Named as 'Sindhu', the lioness died Friday evening, zoo authorities here said.
It had been suffering from health issues for some time, they said adding the health condition of the other lioness, Bindhu, was also not too good.
The only male lion left in the Park, located about kms away from here, had died three years ago.
The picturesque park had over 15 lions.
As their number had exceeded in the later years, the male lions were sterilized by the authorities.
The long-drawn efforts to bring more lions to the park is yet to achieve any desired result.
