A five-member expert diving team from Orissa on Thursday conducted a survey in the Mullaperiyar dam to identify areas which needed further studies.
The team which reached the dam area at 10.30 a.m. conducted diving exercises, though it was abandoned by noon due to extreme cold in deep waters.
The visit of a technical team consisting of officials of the Central Soil and Material Research Station, New Delhi, and the Central Water Power Research Station, Pune, entrusted by the high power committee appointed by the Supreme Court for conducting technical study on the condition of the dam left the area by evening.
They collected samples of the materials used for constructing the dam and marked three areas for future analysis.
During its next visit, the team will study the dam's condition in the deepwater areas using modern equipment. The team collected details of the areas where Kerala claimed that excess leakages were noticed, which clearly showed the poor condition of the dam.
The technical team will submit a report to the high power committee to pave way for the final technical analysis of the dam's safety.
Meanwhile, M. Sasidharan, Mullaperiyar special cell member, who accompanied the team, alleged that the expert team conducted the analysis with a partial mind supporting the interests of Tamil Nadu.
He said the report of the team was likely to be in favour of supporting the interests of Tamil Nadu, which claimed that the dam was safe and posed no threat to the people living downstream.
