Idukki district authorities are keeping a close watch on the rising waters in the Idukki dam, where an "orange alert" has been issued as the water level touched 2,395m.

A red alert would be sounded if the waters reach 2,399 metres, paving the way for opening the floodgates of the dam, which have not been opened since 1992.

Even though the catchment areas of the dam have been receiving rains, the intensity is just one-third of what it was earlier. The authorities, however, are confident that there is nothing to worry about.
