West Baray Lake is a baray, or reservoir, at Angkor, Cambodia, oriented east-west and located just west of the walled city Angkor Thom. Rectangular in shape and measuring approximately 7.8 by 2.1 kilometers, the West Baray is the largest baray at Angkor. Its waters are contained by tall earthen dikes. In the center of the baray is the West Mebon, a Hindu temple built on an artificial island.
