Local authorities 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 has inundated houses and some 5,000 rai (800 hectares) of farmland in some areas since Friday evening. The local officials said the water further rose late at night to affect houses in other areas.

Altogether the flooding affected over 600 houses.

A 500-metre section of a local road was also flooded, according to Prasit Poonpraser, chief disaster prevention and mitigation officer of the district.
