September 20, Colombo (LNW): The Irrigation Department has issued flood warnings for several low-lying areas following significant rainfall in the upper catchment regions of the Kuda Ganga, Maguru Ganga and Mahaweli River.
According to the Department, substantial rainfall had been recorded in the upstream catchment of the Kuda Ganga sub-basin of the Kalu Ganga by 9.30am today (20).
An assessment of rainfall patterns and water levels recorded at hydrological monitoring stations along the Kalu Ganga indicates that minor flooding could occur in low-lying areas surrounding the Kuda Ganga and Maguru Ganga.
The areas considered most vulnerable include sections of the Bulathsinhala, Madurawala and Palindanuwara Divisional Secretariat divisions.
The Department said roads crossing the floodplains of the Kuda Ganga and Maguru Ganga could also be affected if water levels rise, with some routes potentially becoming inundated.
Residents living in vulnerable locations have been urged to remain vigilant and closely monitor developments, while motorists have been advised to exercise particular caution when travelling through areas prone to flooding.
A separate warning has also been issued for communities living near the Mahaweli River.
Heavy rainfall in the river’s upper catchment over the past several hours has increased the possibility of minor flooding in low-lying areas within the Pasbage Korale Divisional Secretariat division.
People living close to the Mahaweli River have been advised to keep a close watch on changing water levels and take precautionary measures to protect themselves and their property.
Motorists using roads in potentially affected areas have likewise been urged to exercise caution, particularly where water begins to accumulate or river levels rise rapidly.
The Irrigation Department has also called on disaster management authorities and other relevant emergency services to remain prepared and take appropriate action should conditions deteriorate.
Authorities have stressed the importance of responding promptly to changes in river levels, particularly in areas where communities, roads and other infrastructure are situated close to riverbanks and floodplains.
