One (Thorthormi-Lake) of four potential dangerous lakes in the head waters of Phochu under the Punatsangchu is partially bridged 20th June night.The stability of the moraine walls surrounding the main lake is uncertain.The chief of hydrology and water resources division, Sangay Tenzin said this is because of the two subsidiary lakes that breached on the evening of June 20. There is erosion and an outflow from the subsidiary II lake, which could destablise the moraine dams of the main Thorthomi lake.
