The floods followed five days of downpours, the Jakarta Globe reported.
"People have fled to safe areas, and in some places, the floodwater has started to recede," Kamarsyah, the South Aceh deputy district head, told Antaranews.com. "We still need tents for the refugees."
No deaths were reported as of Saturday as a direct result of the flooding. A 5-year-old boy was killed in the village of Miten in West Simeulue when a coconut tree fell on his home, and one person was missing after a motorboat operated by the South Aceh Disaster and Mitigation Agency sank.
Aceh on the northern end of the island of Sumatra was close to the epicenter of the 2004 Indian Ocean earthquake and was hit hard by the tsunami that followed.
