A woman who was found dead at a reservoir is yet to be identified, with police appealing for public help to uncover who she is.

The woman was discovered about 1.35pm on Sunday at the Enoggera Reservoir in Brisbane’s outer east.

Detectives believe she was aged in her 30s or 40s.

She was described as having light skin, brown hair and a petite build.

She was wearing black tights, a white‑and‑black striped sports bra, a black singlet, a white long‑sleeve button‑up shirt, black Nike joggers and a gold hair clip.

Police are urging anyone who recognises the description or has information about her identity to come forward.

Enoggera Reservoir, located adjacent to the Gap in Brisbane, was built in 1866 and is the first major dam constructed in Queensland. It is a popular tourist location.

Investigations into the circumstances surrounding her death are continuing.
