly's reappearing on a large scale. Over a hundred square miles were covered by the lake, allowing some tourists and park rangers to become probably the only humans to canoe across the valley. The lake was about two feet at its deepest point. As a result, it evaporated quickly, leaving behind a mud-salt mixture.

Lake Manly is named in honor of William L. Manly, who was among the original Death Valley party in 1849. Manly and a companion walked out of Death Valley to the Los Angeles area, where he found help and returned to Death Valley to assist the rest of the party out. His autobiography is Death Valley in '49, which he wrote later in life. William Lewis Manly (St. ... 1849 was a common year starting on Monday (see link for calendar). ...
