1887.
But in recent years this dam
became an issue for interstate dispute.

wanted to raise in height of what level permitted for water level in Dam, but
Kerala opposed. Supreme Court allowed Tamil Nadu to raise water level to 142ft..
Meanwhile Kerala State Government amended Irrigation and Water Conservation Act
but was turn down by Apex Court.
In 2006, Mullaperiyar
Samrakshana Samithi (MSS) was formed my people living in downstream of dam.

districts in Kerala. Their protest continued till 2014 when Supreme Court
declared Mullaperiyar Dam as a safer one.
