Potholes Reservoir

From Wikipedia, the free encyclopedia

Potholes Reservoir
Location Central Washington
Lake type reservoir
Basin countries United States

The Potholes Reservoir is part of the Columbia Basin Irrigation Project. It is formed by the O'Sullivan Dam and located in central Washington, in the United States. The reservoir is fed by water from Moses Lake, part of the Crab Creek basin.

The area features several lakes (typically 30-70 yards wide and 10-30 feet deep). These lakes, known as "potholes" were created through both natural and man made processes. The potholes were initially carved out during the Pleistocene by flood waters originating from Glacial Lake Missoula. [1] Subsequent damming of the area by the Columbia Basin Project raised the water table high enough to allow these topographical depressions to become lakes.

[edit] Recreation

On the shore of the reservoir is Potholes State Park, a 640-acre (2.6 km²) member of the Washington State Park System. It has 6,000 feet (1,800 m) of shoreline on the reservoir.[2]
