The Garden Island says the drowning victim is identified as 65-year-old Gayle Kelly.
Kelly died after getting caught in a current while snorkeling with other swimmers off Haena Beach Park April 16.
Responders on rescue boats and a jet ski were unable to resuscitate Kelly.
Authorities say the other snorkelers were able to make it back safely after the current pulled them out to deep water.
The death was Kauai's second drowning this year.
