Local officials said rains unleashed by the tropical storm Talas caused the water level in Pakchan and Lam Khanchu canals to rise. The irrigation dyke downstream from the canals overflowed from their combined water. The water started inundating houses and some 5,000 rai (800 hectares) of farmland in tambon Koh Manao, and tambon Ban Chuan since Friday evening. The officials said the water further rose late at night to affect houses in tambon Khok Phet as well. All in all, the floods hit over 600 houses in the three tambons.
