The Plaosan Temple which was built during the eighth and tenth century AD is one of four temple complexes in the Prambanan Area, Central Java, Indonesia. On going excavation in the temple complex discloses the occurance of canals along the outer fences. The canals are eight meters wide and four meters deep. This article aims at reconstructing archaic river course and groundwater condition due to the construction of the canals. Aerial photo interpretation, excavation, groundwater level measurement and valley morphology measurement reveals an anomaly of the nearest river in the temple complex. The river had seemingly been bypassed south-eastward to its tributary just before entering Plaosan Temple complex. Groundwater level dropped and its flow direction changed from nearly southward to south-eastward direction. These phenomena indicatse that the canals were groundwater-discharged canals.
