There is a flood,’ like we do when there is fire People pick up their things and leave For two months, we do not sleep, we keep watching twenty four hours wondering when the flooding will start By the time Ratu khola, which flows along the boundary between Dhanusa and Mahottari districts, reaches Sarpallo VDC it splits up into Jungha and Auksi rivers During four months around the monsoon, these streams are responsible for excessive damage A flood that happened two years ago, took the lives of four villagers Because of a community based flood early warning system installed in Ratu khola the residents of Sarpallo village are able to find out about floods as they occur 46 kilometres upstream They now have plenty of time to secure their lives during such occurrences At a total cost of NPR 400,000, the installment of a transmitter for measuring water level along with a receiver has secured the lives of villagers threatened by Ratu khola in 25 VDCs in Mahottari including Sarpallo, Nainahi, Sadha, Ratwada, and Gananpura Interview: Mahendra Bikram Karki, gauge reader, Laalgadh, Dhanusa There is an incoming level-2 flood.
